Under
the Great Lake Water Quality Agreement, Lakewide Management
Plans (LaMPs) have been charged with evaluating impairments
of beneficial uses of various natural resources caused
by priority pollutants. This report assessed deformities
and reproductive impairments in wildlife species of Lake
Erie. ... The use of TFM, which
is intended to control larval lamprey, is likely to kill
amphibians wherever it is used in Lake Erie tributaries.
Deformity rates in mudpuppies at Long Point and
in the Detroit River are elevated well above the background
rates reported for inland areas of the Great Lakes and
St. Lawrence River basin. A risk assessment using species-specific
biomagnification factors was conducted to compare ambient
water concentrations of PCBs to concentrations that have
been shown to have no effect in laboratory and (or) field
studies. For all species assessed (Bald Eagles, Herring
Gulls, Double-crested Cormorants, Caspian Terns and mink),
PCB concentrations in Lake Erie water were nine to 1,550
fold higher than no effect concentrations. |

The
lampricide 3-trifluoromethyl-4-nitrophenol (TFM) is used
to selectively kill sea lampreys (Petromyzon marinus) in
the tributaries of the Great Lakes. Over the years, TFM
was tested most often on nontarget fishes and only occasionally
on invertebrates, including freshwater mussels. The authors
exposed pink heelsplitters (Potamilus alatus) to TFM concentrations
and exposure times similar to those in lampricide treatments.
Tests were conducted in water similar in quality to the
Poultney River, New York, a stream that contains pink heelsplitters
and is scheduled for lampricide treatment in 1991. Mussels
were exposed to TFM for either 12 or 24 h and observed daily
in well water for 14 days. Ninety percent of the mussels
exposed to 3.5 mg of TFM for 12 h survived, however, only
50% of the mussels exposed to that concentration for 24
h survived. TFM seems to narcotize or anesthetize mussels.
Mortality of mussels exposed to 3.5 mg/L TFM for 12 h seemed
to be 60% immediately after treatment but the a [asbstract

Abstract—The
contamination of field formulations of the lampricide
3-trifluoromethyl-4-nitrophenol (TFM) by a dibenzo-p-dioxin
containing -chloro, -nitro, and -trifluoromethyl substituents
was suspected from chemical fractionations of a TFM
formulation that were directed by mixed function oxidase
(MFO) induction in rainbow trout. Three dioxin isomers
containing these substituents in field formulations
were identified by gas chromatography–mass spectrometry
(GC-MS). Short-term waterborne exposures to a mixture
of two isomers, 2-trifluoromethyl-3-nitro-7- (and 8)-chloro-dibenzo-p-dioxin,
elevated MFO activity in trout, with a threshold between
0.148 and 0.745 nM (4.1–20.5 ng/L). Synthetic
preparations of other dioxins related to formulation
impurities enabled characterizations of this previously
unknown family of dioxin congeners by GC-MS. The elution
order of the isomers followed those established for
halogenated dioxins except where there was a lone -nitro
substitution on one ring. The average concentration
of these compounds in TFM formulations spanning more
than a decade was 288 6 47 mg/L, which translates into
an annual loading of approximately 40 g to the Great
Lakes Basin. Using mammalian (H4IIE) and fish (PLHC-1)
in vitro assays, a 2,3,7-substituted chloro-nitro-trifluoromethyl
isomer was a four to five times more potent inducer
of MFO activity than 2,3,7-trichlorodibenzo-p-dioxin.
Characterizations of the synthetic isomers indicate
that the isomers present in the formulation are not
substituted in the 2,3,7- positions and are relatively
weak inducers of MFO activity.

Abstract—Recently,
a field formulation of the lampricide containing 3-trifluoromethyl-4-nitrophenol
(TFM) was identified as a potent inducer of mixed-function
oxygenase (MFO) detoxification enzymes in fish. It was
further shown that induction was not associated with
primary formulation ingredients. Using a toxicity identification
evaluation (TIE) approach based on rainbow trout hepatic
MFO activity, the TFM field formulation was investigated
to isolate the compound(s) responsible for induction.
Solid phase extraction and reverse-phase high-pressure
liquid chromatography (HPLC) isolated activity in two
distinct fractions, which were profiled by gas chromatography–high-resolution
mass spectrometry. The major constituents in both fractions
were confirmed by synthesis as nitro-, trifluoromethyl-,
and/or chloro-substituted diphenyl ethers. However,
fish exposures to the pure compounds failed to cause
MFO induction. After further fractionations by HPLC,
induction was determined in three new subfractions.
Confident identification of a chloro-nitro-trifluoromethyl-substituted
dibenzo-p-dioxin has been made in two of these fractions.
Although the specific chemicals responsible for induction
have not been confirmed, a suite of impurities including
chloro-, and/or nitro-, and/or trifluoromethyl-substituted
phenols, diphenyl ethers, and dibenzo-p-dioxins have
been identified in the formulation. It is likely that
these materials originate during industrial synthesis
of TFM. These findings suggest that additional structurally
related impurities are also present in this formulation.

Abstract—Lampricide formulations containing 3-trifluoromethyl-4-nitrophenol
(TFM) have been associated with induction of hepatic
mixed function oxygenase (MFO) activity and altered
levels of circulating steroids in fish. Bioassay-directed
chemical fractionations have shown MFO induction to
be associated with impurities in TFM field formulations.
Asimilar toxicity identification/ evaluation approach
coupled to competitive binding to rainbow trout estrogen
receptors (ER) was used to identify compounds associated
with estrogenic responses in fish. In contrast to MFO
induction, nearly all binding to the ER was associated
with fractions containing TFM, TFM isomers, and p-chlorophenol.
p-Chlorophenol did not show any affinity for the receptor
when tested separately. Diphenyl ether impurities identified
in the fractions causing MFO induction as well as analogues
to dibenzo-p-dioxins suspected in these fractions also
showed no affinity for the receptor when tested individually.
Relative to estradiol, TFM demonstrated
an affinity of 5.03 3 10 25 , compared to 2.47 3 10
24 for p-nonylphenol, a reported estradiol agonist.
Vitellogenin induction in primary cultures of rainbow
trout hepatocytes indicated that TFM acts as an estradiol
agonist.

Abstract:
Recent laboratory studies with nontarget fish species
have shown that the lampricide 3-trifluoromethyl-4-
nitrophenol (TFM) exhibits estrogenic activity through
binding to rainbow trout (Oncorhynchus mykiss) hepatic
estrogen receptors and induction of vitellogenin in
hepatocyte cultures. In addition, mixed function oxygenase
(MFO) activity associated with exposure to field formulations
has been attributed in part to the presence of chloro-nitro-trifluoromethyl-
dibenzo-p-dioxin impurities. To investigate the environmental
effects associated with these findings, the temporal
and spatial patterns of MFO activity and vitellogenin
induction were monitored in three nontarget fish species
following a TFM field treatment. Elevated MFO activity
was detected as early as 1 day in caged rainbow trout
and activity in trout, wild white sucker (Catostomus
commersoni), and longnose dace (Rhinichthys cataractae)
peaked 2 or 3 days after treatment. Highest activities
were observed in fish exposed closest to lampricide
application points and declined with increasing distance
downstream. After 18 days, MFO activity was reduced
but remained almost sevenfold reference values at several
sites. Plasma vitellogenin was not detected in caged
trout sampled 6 and 18 days post-treatment, and dioxin
impurities were not detected in sediments after treatment.
It was concluded that laboratory testing underestimated
the duration of MFO activity under field conditions
and that an assessment of formulation exposure during
sensitive life stages represents an area for further
study.

(page
13):
The sensitivity of mudpuppies, frog tadpoles and adult
frogs to TFM use in the Great Lakes has been noted (Gilderhus
and Johnson, 1980). TFM is intended to control larval
sea lamprey and has been used historically in 19 (8
in U.S./11 in Canada) of the 842 tributaries to Lake
Erie for sea lamprey (Petromyzon marinus) control. Since
1995, TFM has been applied in Conneaut Creek and the
Grand River in Ohio and Big Creek and Big Otter Creek
in Ontario. Only four Lake Erie tributaries (Big Creek
Ontario, and 3 U.S. tributaries) are currently scheduled
for future regular treatments every 4 to 6 years.
When
TFM is used, amphibians have regularly been found dead
in creeks immediately after treatment in Lake Erie watersheds
and elsewhere in the Great Lakes
(Gilderhus and Johnson, 1980; Matson, 1990).
Laboratory tests have confirmed that species native
to the Great Lakes basin such as gray tree frog, leopard
frog, and bullfrog are sensitive to field applied rates
of TFM (Chandler and Marking, 1975). In the Grand
River, Ohio, Matson (1990) found that in the year following
TFM application (1997), mudpuppy
population size decreased by a minimum of 29% in the
segment treated. In 1999,
the Grand River was treated with TFM and dead mudpuppies
were found downstream of the application zone within
twenty-fours hours.
Because
TFM is not bioaccumulative and is only applied periodically
in closely controlled and monitored conditions, the
associated mudpuppy mortality is often perceived to
be insignificant. However, mudpuppies
do not become sexually mature until 4 to 6 years of
age. Given the past and projected future schedule
for TFM applications, there is the potential for the
TFM applications to match periods when large numbers
of mudpuppy are reaching an age when they can reproduce.
In addition, TFM is generally applied in the spring
when stream flows are higher. Therefore, TFM
has the potential to kill a portion of the existing
females before they lay their eggs in May and June.
For these reasons, future study is needed to determine
the significance of the mortality and the life stages
most affected (see section 7.5).
(page
16)
• There are conflicting opinions about the significance
of non-target species sensitivity, particularly mudpuppy,
to TFM (when used for sea lamprey eradication), and
its implications for potential impairment. Therefore,
the impact of TFM on amphibian populations needs to
be assessed by monitoring populations of mudpuppies
and other amphibians pre- and postapplication.
From a reproductive standpoint, it is particularly important
to determine if TFM has greater impacts on certain age
classes and/or egg-bearing females.

The selective sea lamprey (Petromyzon marinus) larvicide 3-trifluoromethyl-4-nitrophenol
(TFM) is currently used to control parasitic sea lampreys in
tributaries to the Great Lakes basin. The concentration and
persistence of TFM and its major metabolite, TFM glucuronide
(TFM-glu), was determined in fillet tissue of fish after a typical
stream application. Rainbow trout (Oncorhynchus mykiss) and
channel catfish (Ictalurus punctatus) were exposed to a nominal
concentration of 12.6 nmol/mL TFM for about 12 h during a sea
lamprey control treatment of the Ford River in Michigan. Concentrations
of TFM and TFM-glu were greatest in the fillet tissues during
the exposure period, with greater residues in channel catfish
(wet wt; mean, 6.95 nmol/g TFM; mean, 2.40 nmol/g TFM-glu) than
in rainbow trout (wet wt; mean, 1.45 nmol/g TFM; mean, 0.93
nmol/g TFM-glu). After the exposure period, residues in both
species decreased by 90-99% within 6-12 h and were less than
the quantitation limit (<0.03 nmol/g) within 36 h.

Rainbow trout (Oncorhynchus mykiss) and channel
catfish (Ictalurus punctatus) were exposed to 3-trifluoromethyl-4-nitrophenol
(TFM) and Bayluscide (niclosamide) during a sea lamprey control
treatment of the Ford River, located in the upper peninsula
of Michigan. Caged fish were exposed to a nominal concentration
of 0.02 mg/L of niclosamide for a period of approximately 12
h. Samples of fillet tissue were collected from each fish species
before treatment and at 6, 12, 18, 24, 48, 96, and 192 h following
the arrival of the block of chemical at the exposure site. The
fish were dissected, homogenized, extracted, and analyzed by
high-performance liquid chromatography. The major residues found
in the fillet tissues were TFM and niclosamide. Niclosamide
concentrations were highest 12 h after arrival of the chemical
block for rainbow trout (0.0395 +/- 0.0251 microg/g) and 18
h after arrival of the chemical block for channel catfish (0.0465
+/- 0.0212 microg/g). Residues decreased rapidly after the block
of lampricide had passed and were below the detection limits
in fillets of rainbow trout within 24 h and channel catfish
within 96 h after the arrival of the lampricide.

3-Trifluoromethyl-4-nitrophenol (TFM) is a pesticide
used for the selective control of sea lampreys (Petromyzon marinus)
in stream and river tributaries of the Great Lakes. To determine
concentrations of TFM and TFM glucuronide in the edible fillet
tissue of fish during sea lamprey control treatments, an analytical
method was developed to determine the concentrations of these
residues in rainbow trout (Oncorhynchus mykiss; RBT) and channel
catfish (Ictalurus punctatis; CCF). Homogenized fillets were
extracted with methanol-water (80 + 20). TFM and TFM glucuronide
were isolated from coextractives by C18 solid-phase extraction.
TFM glucuronide was hydrolyzed to TFM by the addition of beta-glucuronidase
to the TFM glucuronide extract. The extracts were analyzed separately
by liquid chromatography with UV-visible detection. Recoveries
from TFM-fortified CCF and RBT tissues were 84.1 and 96.1%,
respectively. The method detection limits (MDLs) are 2.4 ng/g
for TFM-fortified tissues of CCF and 3 ng/g for those of RBT.
Recoveries were 78.8 and 77% from TFM glucuronide-fortified
CCF and RBT tissues, respectively. The MDLs for TFM glucuronide-fortified
tissues are 3.5 and 6.9 ng/g for CCF and RBT, respectively.

Bayluscide [the ethanolamine salt of niclosamide
(NIC)] is a registered piscicide used in combination with 3-(trifluoromethyl)-4-nitrophenol
(TFM) to control sea lamprey populations in streams tributary
to the Great Lakes. A high-performance liquid chromatography
(HPLC) method was developed for the determination of NIC residues
in muscle fillet tissues of fish exposed to NIC and TFM during
sea lamprey control treatments. NIC was extracted from fortified
channel catfish and rainbow trout fillet tissue with a series
of acetone extractions and cleaned up on C(18) solid-phase extraction
cartridges. NIC concentrations were determined by HPLC with
detection at 360 and 335 nm for rainbow trout and catfish, respectively.
Recovery of NIC from rainbow trout (n = 7) fortified at 0.04
microg/g was 77 +/- 6.5% and from channel catfish (n = 7) fortified
at 0.02 microg/g was 113 +/- 11%. NIC detection limit was 0.0107
microg/g for rainbow trout and 0.0063 microg/g for catfish.
Percent recovery of incurred radioactive residues by this method
from catfish exposed to [(14)C]NIC was 89.3 +/- 4.1%. Percent
recoveries of NIC from fortified storage stability tissue samples
for rainbow trout (n = 3) analyzed at 5 and 7.5 month periods
were 78 +/- 5.1 and 68 +/- 2.4%, respectively. Percent recoveries
of NIC from fortified storage stability tissue samples for channel
catfish (n = 3) analyzed at 5 and 7.5 month periods were 88
+/- 13 and 76 +/- 21%, respectively.

BIOSIS COPYRIGHT: BIOL ABS. Laboratory-based static acute toxicity
tests were performed to determine the relative toxicity of TFM
to selected species of tadpoles and ornamental fish in soft
(mean, 45 mg as CaCO3) and hard (mean, 177 mg/L) freshwater.
Sensitivity was measured as the 96-h LC50, the concentration
lethal to half the test animals in 96 h. The sensitivity of
larval bullfrogs Rana catesbeiana to TFM was 1.50 mg/L in soft
water and 4.20 mg/L in hard water. The 96-h LC50 of TFM for
larval southern toads Bufo terrestris was 0.51 mg/L in soft
water and 0.70 mg/L in hard water. Toxicity of TFM (96-h LC50)
to the fish tested ranged from 1.02 to 7.73 mg/L in soft water

was associated with the 3-trifluoromethyl-4-nitrophenol (TFM)
formulation, and not the 2',5-dichloro-4'-nitrosalicylanilide

that reverse phase HPLC successfully separated the inducing

kills of some species of aquatic insects have accompanied periodic
lampricide treatments (3-trifluoromethyl-4-nitrophenol; TFM)

These kills prompted concern among trout anglers and Department

was heightened during the early 1980s by declines in several
of the river's trout populations that use aquatic insects as
a food resource. Hence, benthos collections throughout the drainage
basin, and drift-net samples from 3 tributaries, were made between
November 1983 and July 1988 to document and assess the status

TD3: The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) is
used to selectively kill sea lampreys (Petromyzon marinus) in
the tributaries of the Great Lakes. Over the years, TFM was
tested most often on nontarget fishes and only occasionally
on invertebrates, including freshwater mussels. The authors
exposed pink heelsplitters (Potamilus alatus) to TFM concentrations
and exposure times similar to those in lampricide treatments.
Tests were conducted in water similar in quality to the Poultney

and is scheduled for lampricide treatment in 1991. Mussels were
exposed to TFM for either 12 or 24 h and observed daily in well

mussels exposed to 3.5 mg of TFM for 12 h survived, however,
only 50% of the mussels exposed to that concentration for 24

ambient stream pH and at an increased pH (raised approximately
1 unit by the addition of sodium hydroxide). At all but one
concentration, TFM killed all sea lampreys and none of the target
fish. Selectivity decreased when the pH was lowered by approximately

for larval lamprey from 1963 to 1987 indicated that sea lamprey
have not developed increased resistance to TFM. Maintenance
of current control practices are unlikely to cause the development
of TFM-resistant sea lamprey strains in the foreseeable future.

Procedures
for use of freshwater fishes in the development of reproducible
toxicological information.
Marking LL.
Toxicity testing with fish began early in this century, but
standardized methods have been developed only within the last
three decades. Standardized test procedures promote reproducibility
of results; healthy fish properly handled and acclimated to
test conditions are a given prerequisite. The principles of
acute toxicity testing are important in the design of chronic
tests for suspected carcinogens because certain factors influence
the activity of chemicals or contaminants. The pH of test water
is a critical factor in governing the uptake of chemicals by
fish. Buffering is required so that uniform pH in waters of
different hardnesses and different pHs in water of a given hardness
are maintained. The importance of water quality control is graphically
demonstrated by the lampricide 3-trifluoromethyl-4-nitrophenol;
the toxicant is over 50 times more toxic
in water at pH 6.5 than at pH 9.5. Results of laboratory
tests on toxicity or carcinogenicity of single compounds in
a clean environment represent an oversimplification of the real
world because organisms are actually exposed to multiple chemicals
or stresses. Because the environment is a complex interaction
of physical, chemical, and biological factors that are extremely
variable and dynamic, simulation of these systems in the laboratory
is, at best, artificial; therefore, results developed must be
considered to be predictive.

TFM in Lake Superior water could approach, if TFM were a completely
conservative chemical, 0.015 mug/l. This concentration was considerably
less than the concentrations found to be acutely and chronically
toxic to aquatic life. The use of TFM as a sea lamprey larvicide
did not represent a hazard to fish and other nontarget aquatic
life in the Great Lakes.

PESTAB. The chemicals 3-trifluoromethyl-4-nitrophenol (TFM)
or a combination of TFM and 2',5-dichloro-4'-nitrosalicylanilide
(Bayer 73, clonitralide) have been used to control the sea lamprey
(Petromyzon marinus) in the Great Lakes for about 20 yr. These
chemicals cause some mortalities of Oligochaeta and Hirudinea,
immature forms of Ephemeroptera (Hexagenia sp.), and certain
Trichoptera, Simuliidae, and Amphibia (Necturus sp.). The combination
of TFM and Bayer 73 may affect some Pelecypoda and Gastropoda,
but its overall effects on invertebrates are probably less than
those of TFM alone. Granular Bayer 73 is likely to induce mortalities
among oligochaetes, microcrustaceans, chironomids, and pelecypods.
No evidence exists that the lampricides have caused the catastrophic
decline or disappearance of any species. The overall impact
of chemical control of sea lampreys on aquatic communities has
been minor compared with the benefits derived. (Author abstract

1. Residues of the lampricides 14C-Bayer 73 (2',5-dichloro-4'-nitrosalicylanilide)
and 14C-TFM (3-trifluoromethyl-4-nitrophenol) were absorbed
from aqueous sublethal concn. by aquatic larvae of the midge
Chironomus tentans.
2. Toxicant residues were widely distributed during early hours
of exposure, but later and during a 24-h post-exposure period,
they became concentrated in the trunk and intestinal tract;
the posterior movement of Bayer 73 was more rapid than that
of TFM.
3. During 4-h tests, Malpighian tubules of the chironomid actively
transported Bayer 73 and TFM in vitro, and on a per tubule basis,
more TFM was transported than Bayer 73.
4. Potassium cyanide inhibited tubule transport; serotonin had
no effect.

HEEP COPYRIGHT: BIOL ABS. Growth and age at metamorphosis were
determined for populations of larval sea lampreys that became
reestablished after chemical treatments of tributaries of Lakes
Superior and Michigan (USA) with the selected lampricide, 3-trifluoromethyl-4-nitrophenol.
Age at metamorphosis varied from 3-7 yr. Growth of ammocetes
varied considerably from stream to stream and within streams.
Mean lengths of ammocetes of age group III in late summer or
early fall in different streams ranged from 65-144 mm. Ammocetes
of the 1st yr class established after a chemical treatment grew
faster than those of succeeding year classes. Transformation
at an early age usually occurred only among fast-growing larvae
in large streams. A reversal of the sex
ratio, from predominately male to predominately female, followed
the reduction of the adult sea lamprey population. Sex ratios
of larval and recently metamorphosed sea lampreys reestablished
after chemical treatments rapidly shifted from an excess of
males to an excess of females. The shift in sex ratio
was related to decreased densities of sea lampreys resulting
from treatments.

PESTAB. The toxicity of the larval lampricide TFM (3-trifluoromethyl
-4- nitrophenol) for two vascular hydrophytes, Elodea canadensis
and Myriophyllus spicatum, was studied. The plants were obtained
from naturally occurring stocks, and exposure to the toxicant
was conducted in totally recirculating model streams. After
a growth period of up to 2 wk, during which the plants were
exposed to 5.0-35.0 mg/l TFM, the individual shoots were ashed
and the dry weights and ash-free dry weights determined. Analytical
grade TFM inhibited the growth and production of vegetative
shoots of Elodea canadensis at all concentrations greater than
5.0 mg/l. A net loss in biomass occurred following exposure
to 10.0-35.0 mg/l for over 24 hr or to 20.0-35.0 mg/l for over
3 hr. Primary production was also progressively inhibited as
a function of exposure time. Myriophyllum spicatum was more
susceptible to the toxicant. The greatest percentage reduction
in biomass occurred after 1 and 4 hr of exposure to all concentrations
greater than 5.0 mg/l. The toxicant appeared to affect both
species of plants similarly.

Evaluation
of a toxicant on the metabolism on model stream communities.
Maki AW, Johnson HE
PESTAB. The effects of a toxicant, the lampricide TFM (3-trifluoromethyl-
4-nitrophenol), on the metabolism of benthic communities were
studied in a series of six indoor model streams resembling typical
woodland streams. Each artificially illuminated stream consisted
of a 4-m pool section and a 4-m riffle section. A specially
developed in situ stream respirometer was used for measurements
of net primary production and community respiration in pool
and riffle communities. Pretreatment levels of gross primary
production ranged during summer, fall, and early winter from
10.7 to 79.0 mg O2.m-2.h-1 and were suppressed by 25-50% during
exposure to 9.0 mg/liter TFM. Community respiration ranged from
10.5 to 36.2 mg O2.m-2.h-1 during the same time period and was
increased 3-50% by the 9.0 mg/liter lampricide treatment. Calculated
photosynthesis to respiration (P:R) ratios proved to be sensitive
indicators of the influence of the toxicant. The stream communities
demonstrated a capacity to adjust to the toxicant influence
as evidenced by the rapid return of metabolic rates to pretreatment
levels following the exposure period. (Author abstract by permission)

Chemical
control of the sea lamprey: the addition of a chemical to the
environment.
Menzie CM, Hunn JB.
Construction of the Welland Canal enabled shipping to by-pass
Niagara Falls and enter the upper Great Lakes and also eliminated
the barrier to the entry to the lakes by the sea lamprey (Petromyzon
marinus Linnaeus). Within forty years the commercial fisheries
of the Great Lakes was almost eliminated by this parasitic cyclostome.
A search for selective chemical control of the sea lamprey was
undertaken in the 1950's and culminated with the discovery of
TFM (3-Trifluoromethyl-4-nitrophenol). At the request of the
International Great Lakes Fishery Commission, the Bureau of
Sport Fisheries and Wildlife undertook to assess the hazard
of TFM to the aquatic ecosystem, to humans as well as to fish
and wildlife. Studies were undertaken in Bureau laboratories
as well as by contracts with university and private laboratories.
Results of these studies to-date indicate that this material
is not subject to biomagnification and does not pose a hazard
to man or the the environment.

A procedure for the analysis of 3-trifluoromethyl-4-nitrophenol
(TFM) in natural waters is described. The lampricide is extracted
from acidified water samples on the macroreticular resin XAD-7
and eluted from the column with ethyl ether. The ether extract
is dried, concentrated, and partitioned with potassium carbonate.
TFM is acetylated in the aqueous alkaline solution and the acetate
derivative is extracted into benzene for analysis by electron
capture gas-liquid chromatography. Recoveries of TFM from natural
waters exceeded 90% and as little as 0.01 mug TFM can be quantitated

mixture containing 98% 3-trifluoromethyl-4-nitrophenol (TFM)
and 2% Bayer 73 (TFM-2B) to 21 freshwater invertebrates. LC50
values were determined for 24 h exposure periods at 12.8ê
C. Organisms relatively sensitive to Bayer 73 were a turbellarian
(Dugesia tigrina), aquatic earthworms (Tubifex tubifex and Lumbriculus
inconstans), snails (Physa sp.) and (Pleurocera sp.), a clam
(Eliptio dilatatus), blackflies (Simulium sp.), leeches (Erpobdellidae)
and a daphnid (Daphnia pulex). The invertebrates most sensitive
to TFM-2B were turbellarians, aquatic earthworms (Tubifex),
snails (Physa), blackflies, leeches and burrowing mayflies (Hexagenia
sp.). Bayer 73 was generally much more toxic to the test organisms
than TFM-2B. At lampricidal concentrations, TFM-2B was more
highly selective than Bayer 73 against larval sea lampreys (Petromyzon
marinus). (Other invertebrates studied were an isopod (Asellus

Role

(TFM) for the sea lamprey: Comparative aspects of TFM uptake

LECH JJ, STATHAM CN
HEEP COPYRIGHT: BIOL ABS. The comparative aspects of disposition
and conjugation of 3-trifluoromethyl-4-nitrophenol (TFM), a
selective sea lamprey larvicide in sea lamprey (Petromyzom marinus)
and rainbow trout (Salmo gairdneri) were studied. When exposed
to identical water concentrations of TFM, sea lamprey ammocoetes
exhibited a higher rate of accumulation and an increased steady-state
level of TFM compared to trout. Regardless of the life stage
of sea lamprey or size of trout studies, sea lamprey revealed
a higher concentration of free TFM in blood and tissues. The
higher concentration of free TFM in lamprey blood was demonstrated
at a variety of water concentrations of TFM. In vitro glucuronyl
transferase assays demonstrated that the sea lamprey had a lower
rate of formation of TFM glucuronide when compared to trout.
In vivo, sea lamprey exhibited a much higher ratio of free to
conjugated TFM than trout. Pretreatment of sea lamprey and trout
with salicylamide, an inhibitor of glucuronyl transferase, shifted
the LC50 for trout from 9.7 mg/l to 3.6 mg/l and did not alter
the LC50 for sea lamprey.

PESTAB. Mature scud, daphnids, 14-day-old crayfish, mature aquatic
sowbugs, damselfly nymphs, and mayfly nymphs were exposed to
varying concentrations of the lampricide TFM in water. After
a plateau concentration was reached, scud were transferred to
flowing water containing no TFM, and the decline in residues
was measured. Static 96 hr toxicity tests indicated an LC50
of 57 mg/l for scud and 110 mg/l for crayfish for field grade
TFM (35.7% active ingredient). LC50 values from flow-through
chronic toxicity tests of field grade TFM ranged from over 100
for scud and crayfish at 1 day to 14 for scud at 20 and 30 days.
Ratios of TFM concentration in the organism to TFM concentration
in the water ranged from practically 0 after 1 day in damselfly
to 89 after 14 days in scud exposed to 0.510 mg/l TFM. TFM concentration
reached a plateau after 7 days in most organisms. Scud transferred
to TFM-free water after having reached a plateau concentration
eliminated 50% of the TFM in 3.5 days and 98% of the TFM in
14 days. Reproduction was not affected when three generations
of daphnids were exposed to 2.4, 4.9, and 10 mg/l of field grade
TFM. When daphnids were exposed to 18
mg/l field grade TFM, reproduction stopped within the first
generation.

Accumulation of [14C]3-trifluoromethyl-4-nitrophenol ([14C]TFM)

biotransformed to at least two more polar derivatives, including

is also reduced to the phenol amine. Chironomids can quickly
eliminate all TFM derivatives as well as the parent [14C]TFM.

The
effects and fate of lampricide (TFM: 3-trifluoromethyl-4-nitrophenol)
in model stream communities.
Maki AW
PESTAB. The effects of TFM lampricide on the structure and function
of benthic communities were studied in a series of six replicated
indoor model streams. A specially developed stream respirometry
system was used for measurements of net primary production and
community respiration in pool and riffle communities. Pretreatment
levels of gross primary production were suppressed by 25-50%
during exposure to 9. 0 mg/l TFM. Community respiration was
increased 3-50% by TFM treatment. No effects of lampricide could
be demonstrated on periphyton community structure.
A statistically significant decrease in the total number of
macroinvertebrates per unit area was demonstrated following
treatment. Complete recovery to pretreatment densities
was seen in 2-3 months, primarily through drift input. No significant
difference in mean growth rates of treated and control brown
trout was seen. The uptake of TFM residues was demonstrated,
using (SUP)14C-TFM, to be basically an adsorption process. Uptake
was rapid during the first 2 hr of the exposure. Macroinvertebrate
species with soft integument accumulated significantly higher
residue concentrations than species with hard chitinous or calcareous
exoskeletons. TFM declines were correlated with water
current and substrate associations. The mean half-life for riffle
species was 17. 8 hr and for pool-dwelling species was 140 hr.

Microbial degradation of the lamprey
larvicide 3-trifluoromethyl-4-nitrophenol in sediment-water
systems.
KEMPE LL
HEEP COPYRIGHT: BIOL ABS. The selective lampricide 3-trifluoromethyl-4-nitrophenol
(TFM), maintained in the water at concentrations of 1-6 mug/ml
for several hours, kills larval sea lampreys (Petromyzon marinus)
in tributaries of the Great Lakes (Canada, USA). Becuase the
fate of TFM in the environment is a matter of concern, the interactions
of this chemical with river and lake sediments were studied
in laboratory experiments. In mixtures of TFM, water, and sediment
held in aquarium, the TFM decreased progressively and nearly
or completely disappeared in 1-4 wk; concentrations
of the fluoride ion increased; and the systems became
nontoxic for sea lamprey larvae and goldfish (Carassius auratus).
If the reduction in TFM ceased before all of the chemical had
disappeared, the process resumed when nutrient broth was added.
Loss of TFM from the systems was prevented by the addition of
an antiseptic (phenol) and by heat sterilization. Enrichment
cultures of microorganisms isolated from stream and lake sediments
degraded TFM in nutrient broths. TFM was degraded by microorganisms
that live in sediment-water systems.

characteristic yellow color of TFM as measured by the optical
density at 395 nm. The reduced form was apparently stable, although
inconclusive evidence suggested that some additional breakdown
of RTFM may have occurred within 3 mo. under anoxic conditions,
no significant degradation of TFM was observed for periods of
up to 2.5 mo. Sorption of TFM by sediments was observed to some
extent and appeared to vary with the sediment source.

HAPAB Reduction of TFM to 3-trifluoromethyl-4-aminophenol (RTFM)
by trout liver homogenates was approximately linear over a 2-hr
period and was greatly stimulated by the addition of FAD. Omission
of NADP SUP+ and FAD from liver or kidney homogenates reduced
activity, but omission of glucose-6-phosphate, glucose-6-phosphate
dehydrogenase, and niacinamide had little or no effect. Liver
activity was about eight times that of kidney. RTFM was acetylated
by liver and kidney extracts when acetyl-CoA was added to the
mixture. In vitro formation of TFM glucuronide was demonstrated
utilizing liver extracts, UDPGA, and saccharo-1,4-lactone. Glucuronidation
in vitro occurred at a rate 10 times that of reduction. Exposure
of trout to (SUP)14C-TFM consistently resulted in only one metabolite,
TFM glucuronide.

Metabolism
Of 3-Trifluoromethyl-4-nitrophenol In
The Rat
Lech JJ
The biotransformation and excretion of 3-trifluoromethyl-4-nitrophenol
(54660) (TFM) were studied in Holtzman-rats. In various studies,
groups of rats were injected intraperitoneally with radiolabeled
TFM at 12 milligrams per kilogram (mg/kg) or non labeled TFM
at 18mg/kg. Metabolites were extracted from pooled urine which
had been collected over 24 hours. They were isolated, characterized,
and identified using thin layer and gas liquid chromatography
and absorption spectrophotometry. About 60 percent of the injected
radioactivity was recovered in the urine. TFM and a metabolite,
the reduction product of 3-trifluoromethyl-4-aminophenol (RTFM),
were identified in urine extracts, along with a small amount
of free unchanged TFM. Most of the excreted TFM, as well as
the RTFM, were polar derivative acid labile compounds yielding
to acid hydrolysis by beta-glucuronidase. The
author concludes that the major metabolite of TFM is its reduction
product RTFM, and that both TFM and RTFM are excreted largely
as polar derivatives.
