Halocarbon
27-S (HC 27-S), a polymer of chlorotrifluoroethylene (CTFE),
is used as a lubricating oil for pumps in hyperbaric chambers.
Although monomeric CTFE has been shown to produce renal lesions
in rats, the toxicity of CTFE polymers has not been investigated.
Following a single dose of 5 g HC 27-S, no signs of toxicity
were noted and no lesions observed at sacrifice 14 days following
treatment. To assess the toxicity of repeated exposure to HC
27-S, three groups (n=5) of male and female rats were dosed
with 2.5 g HC 27-S/kg for 7 or 21 consecutive days. Groups were
sacrificed at 7, 21, and 35 days after the initial dose. Decreased
water consumption and urine output were apparent in all test
groups. Significant increase in fluoride
excretion was noted in 24-hr urine samples collected periodically
during the study. The increased fluoride burden in treated animals
appeared sufficient to alter bone calcium/phosphate ratios in
male but not female rats. Increased liver and kidney

Effectiveness
of water spray mitigation systems for accidental releases
of hydrogen fluoride. Volume 1, Detailed report.
Industry
Cooperative Hydrogen Fluoride Mitigationssessment Program.
Water Spray Subcommittee. |
Accidental
releases of Hydrogen Flouride (HF) can result in initally dense,
highly reactive and corrosive clouds. These
clouds will typically contain a mixture of HF vapor, aerosol
and droplets which can be transported significant distances
downwind before lower hazard levels of HF concentration
are reached. Previous experiments were performed to study atmospheric
dispersion of these HF clouds. The present study examines the
effect of water application on the mitigation of these clouds.
To assess the effectiveness of water application (via either
sprays or monitor) in mitigating HF clouds two series of tests
were conducted in separate flow chambers. Bench scale experiments
identified key variables for testing in a larger facility. The
larger scale field tests demonstrated that HF releases can be
mitigated with water. The impact of numerous design variables
on mitigation effectiveness has also been quantified. HF removal
efficiencies of 25 to 90+% have been demonstrated at water to

Ohio. The facility was a producer of primary aluminum,
had six potrooms, each composed of two buildings housing 86
pots, for a total of 1032 pots. Excessive
exposures to fluorides were determined among crane operators,
particularly among cranemen involved with the placement of new
carbon anodes in the pots. Personal samples for fluoride obtained
from these men ranged from 0.95 to 3.61mg/m3. Sixteen
percent of workers completing a medical questionnaire reported
symptoms suggestive of asthma; in 13 of these cases the asthma
was temporally related to work and symptoms worsened in or near
the potroom. Neurologic effects were no more prevalent among
current potroom workers than among other participants in the
medical review. However, each was more prevalent among workers
who had ever worked in the potroom. The report concludes that

The Alsco
Anaconda plant is listed on the National Priorities List. The
soil, sludge, groundwater, and sediment were sampled. On-site
soils are contaminated with manganese at levels of public health
concern, 480-7,200 parts per million (ppm). The swamp sediment
is contaminated with polychlorinated biphenyls (PCBs) (Aroclor
1242, 1248, and 1254) at levels of public health concern, less
than 0.16-3,000 ppm. Groundwater samples show that cyanide (total)
(less than 0.02-0.47 ppm), fluoride (less
than 0.1-8.7 ppm), nitrate (less than 0.1-21 ppm), and
selenium (less than 0.001-0.015 ppm) are at levels of public
health concern. The site is considered to be of potential public
health concern because of the risk to human health caused by
the possibility of exposure to hazardous substances via the
ingestion of contaminated biota found in the swamp and of river
water after the site has been flooded. Preliminary rept. |

Pilot
Plant Makes Oxygen Difluoride: Equipment processes the toxic,
difficult-to-make substance efficiently and safely.
National
Aeronautics and Space Administration, Washington, DC. |
This citation
summarizes a one-page announcement of technology available for
utilization. A pilot plant makes oxygen difluoride, a highly-energetic,
space-storable oxidizer that is not made commercially. The plant
is designed to handle the reactants, product, and byproduct,
most of which are highly reactive, corrosive, and toxic. The
plant fluorinates aqueous alkali to produce OF2 in the reaction
of 2F2 + 2KOH to OF2 + 2KF + H2O. The undesired reaction 2F2
+ 4KOH to O2 + 4KF + H2O also consumes about half of the fluorine.
The concentration of the KOH must be maintained at 2%, and the
KOH solution must be kept cold. Because the potassium fluoride
byproduct is toxic, it is treated with calcium hydroxide: 2KF
+ Ca(OH)2 -> CaF2 + 2KOH. The calcium fluoride precipitate
is nontoxic and can be discarded safely. The potassium hydroxide
is recycled to the solution. NTIS Tech Note. |

The
document on the subject of inorganic fluorides contains data
concerning their sources and distribution pattern (soil, water,
air, biota),
the risks based on a careful consideration of exposure levels
and toxic concentrations, the technical possibilities of reducing
these risks and the economic consequences of any measures taken
or proposed. The information provides the scientific basis for
the formulation of the effect-directed standardization policy.
Further study of the inorganic fluorides is called for because,
for the time being, the extent and scale of their effects on
public health, ecosystems, cultivated plants and livestock are
not sufficiently well known. The extent
to which fluoride accumulates and causes more problems in the
long term is also not sufficiently clear. See also PB90-210261. |

The
average daily hydrogen fluoride intake is on the order of 1.2-3.0
mg/day from food and water, respectively. For
children and adults who do not have any occupational exposure
to or do not live in the immediate vicinity of industrial operations
that emit HF. Use of fluoridated dentifrices contributes an
additional 0.25 mg/day; less than 0.1 mg/day comes from inhaled
fluoride. This total exposure level (approximately 0.06 mg/kg/day)
has been shown to have a cariostatic effect, especially in children,
and is generally considered to be the No Observed Adverse Effect
Level (NOAEL). This level of exposure has been established as
the oral reference dose (RfD) by the Agency, although it should
be noted that very mild dental fluorosis (mottling) has been
observed in about 20% of the people who are chronically exposed
at this level. The possible carcinogenic potential or chronic
exposure to fluoride has been investigated, and the Agency has
stated that there is not enough information to conclude that

of water spray in mitigating releases of Hydrogen Fluoride (HF).
Bench scale experiments identified key variables for testing
in a larger facility. The larger scale field tests have demonstrated
that HF releases can be mitigated with water and have also quantified
the impact of numerous design variables on mitigation effectiveness.
HF removal efficiencies of 25 to 90+(percent) have been demonstrated
at water to HF liquid ratios of 6/1 to 40/1. 81 refs., 18 figs.,

An anomaly

examined lower jaws stemmed from different regions of the federal
Laender North-Rhine Westphalia and Baden-Wuerttemberg. The
diagnosis made on the basis of the pathomorphological findings
attributed the tooth deformities to dental fluorosis, in other
words, the animals suffered chronic fluoride intoxication during
tooth development. Analyses of the fluoride content of
lower-jaw bones, tooth enamel and dentine from afflicted deer
and non-afflicted animals confirmed this assumption. Radiological
investigations as to the crown development of permanent molar
teeth of deer permitted to formulate a hypothesis regarding
the varying degree of deformation sustained by the teeth in
the event of dental fluorosis. Both the fetus and fawn are assumed
to be largely protected from intoxication even in a severely

Beryllium
is a probable human carcinogen, classified as weight-of-evidence
Group B2 under the EPA Guidelines for Carcinogen Risk Assessment.
Evidence on potential carcinogenicity from animal studies is
'Sufficient,' and the evidence from human studies is 'Inadequate.'
It is considered highly likely that all soluble forms of beryllium
including beryllium chloride, beryllium, fluoride and beryllium
nitrate are carcinogenic in animals. These three soluble beryllium
compounds are therefore assigned to weight of evidence Group
B2. The potency factor (F) for beryllium is estimated to be
79.70 (mg/kg/day)(-1), placing it in potency group 2 according
to the CAG's methodology for evaluating potential carcinogens.
The bioassay used to calculate the potency
factor for beryllium chloride, beryllium fluoride and beryllium
nitrate suggests that these substances are highly carcinogenic
(i.e., all treated animals developed tumors), but because

interaction between ionizing radiation and chemical mutagens
in the induction of somatic mutations and also an application
of Tradescantia model system for biological monitoring. The
studies showed that the pretreatment of Tradescantia
plants with sodium fluoride or the modification of the soil
composition with dolomite admixture, visibly influences plants
radiosensitivity. The analysis of the changes in the dose-response
curves suggested that the employed agents were influencing in
different ways the repair processes of the DNA. The studies
on the interaction between agents proved that the synergistic
effect occurs in case of combined action of ionizing radiation
with such chemical mutagens as ethyl methansulfonate or 1,2

and paper filters were exposed along with the vegetation, and
were extracted in deionized-distilled water. The rinses and
extracts were analyzed for concentrations of nitrate, sulfate,
phosphate, chloride, fluoride,
ammonium, and metallic cations. The deposition of nitrate to
paper filters and to Coulter pine branches was significantly
higher than deposition to the native conifers. Deposition of
nitrate was significantly greater than deposition of sulfate,
supporting earlier studies of chapparal in the South Coast Air
Basin. Ammonium deposition was [abstract truncated] |

A study
was made of possible worker exposure to metallic oxides or fumes,
refractory (ceramic) fibers, mold coating compounds, and fluxing
agents at Hater Industries (SIC-3341), Cincinnati, Ohio. The
foundry was engaged in the manufacture of a variety of aluminum
automotive and commercial mold castings. Work practices and
conditions of exposure were observed during a walk through survey.
Employee medical interviews were conducted, and medical records
were reviewed. OSHA air monitoring data were reviewed. Transient
symptoms of upper respiratory irritation were reported by molders;
sawmen and hot inspectors did not report respiratory symptoms.
No objective evidence was found of chronic respiratory illness
or metal fume fever in the study population. Heat intolerance
was reported by two molders. Air monitoring data indicated no
overexposures. The authors conclude that no evidence of chronic
respiratory illness could be documented, although acute respiratory
irritation appeared common. The authors r[abstract truncated]
