Agency: Industrial Environmental Research
Lab., Research Triangle Park, NC. |
The report
gives results of a phosphate fertilizer
industry study to evaluate multimedia control technology,
identify information gaps, and define needed RDandD projects.
The following manufacturing processes were covered: wet process
phosphoric acid, superphosphoric acid, diammonium phosphate,
and normal and triple superphosphate. Air emission control technology,
based largely on using wet scrubbers, is
adequate for control of fluoride and particulate and
is used throughout the industry. The cross-flow packed scrubber
appears to be the best and applies to all processes. The
gypsum pond appears to be the major environmental concern: main
problems are fluoride emissions to the atmosphere and possible
leaching of fluoride, phosphate, and radioactive substances.
None of the several control alternatives are economically attractive.
RDandD projects identified and defined in this study are: (1)
an epidemiologic study of the industry; (2) studies of gypsum
pond emissions and chemistry; (3) an evaluatio [abstract truncated] |

Drinking-Water Quality and Variations in Water Levels in the
Fractured Crystalline-Rock Aquifer, West-Central Jefferson
County, Colorado
Authors:
Hall DC

Geological
Survey, Lakewood, CO. Water Resources Div. |
In
parts of the area, water for domestic use obtained from the
fractured crystalline-rock aquifer contained excessive concentrations
of dissolved fluoride, dissolved
nitrite plus nitrate, dissolved solids, dissolved iron, dissolved
manganese, dissolved zinc, coliform bacteria, gross alpha radiation,
and gross beta radiation. Based on water-quality analyses from
26 wells located in small urbanized areas, water from 21 of
the wells contained excessive concentrations of one or more
constituents. Local variations in concentrations of 15 chemical
constituents, specific conductance, and water temperature were
statistically significant. Depths to water in 11 non-pumping
wells ranged from 1 to 15 feet annually. Three-year trends in
water-level changes in 6 of the 11 wells indicated a decrease
in stored water in the aquifer. Water-resources investigations

Resour. Div., Geol. Surv., Rolla, MO |
Water in
Center Creek basin upstream from the proposed Prosperity Reservoir
dam site is a calcium bicarbonate type that is moderately mineralized,
hard, and slightly alkaline. Ammonia and organic nitrogen, phosphorus,
total organic carbon, chemical oxygen demand, and bacteria increased
considerably during storm runoff, probably due to livestock
wastes. Nitrogen and phosphorus concentrations are probably
high enough to cause the proposed lake to be eutrophic. Minor-element
concentrations were at or near background levels in the dissolved,
total, and bottom phases. The only pesticides detected were
0.01 mug/l of 2,4,5-T in one base-flow sample and 0.02-0.04
mug/l of 2,4,5-T and 2,4-D in all storm-runoff samples. Fecal
coliform and fecal streptococcus densities ranged from 2-650
and 2-550 colonies/100 ml, respectively, during base flow, but
were 17,000-45,000 and 27,000-70,000 colonies/100 ml, respectively,
during storm runoff. Water in Center Creek about 2.5 miles downstream
from the proposed dam site is similar in quality to that upstream
from the dam site except for higher concentrations
of sodium, sulfate, chloride, fluoride, nitrogen, and phosphorus.
These higher concentrations are caused by fertilizer industry
wastes that enter Center Creek about 1.0 mile downstream from
the proposed dam site. |

Rats were
subjected to whole body HF exposure for 6 hrs or to nose-only
HF exposure for 1 hr. Total and/or ionic fluoride concentrations
in selected tissues were determined at various times following
exposure. In rats sacrificed 6 hrs after whole body exposure,
dose-dependent increases in lung, plasma, and kidney total and
ionic fluoride concentration occurred. Rats excreted more fluoride
in the urine after whole body exposure than could be explained
by the amount of HF inhaled. Considerable evidence suggests
that airborne HF deposits on fur and is then ingested due to
preening activity. Urinary fluoride excretion
was increased by nose-only exposure. The urinary fluoride excretion
accounted for approximately twice the fluoride estimated to
be inhaled during exposure. Tissue fluoride concentrations
were elevated immediately after nose-only exposure. Fluoride
concentrations in lung and kidney returned to control levels
within 12 hrs. Plasma fluoride concentration was slightly elevated

gas centrifuges is discussed. The maximum permissible mass and
curie concentration of airborne uranium (U) is identified as
a function of the enrichment level (i.e., U-235/total U), and
chemical and physical form. A discussion of the chemical and
radiological toxicity of uranium as a function of enrichment
and chemical form is included. The toxicity of products of UF
sub 6 hydrolysis in the atmosphere, namely, UO sub 2 F sub 2
and HF, the particle size of toxic particulate material produced
from this hydrolysis, and the toxic effects
of HF and other potential fluoride compounds are also discussed.

were all well within the most recent evaluation criteria. An
overexposure to fluoride existed in one of the five workers
monitored for fluoride. Seven Cr+6 samples were taken
in the general area and in the breathing zone of welders welding
stainless steel. All levels were below the NIOSH laboratory
limits of detection (.005 mg/sample). All workers were interviewed
pre- and post-shift by a NIOSH medical team. Based on data collected,
workers did not have medical problems. Based on industrial hygiene
data, the only hazard existing at the

Expected Fluoride Contaminant Loading Within Expanded North
Boundary Control System.
Author:
Campbell DL
Army
Toxic and Hazardous Materials Agency, Aberdeen Proving Ground,
MD. |
Geotechnical
surveys have been recently completed in the North Boundary Vicinity
of Rocky Mountain Arsenal to define the arsenal's subsurface
hydrogeology. Water table measurements and permeability estimates
have been generated to refine flow direction and quantify ground
water movement of the alluvial aquifer as it flows across the
North Boundary. This document presents
a compilation of data assessments based upon the aforementioned
survey results on expected fluoride contaminant loading with
the proposed expanded North Boundary control system. As
a result of these assessments, it has been determined that there
is a good possibility that fluoride levels within the expanded
treatment subsystem will be naturally below the state of Colorado
limit, this may negate the need to add a costly fluoride removal
module to the proposed granular carbon organic removal process.

Test Plan for Pilot Test Program for Removal of Excess Fluoride
from Activated Carbon Effluent.
Rubel
and Hager, Inc.,
Tucson, AZ. |
In accordance
with a directive from the Colorado Department of Health, the
reinjection water at the north boundary of RMA will be subject
to drinking water standards established by EPA and CDH. In response
to this directive, Rubel and Hager engaged to perform a feasibility
study during September 1978. The results documented that using
the activated alumina treatment method, the
excess fluoride can be removed from the carbon treated water
at the reinjection site. At the conclusion of the feasibility
study, it was determined that further pilot testing would be
necessary to optimize the caustic regeneration procedure for
maximum long-term economy. Therefore, this pilot test program
has been established. Under this program the following tasks
will be: (1) to determine whether there are any interferences
present in the activated carbon effluent that may reduce the
efficiency of the process, (2) an optimum alumina regeneration
process will be developed to minimize operating costs. |

The first
undertaking of the Safe Drinking Water Committee of the National
Academy of Sciences was the identification of substances and
their concentrations in the nation's water supply that might
pose risks to the public health. This report, on the other hand,
identifies and discusses substances found in drinking water
which may have nutritional significance. The substances addressed
include calcium, magnesium, phosphorus, fluoride, sodium, potassium,
chloride, iodine, iron, copper, zinc, selenium, manganese, arsenic,
nickel, vanadium, silicon, molybdenum, and chromium. For each
substance, data on occurrence in food and water are reviewed,
nutritional requirements, toxicity versus essential levels,
and the contribution from drinking water are assessed. Recommendations
are made regarding the appropriateness of controlling these
substances in drinking water. |

The
Clean Air Act Amendments of 1977 require that the USEPA consider
specific criteria in determining priorities for setting NSPS
for major source categories: quantity of air pollutant emissions,
extent to which air pollutant emissions endanger public health
and welfare and the mobility and competitive nature of each
source category. A previous report (EPA-450/3-78-019) describes
a methodology that has been developed for prioritizing source
categories using the Clean Air Act criteria. The methodology,
which employs three distinct computer programs, was applied
to a data set of over 150 major source categories for nine different
air pollutant emissions (particulate matter, sulfur dioxide,
nitrogen oxides, hydrocarbons, carbon monoxide, lead, sulfuric
acid mist, hydrogen sulfide, and fluorides).
The program output is a prioritized list of source categories
for NSPS promulgation over a ten year period based on a multipollutant

than at a companion commercial facility at Buhl, Idaho, but
was attributed to facility differences rather than an adverse
impact of geothermal water. No significant differences were
recorded between Raft River and Buhl fish for bone calcium or

the concentrations of airborne plutonium at perimeter and community
locations were identical and were within the range attributed
primarily to fallout from atmospheric nuclear weapons testing.
The sanitary water was processed through a tertiary treatment
facility before discharge, and the discharges were monitored
for compliance with the Plant's National Pollutant Discharge

The goal
of the Rocky Mountain Arsenal (RMA) northwest area effort was
to evaluate groundwater pollution of the near surface aquifer
in this area of the Arsenal. To accomplish this goal, sufficient
additional geological, hydrological, and water chemistry data
was collected to interpret existing information and provide
data from parts of the study area where little or no data previously
existed. Soil samples were collected to provide geological and
hydrological information. Well water samples were drawn to determine
groundwater chemistry. The most significant
water constituents were DIMP, DCPD, DBCP (Nemagon), and
fluoride. Similar geological and hydrological results
were obtained as previously mentioned. Fluoride
levels exceeding the acceptable standard appeared to be crossing
the northwest Arsenal boundary. High DIMP concentrations
were observed in an area generally northwest of the northwest
part of Basin F. The existence of DCPD could not be established

Evaluation of RMA Fluoride Data.
Rocky

Denver, CO. |
In
summary, it was concluded that: Fluoride concentrations for
15 out of 18 360 deg monitoring wells in the vicinity of the
north boundary, northwest boundary, and north side of Basin
F at RMA are averaging above the State of Colorado standard
of 2.4 mg/1. The evaluation of this data has resulted in a range
of levels between 0.763 and 7.462 mg/l.
At the north boundary in the vicinity of the pilot containment/treatment
system, fluoride levels average approximately
3.5 mg/l. Evaluation of the data for seasonal trends
over a two-year period 75127 (1 Jun 75) to 77003 (1 Jan 77)
yielded inconclusive results. Limited success was realized in
the determination of temporal trends. Several
wells in the vicinity of Basin F show consistent decrease of
fluoride concentration with time (approximately 0.5 mg/l per
year). |

fluoride content of the waters were low and would not account
for the tooth lesions. Possible reasons for lack of correlation
are changing of the composition of the water, other sources

Monitors
for selected organic and inorganic gaseous hazards were developed.
Initially the goal was to develop personal monitors utilizing

toluene (108883), inorganic gases, hydrogen-fluoride
(7664-39-3), and hydrogen-sulfide (7783064) were presented.
Studies have substantiated the applicability of the permeation
approach for monitoring benzene, toluene, trichloroethylene
(79016), methylene-chloride (75092), chloroform (67663), and
carbon-tetrachloride (56235). Laboratory and field tests have

This handbook
explains the effects of various air pollutants on vegetation
and how to diagnose the suspected injuries. It discusses the
structure and function of plants in relation to air pollution
injury and the different pollutants: photochemical oxidants,
sulfur dioxide, fluorides, and
minor pollutants. It also explains the interactions between
pollutants and pollutants and pathogens, discusses mimicking
symptoms, and identifies the sources and meteorological aspects
of air pollution and the effects of topography on dispersion.
The basic procedure and routine for diagnosis of suspected air
pollution injury to vegetation is outlines. Charts, glossary
and index are included. |

Draft Environmental Statement: The Alumax Environmental Statement.
Bonneville
Power Administration, Portland, OR. |
BPA proposed
to serve the planned Alumax plant near Umatilla with ''Industrial
Firm'' power, the same grade of power now being purchased by
the other industrial customers served directly by BPA. The contract
amount of power is 320 megawatts. This would involve construction
and operation of the Alumax-Pacific Corporation, primary aluminum
reduction plant and associated transmission and substation facilities,
near Umatilla, Oregon. Construction and
operation of the proposed facilities would result in degradation
of air quality as related to particulates, sulfur oxides and
fluorides. Increased population in adjacent local communities
would require significant amounts of new land development, cause
overcrowding in certain school districts, and further burden
regional water systems. The increased tax base will allow for
mitigation of these problems. 260 refs., 35 figs., 121 tabs.

Inst. for Occupational Safety and Health, Cincinnati, |
Attempts
were made to characterize the response of laboratory animals
to particulates carried in the air and to gaseous airborne
pollutants, as a preliminary step towards investigation of
the effects of a mixture of gaseous and particulate pollutants.
Guinea pigs were exposed to fluoride
at 1.2mg/m3 as fluorspar dust of respirable size for 16 weeks,
or to fluoride at 3.3mg/m3 as hydrogen-fluoride. The fluoride
concentrations were increased in plasma, femur, and feces.
Hydrogen-fluoride exposure also increased fluoride levels
in the bile and urine. The number of alveolar macrophages
was increased on dust exposure whereas the incidence of patchy
pneumonitis was decreased on hydrogen-fluoride exposure.
All these changes returned to normal after exposure to the
fluoride agents was terminated, with
the exception of skeletal fluoride levels. No evidence
of continuing harmful effects was noted. |

Sample preparation and ashing procedures are described. Data
on recovery rates from spiked samples is included. The method
was unsatisfactory due to poor recovery rates and an unacceptably

Working
conditions were surveyed at the Alcoa Company (SIC-3295) in
Alcoa, Tennessee on May 23, 1977. The company employed 1,100
people. Production ran continuously on a three shifts per day
basis. Potential hazards observed were
exposure to fluorides, particulate polycyclic organic
matter, heat, airborne dust and carbon-monoxide (630080). Areas
of exposure included the potroom and carbon plant. The author
concludes that exposure to environmental contaminants was very
low due to extensive control systems, new equipment and automation.

As part
of a larger study of exposures in the phosphate
industry, a survey was conducted at CF Chemicals, Inc., located
in Bartow, Florida. At the facility there were eight
major sections monitored: sulfuric-acid facility, phosphorus-acid
facility, acidulation facility, three diammonium-phosphate facilities,
two product storage areas, two shipping areas, operations and
staff office, and quality control laboratory. The major products
were diammonium-phosphate and dicalcium-phosphate. Periodic
sampling was performed for sulfur-dioxide (7446095),
noise levels, ammonia (7664417), and fluoride.
The ventilation systems were designed primarily for emission
control and appeared to be adequate. With the exception of two
samples for fluorides and three samples of chromium (7440473),
the emissions were within the levels recommended. The authors
recommend the use of tank entry procedures and personal protective
equipment. |

A health
hazard investigation of exposure to solvents was conducted by
NIOSH on March 2-3, 1977 at the Airtex Products plant in Fairfield,
Illinois, a facility engaged in the manufacture of automobile
replacement parts. Environmental air samples, employee interviews,
evaluation of ventilation systems, and available toxicity information
resulted in the conclusion that exposures to monochlorobenzene
(108907), isopropyl alcohol (67630), methyl ethyl ketone (78933),
toluene (108883), trichloroethylene (79016), sodium hydroxide
(1310732), phosgene (75445), zinc oxide, cadmium (7440439),
fluorides, hydrochloric acid (7647010), and oil mist did not
pose a health hazard at the concentrations measured at the time
of evaluation. It is felt that the cause of the problems (such
as nausea, dizziness, headaches, breathing difficulties, nose
bleeds, etc.) at Airtex is a multifactorial one, involving an
inefficient ventilation system which, combined with the employees'
lack of information about the materials th [abstract truncated] |

A preliminary
industrial hygiene survey was conducted at the Kaiser
Aluminum Company, Chemical Division, Gramercy, Louisiana,
to determine whether to include this facility in an epidemiological
study of workers exposed to carbon-tetrachloride (56235). At
the facility the following products were manufactured: alumina,
chlorine, caustic, refrigerants, hydrogen-fluoride,
aluminum-fluoride, and calci-coke (a high grade carbon).
Raw materials used and possible contaminants
included not only carbon-tetrachloride, but also hydrochloric-acid
(7647010), ammonium-chloride (12125029), chloroform (67663),
hydrogen-fluoride (7664-39-3),
antimony-chloride (10025191), and caustic. An
industrial hygienist was located at the facility and personal
and area air samples were taken regularly in some potentially
hazardous areas. A full time nurse was located at the
site. Preemployment and periodic physical examinations were
required of all workers. The primary potential health hazards
existing at the site were related [abstract truncated] |

27-29, 1977, at the Kaiser Aluminum and Chemical Corporation,
Ravenswood, West Virginia in the facility for the production
of virgin aluminum metal by electrolytic reduction of alumina
(1344281) using prebaked carbon electrodes and cryolite (1344758)
flux. Environmental sampling revealed that the anode setters
in the pot area may be exposed to excessive concentrations of
aluminum oxide (1344281), while fluoride
exposure was not excessive. In the casting area exposure
to carbon monoxide (630080), sulfur dioxide (7446095) and ammonia
(7664417) was minimal. According to available medical data,
the findings related to determining whether a high rate of coronary
disease existed were inconclusive. Recommendations are made
for environmental control and medical surveillance of employees.

An industrial
hygiene survey was conducted at the Stauffer Chemical Company,
Salt Lake City, Utah on July 16-25, 1975 as part of a study
of variations in worker exposures in different wet chemical
operations. The operation evaluated was the cleaning of a large
phosphoric acid reactor vessel. Samples taken for an 8-hour
time weighted average exposures for cadmium, chromium, canadium,
phosphoric acid, and sulfuric acid on workers involved in the
cleaning. General area samples were collected
for fluorides, radon, particle size distribution and
uranium. All contaminants were below the current legal standard,
but there was an irritating material present in the tank environment.
It is recommended that the good work practices for tank entry
be continued. The radiation levels were very low which would
have made this facility ideal for determining if exposure to
phosphoric acid results in an increased incidence of cancer,
but medical and personnel records were not adequate. |
