1983. Identification of the water Quality Factors Which Prevent Fingernail Clams from Recolonizing the Illinois River - Phase 3.

Illinois Natural History Survey, Havana. River Research Lab.

The purpose of this research was to determine why fingernail clams have been unable to recolonize a 100-mile reach of the Illinois River where they were abundant prior to a die-off in the 1950's. Fingernail clams are major links in food chains leading from detritus and algae to higher level consumers valued by man, such as fish and water fowl. Three suspected toxicants--fluoride, lead and cadmium--and sediments from the reach where the die-off occurred were tested on intact fingernail clams (Musculium transversum) and gill preparations isolated from the clams. Results indicate that the sublethal response exhibited by the gills to fluoride is at least four times more sensitive than the lethal response. The results of the gill assay suggest that sediments in the Illinois River contain unidentified toxic factors and that sediments in the upper river, closer to the metropolitan areas of Joliet and Chicago, are more toxic than sediments further downstream.

Atomics International Div., Richland, WA. Rockwell Hanford Operations.

On the afternoon of December 8, 1982, three Rockwell Chemical Technologists, B, D, and E, were transported to Kadlec Hospital with varying degrees of dermatitis and respiratory problems. One chemical technologist was held overnight and released to return to work on December 13, 1982. The other two were not released until December 16, 1982, and continuing ill effects have prevented their return to work. The chemical technologists' symptoms developed initially during a sodium fluoride repackaging operation in Room 4M of the 222-S Analytical Laboratory. The sodium fluoride was being repackaged from a 25-lb box of the material into 500-g quart ice cream cartons. The repackaging was done inside a chemical fume hood. The closed cartons were removed from the hood and sealed with tape on a laboratory bench. Procedurally, the final taping was to be done in the hood. Events and causal factors associated with the incident are summarized. It is concluded that extreme sensitivity of the three individuals to [abstract truncated]



1983. Critical Study of Measurement Methods for Fluoride Emissions to the Atmosphere Used in the Main Fluoride Emitting Industries.

Macken K
Reilly M

Commission of the European Communities, Luxembourg.

Gaseous and particulate emissions containing fluoride arise from the following industries: primary aluminum production, iron and steel making, phosphate processing, clay firing, and glass making. The physical and chemical properties of the emissions are detailed and current legislative requirements in EEC countries and Norway are examined. Methods of sampling emissions and analytical procedures used by the different industries are reviewed with reference to the literature and compared. It is found that isokinetic sampling, using an inert material such as stainless steel for components, is advisable. Analytically, the two main possibilities are the selective ion electrode or a colorimetric method, but preference is given to the former because of its simplicity. An appendix contains the European Primary Aluminium Association's methods and the Norwegian reference method. Final rept.

1983. Measurements of Fluoride Concentration in the Narssaq River in Connection with Tunnel Mining at Kvanefjeld 1979-81.

Author: Soerensen A

Risoe National Lab., Roskilde (Denmark).

The Ilimaussaq intrusion contains the water soluble mineral Villiaumite (NaF). The estimated content is 21 000 ton of NaF (10 000 ton of F). An estimated 175 Ton NaF is transported annually to the Narssaq bay through the Narssaq river. A measurement programme was set up before the tunnel work was begun and the programme was conducted until one year after in order to demonstrate wether the concentration of NaF in the river water was increased by the tunnel work. The concentration was measured periodically up streams and down streams of the working area. It was found that the concentrations in the two points varied greatly over the year. In summertime with high water discharge the concentration was around 2.5 ppm F, whereas in wintertime with low water discharge the concentrations reach values as high as 30 ppm F in both points. However the ratio between the concentrations in the two points was fairly constant through the whole period. This indicates that the tunnel work has not caused any measura [abstract truncated]



1983. Dose-Response Effects of Fluoride in Mammalian Species.

Department of Energy, Washington, DC.

In man and in other species, a number of undesirable effects have been attributed to fluoride. Since most of these have not been investigated systematically in human subjects, it is often unclear to what extent, if any, fluoride is responsible. Proper dose-response information is lacking. A review of the literature describing some of the better investigated effects of fluoride in man indicates that in residents of the United States: (1) growth is unaffected by waterborne fluoride concentrations of 5 mg F/liter; (2) no renal effects are seen at concentrations of 8 mg F/liter; (3) no increase in skeletal density, as detected on x-ray films, is produced by concentrations of 4 mg F/liter; (4) no increase in the incidence of cardiovascular disease is observed at concentrations of 8 mg F/liter. These concentrations, however, cannot be considered as thresholds. (ERA citation 08:057681) 17. annual conference on trace substances in environmental health, Columbia, MO, USA, 13 Jun 1983.

1983. Field Applicable Method to Reduce Dental Emergencies.

Authors: Tinanoff N

Connecticut Univ. Health Center, Farmington. School of Dental Medicine.

Humans, who were regarded as potentially caries active, rinsed twice a day with either acidulated sodium fluoride or stanous flouride mouthrinses, adjusted to 200 ppm F-. There was a small but significant reduction in Total CFU per l saliva in both groups after a year. No differences were found in lactobacilli counts between the 2 mouthrinse groups or longitudinally within the groups. Selective reduction in Streptococcus mutans was found in those subjects rinsing with SnF2. At the end of 1 year, the SnF2 group had less (26 times) fewer S. mutans compared to the baseline. All patients continued to be caries active after one year despite the use of two daily fluoride mouthrinses; however, the subjects rinsing with SnF2 developed approximately half the number of new carious lesions to those subjects rinsing with acidulated NaF. This study did find that SnF2 was an adjunct in decreasing gingival inflammation. The lower frequency of bleeding sites and the corresponding lower mean GI scores in the [abstract truncated]

1983. Fundamental Studies in the Molecular Basis of Laser Induced Retinal Damage.

Author: Lewis A

Cornell Univ., Ithaca, NY.

This research has led to major discoveries in two general areas. First, we have been able to show that there are a series of anionic activators of visual cells. These anionic activators turn on, in the dark, the enzymatic processes which are usually stimulated by light. Among these anionic activators is fluoride, the important additive in dental care. It is possible that our discovery of anionic activators will allow us to modulate visual sensitivity and excitation. A second major advance during the past year has been the development of a staining method which allows the direct observation with light microscopy of actin filaments in rod outer segments. This discovery will now allow us to view these important actin filaments in live cells under physiologically relevant experimental conditions. It will also allow for the development of new methods to probe pathological and damaged conditions in visual photoreceptor cells. The above discoveries will now be described in two separate sections.

1983. Health Assessment for Frit Industries, Humboldt, Iowa, Region 7

CERCLIS No. IAD041103193.

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

The Frit Industries, Inc., plant site is north of Humboldt, Iowa.S. Highway 169 North. The American Agricultural Chemical Company (Agrico) owned and operated a superphosphate fertilizer plant and a sulfuric acid plant on the site from 1954 to 1972. During that time, many complaints of fluoride contamination of soil and vegetation were made against Agrico by neighboring families. Frit Industries, Inc., purchased the Agrico plant in 1974 and started operations in January 1975. Metals of most concern are lead, cadmium, and inorganic fluoride compounds due to potentially higher concentrations. The major pathways identified which may contribute to human exposures at the present time include air (dust in workplace and residences) and soil (potential crop uptake of contaminants) although a potential does exist for groundwater and surface water contamination. There is insufficient information to determine the significance of exposure via the food chain. Final rept.



1983. Toxicology of Monofluorophosphate (MFP).

Smith FA
Hodge HC

Rochester Univ., NY. Dept. of Radiation Biology and Biophysics.

The toxic effects of Na sub 2 PO sub 3 F are attributable to the fluoride ion released by the in vivo hydrolysis of the parent compound. The monofluorophosphate ion appears to play no role. The acute toxicity of Na sub 2 PO sub 3 F is somewhat less than that of NaF, due to the lesser availability of fluoride in the short term from Na sub 2 PO sub 3 F. In the long term, Na sub 2 PO sub 3 F produces virtually the same picture of renal effects and skeletal storage of fluoride as does NaF.

Contract No. 210-81-7102

Effective exposure control technologies used in the petroleum refinery industry were investigated. Seven refinery operations in the United States were visited to obtain design, operating and effectiveness data on engineering controls to reduce or eliminate hazardous exposures, work practices that reduce contact with harmful agents, process or operation monitoring systems that warn of potential or existing hazards, and personal protective equipment that prevent or reduce individual exposures. Specific controls were identified for hydrogen-fluoride alkylation unit exposure, process sampling, hydrogen-sulfide and benzene, toluene, and xylene monitoring systems, oil water separator emissions, benzene loading emissions, equipment maintenance, catalyst dust wet scrubbers, lube oil and wax processing, and construction changes. The authors note that many of the control technologies were implemented for economic, environmental, or fire and explosion hazard reasons, rather than for reasons of employee health and safety. Even so, they are all very effective means for reducing hazardous exposures, and most are already in use throughout the industry. The authors recommend a regular industrywide communication program to enable dissemination of hazard control information, and further detailed studies of control technologies currently in use.

The results of a survey of 12 United States and 2 Japanese primary aluminum (7429905) facilities (SIC-3334) were examined. The U.S. facilities include seven centerwork and two sidework prebake units, and two horizontal and one vertical Soderberg facility. The Japanese sites included one vertical stud Soderberg and one centerwork prebake facility. The control technology currently used for prebake and Soderberg primary aluminum smelting facilities were described, focusing on effective control technologies found in ore handling and storage, green carbon unit, carbon bake unit, anode rodding, and potlines. Specific chemical agents included fluorides in the potrooms, hydrocarbon vapors in the green carbon facility, sulfur-dioxide (7446095), and hydrocarbons in the carbon bake unit, airborne particulates in ore handling, and metal dust and fumes in the rodding room.

1983. Histological Differentiation Among Abiotic Causes of Conifer Needle Necrosis.

Carlson CE
Gilligan CJ

Intermountain Forest and Range Experiment Station, Ogden, UT.

Symptoms induced by phytotoxic gases within conifer needles can be differentiated histological from those caused by other abiotic agents including winter drying, drought, and salt. However, it is not possible to differentiate among symptoms caused by hydrogen fluoride, sulfur dioxide, ethyl mercaptan, and hydrogen sulfide. Phytotoxic gases cause hypertrophy and hyperplasia of vascular parenchyma, endordermis collapse, and intense vascular staining. The other abiotic agents induce mesophyll collapse with little or no observable effects on vascular tissues. Histological analysis should be useful in diagnosis of air pollution-induced injury and damage in coniferous forests. Forest Service research paper,

1983. MPC(Maximum Permissible Concentrations) for Routine Operations in Diesel Submarines,

Author: Shea M

Naval Submarine Medical Research Lab., Groton, CT.

In 1976, the NATO Naval Medical Working Party drafted an agreement (STANAG 1206) concerning design criteria for atmospheric control in conventional diesel powered submarines. The agreement was intended to establish maximum allowable limits for shipboard atmospheric substances which could pose a health threat to the crew. A list of 22 substances and their proposed limits for a two-day continuous exposure at a normal operating pressure of 1 BAR were attached to the STANAG in Annex A. The bottom line of the agreement was that participating nations would agree to maintain those limits and also agree to design submarines that would not exceed the limits. This paper briefly describes each substance in relation to its health effects and proposed design limits: ammonia, arsine, carbon dioxide, carbon monoxide, refrigerant F-12, hydrogen chloride, hydrogen fluoride, mercury, chlorine, methanal, nitrogen, dioxide, ozone, phosgene, stibine, sulfur dioxide, tri-ortho-cresyl phosphate, and methyl chloroform.

The phytotoxicity of short exposures of gaseous hydrogen fluoride (HF) and of drenches of JP4 jet fuel were examined. Germination and growth of radish and tomato seeds were reduced when planting was delayed one or six hours after 20-minute exposures of the seeds to HF gas. Tomato seeds were more sensitive than radish. Barley, bean, and zinnia plants were exposed once to HF gas when six to 28 days old. Sensitivity of barley plants to injury from HF increased with age; beans were most sensitive when six or eight days old; zinnia sensitivity was not significantly affected by age at exposure. Plants were all harvested when 35 days old; weight and other biomass measures correlated well with plant age at exposure. Plants exposed at an early age never developed well, whereas plants exposed when older were not greatly reduced. Annual rept. 1 Jul 81-31 Jul 82,

Subchronic toxicity was evaluated in groups of 10 male CD rats and 10 male Syrian hamsters exposed by inhalation to 0, 101, 500, 991, or 2489 ppm tetrafluoroethylene (referred to as TFE, 99.3% minimum purity) 6 hrs/day, 5 days/week for 2 weeks. No clinical signs of toxicity resulting from TFE exposures were observed in rats and hamsters during the treatment period. After termination of exposure, rats exhibited a statistically significant decrease in serum albumin and albumin/globulin ratios at all exposure levels, although the effect was not dose related. Urinary fluoride in rats was elevated in a dose dependent manner at all levels, but differences were only significant in the 500,991 and 2489 ppm exposure groups. Other differences noted in rats included significant and dose dependent decreases in serum glutamic-pyruvic transaminase activity and urea nitrogen levels at the 500, 991 and 2489 ppm dose levels. Additionally, rats showed a significant depression in serum alkaline phosphatase activity in the 2489 ppm group. After 14 days of recovery all effects had disappeared in rats, except elevation of urinary fluoride. After termination of exposure, hamsters exhibited a significant increase in urinary fluoride excretion in the 991 and 2489 ppm groups. Serum albumin depression was significant in the 101 ppm exposure group. After the 14 day recovery period serum albumin depression was significant in the 500,991, and 2489 ppm exposure groups; urinary fluoride was at normal levels. Following 10 exposures, 5 of 5 rats exposed at the 2489 ppm level exhibited compound related kidney histopathology which disappeared after 14 days of recovery. No histopathological effects were observed in hamsters after 10 exposures, however, following the 14 day recovery period a significant increase in testicular atrophy was observed in the 2489 exposure group. Rats showed significant elevation of absolute and relative weights of liver and kidneys following the 10th exposure in the 991 and 2489 ppm exposure groups. These effects were not present after the 14 day recovery period. There were no significant differences in absolute or relative organ weights in hamsters exposed to any level of TFE.

On January 22, 1981, a walk-through survey was performed to evaluate the exposures of approximately 24 employees to phenol (Fluid Catalytic Cracking Unit No. 1291) and hydrogen fluoride (Alkylation Unit No. 491). The NIOSH evaluation of employee exposures was based on a review of results of early January 1981, Gulf Oil Corporation environmental monitoring for phenol and hydrofluoric acid (HF), responses from directed questionnaires administered to 24 employees on two of the four shifts in FCCU-1291 and AU-491. One worker, reported to have had a severe allergic reaction, was interviewed by telephone. Based on the results of the environmental/medical evaluation, NIOSH investigators determined that a potential health hazard did not routinely exist for Fluid Catalytic Cracking Unitlkylation Unit employees from exposures to phenol and hydrogen fluoride. However, occasional episodes involving the release of HF have resulted in eye, nose, and throat irritation in a substantial percentage of the exposed [abstract truncated]

1982. Control Technology Assessment of Petroleum Refinery Operations: Indepth Site Visit Report, Sigmor Three Rivers Refinery.

Radian Corp., Salt Lake City, UT.

Examples of good employee exposure control techniques associated with petroleum refining operations were identified. A visit was made to Sigmor's Three Rivers Refinery (SIC-2911) located at Three Rivers, Texas. The exposure controls studied were the hydrogen-fluoride (HF) alkylation unit change room, the HF alkylation unit separate maintenance facilities, and the HF alkylation unit emergency shower booths. Its design included separate facilities to prevent accidental HF exposure to maintenance personnel at the central shops due to inadvertent handling of contaminated equipment from the HF unit. The shower facilities included three showers to decontaminate anyone who had been sprayed with HF acid. When the showers were entered, an alarm automatically notified a central control room of their use. At least a 30 minute supply of tempered water became available for HF acid wash down.

National Inst. for Occupational Safety and Health, Cincinnati, OH.

A target investigation was conducted to determine adverse health effects of inhalation contaminants produced during welding processes. The immediate effects of acute exposure to welding fumes are metal fume fever and eye and throat irritation from ozone (10028156), nitrous oxides, and fluorides. A death certificate survey showed a higher risk of lung cancer death among welders, operators, boilermakers, painters, and oilfield workers. Hardfacing operations resulted in overexposures to inorganic nickel (7440020), hexavalent chromium (7440473), and nitrogen-dioxide (10102440). Shielded metal arc welding or gas welding were used in 82 percent of mine welding operations. Most welding was done on mild and low alloy steels. Most worker complaints resulted from lack of adequate ventilation; few underground welding shops were used, most underground operations were limited to repairs, except for installation of new machinery. Underground welding was always kept to a minimum. Samples were collected in buck [abstract truncated]

National Inst. for Water Research, Pretoria (South Africa).

This study forms part of the NIWR's series of interlaboratory comparison studies involving southern African laboratories engaged in water and wastewater analysis, and is concerned with the analysis of synthetic water samples by 31 laboratories for boron, silica, fluoride, methylene blue active substances (MBAS), phenols, cyanide and sulphide. The results obtained are evaluated and discussed. Recognised standard methods, or modifications of these methods, were used for most of the determinations. Results from the boron, silica and fluoride determinations showed, in general, acceptable accuracy and precision. Results from the MBAS, phenols, cyanide and sulphide determinations were, however, somewhat widespread, and illustrated the difficulty in obtaining reliable results from the measurement of relatively low levels of these determinands.

A walk through survey and a followup on/site environmental and medical evaluation of potentially exposed workers were carried out at Hill Air Force Base (SIC-9711), Ogden, Utah. Followup on/site environmental and medical evaluations of potentially exposed workers were conducted at Koldaire, Inc., Salt Lake City, Utah. Past medical records at Hill Air Force Base and historical worker exposure information were deemed adequate to reconstruct probable exposures to hazardous materials during the performance of various work assignments at the base and to permit a morbidity study to be conducted. Possible exposures in this area of work include fluorocarbons, phosgene (75445), hydrogen -chloride (7647010), hydrogen-fluoride (7664-39-3), welding fumes and cadmium (7440439). It was recommended that respirators be worn by refrigeration repairmen, that medical surveillance be performed yearly, and that eye protection be worn during welding and soldering operations.

In July 1980, NIOSH received a request to evaluate exposures to toluene, xylene, acetone, benzene, lead, hydrogen fluoride, aliphatic hydrocarbons, and other toxic substances at the Phillips Petroleum Company Refinery, Woods Cross, Utah. NIOSH determined that a health hazard existed from exposure to varied petroleum products, solvents and/or gasoline. The case of aplastic anemia suggests that past respiratory protection practices were not adequate. No lasting ill effects from HF exposure are anticipated. [abstract truncated]

The flue gas desulfurization system at Montana Power Company Colstrip Unit 2 was characterized by field testing and engineering analysis. The characterization included measurement of currently regulated as well as unregulated emissions in the gas, liquid, and solid effluent streams of the sulfur dioxide scrubber system. Sulfur dioxide, nitrogen oxides, particulate, fine particulate, trace elements, particle size-segregated trace element distribution, sulfuric acid mist, chlorides, fluorides, organics, carbon monoxide, and carbon dioxide were all measured in the scrubber system influent and effluent streams. In addition, mist eliminator performance, scrubber generated particulate, and scrubber sludge characterization testing and analyses were performed. A significant part of the program was devoted to establishing the applicability of measurement techniques and the quality and limitations of the resultant data. A discussion of the scrubber process chemistry based on the system performance data ga

This report investigated the use of fluorine in the form of the difluoramino (NF2) group as an oxidizing moiety. Bis- and tris-difluoramino perfluorobutane, previously unknown, were especially synthesized for this study. Detonation calorimetry was performed to determine the exact detonation product composition and the hast of detonation of a series of NF2 compounds and mixtures. Cylinder tests were then performed to determine their detonation performance. Similar tests on NO2 compounds were used for comparison. For reasons of toxicity and safety, remote mixing and loading apparati were designed and built for certain of the materials. Materials were chosen to highlight certain of the detonation products. Hydrogen fluoride was found to be a favorable detonation product compared with H2O, CO2 outperforms CF4 at all cylinder expansion ratios, and Al2O3 was a favorable detonation product compared to AlF3. The most important result is the better understanding of the mechanism of reaction of small-part [abstract truncated]
