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 weights were obs

1989. 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 HF liquid rati [abstract truncated]

An evaluation was made of possible long term exposure to potroom gases, fumes, and dusts at Ormet Corporation (SIC-3334), Hannibal, 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 there was a potential for excess exposu [abstract truncated]

1989. Health Assessment for Alsco Anaconda National Priorities List (NPL) Site, Gnadenhutten, Ohio, Region 5

CERCLIS No. OHD057243610.

Agency for Toxic Substances and Disease Registry, Atlanta, GA.

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.

CERCLIS No. WAD000065508.

Agency for Toxic Substances and Disease Registry, Atlanta, GA.

The 240-acre Kaiser Aluminum Site is on the National Priorities List. The plant was built in 1942 as an aluminum reduction facility. Concentrations of cyanide (total) in the river range from 0.011 to 1.7 parts per million (ppm) and free cyanide concentrations ranged from non-detected (ND) to 0.58 ppm. Soils on-site are contaminated with cyanide and fluoride; total cyanide levels range from ND to 985 ppm. 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 ingestion of contaminated groundwater, dermal absorption of contaminants found in the surface soils on-site, and inhalation of and dermal contact with reentrained contaminated dust.

1989. 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.

This report is one of several work products generated by the Industry Cooperative HF Mitigationssessment Program. This ad hoc industry program began in late 1987 to study and test techniques for mitigating accidental releases of hydrogen fluoride (HF) and alkylation unit acid (AUA) and to better estimate ambient impacts from such releases. The hazards of HF have long been recognized. Standard operating practices focused on minimizing the possibility of a release and mitigating the effects if a release should occur. These practices are continually monitored and improved to maximize safety protection based on the available technical data. This recent program targeted further improvements based on new technical data.

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 f [abstract truncated]

Author: Kierdorf U

Cologne Univ. (Germany, F.R.). Mathematisch-Naturwissenschaftliche Fakultaet.

An anomaly found in the permanent teeth of deer (Capreolus capreolus L.) was investigated as to its generation and distribution. The 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 contaminated environment because of several protective mechanisms be [abstract truncated]

Syracuse Research Corp., NY.
Environmental Monitoring and Services, Inc., Washington, DC.

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 there are no dose groups where the incidence is less than 100 percen [abstract truncated]

The studies covered the following problems: an influence of some environmental agents on the mutagenic effectiveness of ionizing radiation, 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 dibromomethane. It was also discovered that in the range of low doses the effect was proportional to radiation dose and total exposition [abstract truncated]

The primary objective of the study was to evaluate atmospheric dry deposition of major anions and cations to trees in the Emerald Lake area of Sequoia National Park. The field work was performed between July 15 and September 10, 1987. Teflon-coated and non-coated branches of native lodgepole pine (Pinus concorta) and western white pine (P. monticola), and potted seedlings of Coulter pine (P. coulteri) were rinsed using deionized-distilled water. Nylon 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.
