Public health and environmental impacts of monosodium methanearsonate as used in bark beetle control in British Columbia by Frank N Dost( Book )

3 editions published in 1995 in English and held by 11 WorldCat member libraries worldwide

Monosodium methanearsonate (MSMA) is used in British Columbia to create lethal trap trees for control of bark beetle infestation. The average annual total area of treatment in the province is 650 hectares, dispersed over a wide range covering most of the interior where bark beetle infestations may occur. This report assesses the impacts of MSMA use, including its behavior and fate in the environment when used for forest insect control, the toxicology of MSMA and its toxicity to humans and to terrestrial and aquatic species, the routes by which MSMA may be ingested by humans, and the extent of exposure to MSMA from treated trees, including exposure to sawdust and smoke. The report concludes with an assessment of the MSMA health risk, including graded or consistent effects and the risk of systemic toxicity. A glossary and a MSMA material safety data sheet are included
Studies on environmental pollution by missile propellants by Frank N Dost( Book )

3 editions published between 1969 and 1970 in English and held by 8 WorldCat member libraries worldwide

The effects of NF3O on lower organisms have been surveyed. The gas causes minimum damage to plants when exposed for 30 minutes to concentrations as low as 5 ppm. Effects on goldfish maintained in aquaria under 1% NF3O for 30 minutes were negligible; salmon were moderately sensitive. Microorganisms in soil were only slightly decreased in numbers by one hour of exposure by continuously tumbling soil particles through 1% NF3O. Potentially useful decontamination reastions were studied. Interhalogens and N2F4 can probably be removed from the atmosphere by a mist of aqueous sodium bicarbonate solution. No reagent portable enough and sufficiently effective to remove OF2 and NF3O gas from the atmosphere was found. NF3 is virtually non-reactive
Toxicology and potential health risk of chemicals that may be encountered by workers using forest vegetation management options, part I : risk to workers associated with exposure to emissions from power saws by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

This report examines forest worker risks associated with exposure to exhaust emissions from power saws used in forest vegetation management. It first reviews previous research on emissions from two-stroke engines that provides information on the typical compounds found in those emissions and their human health effects. It then assesses the research investigating the degree of exposure to exhaust from power saws, primarily from measurements made during logging operations. Breathing zone concentrations of selected chain-saw exhaust components are estimated. The information on toxicity and exposure is then used to estimate non-cancer or systemic risks from carbon monoxide and aldehydes and cancer risks from such components of engine emissions as benzene and polycyclic aromatic hydrocarbons
Toxicology and potential health risk of chemicals that may be encountered by workers using forest vegetation management options, part III : risk to workers using 2,4-D formulations by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

2,4-D was first registered in 1947 as a broadleaf herbicide for use in all facets of vegetation management. Wide use of this herbicide has led to considerable research on the toxicology of 2,4-D formulations. This paper reviews research reported in the literature concerning the toxicology of 2,4-D and evaluates the risks to forest workers associated with exposure to 2,4-D formulations. It first summarizes the forms of 2,4-D used in commercial products and what is known about the behaviour of 2,4-D in the body (adsorption, metabolism, excretion). It then examines the herbicide's systemic toxicity (including human intoxication, general systemic effects, neurological effects, & effects on immune response), reproductive & developmental effects, mutagenic effects, and genetic toxicity & related cellular effects. The final section assesses the carcinogenic potential of 2,4-D, including discussion of the findings of several expert panels assembled to examine the experimental & epidemiological data. Selected epidemiological findings are also discussed specifically to illustrate the difficulties in deriving meaningful conclusions from these studies. Includes glossary
Pesticide testing for registration : toxicity, environmental behaviour and epidemiology by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

Pesticide registrants must present a broad array of required data to the government before the product can be registered. This paper discusses the types of toxicology & related testing that is necessary for registration. These requirements include toxicity data from acute, subacute, subchronic, & chronic studies using test organisms such as rabbits, rats, & mice; fate of the pesticide in the organism, including the metabolic conversions & derivatives, excretion, possible storage, and the rates at which these processes take place; impact of the product on wildlife, fish, & invertebrates; and the environmental residues of the pesticide (in plants, animals, drinking water, & soils) and bioaccumulation. The paper also discusses the role of epidemiological studies in the registration process and the evaluation of possible effects on humans
Toxicology and potential health risk of chemicals that may be encountered by workers using forest vegetation management options, part IV : risk to workers using glyphosate formulations by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

Glyphosate, as the isopropylamine (IPA) salt, is the active herbicide in formulations registered for forestry uses in Canada. This paper reviews research reported in the literature concerning the toxicology of glyphosate and evaluates the risks to forest workers associated with exposure to glyphosate formulations. It first summarizes what is known about the behaviour of glyphosate in the body (adsorption, metabolism, storage, excretion) and the general toxicology of glyphosate. It then examines the herbicide's dermal & eye toxicity, reproductive & developmental toxicity, genetic toxicity, and carcinogenic potential; the toxicology & behaviour of the surfactant used in the Vision[TM] formulation and the toxicology of that formulation; studies of forest worker exposure to glyphosate; and suicide attempts using glyphosate. The final section assesses risk to workers who apply Vision or who enter treated areas. Includes glossary
Principles of health effects evaluation and risk estimation for chemicals that may be encountered in forest vegetation management by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

This paper reviews the basic principles of health effects evaluation and risk estimation for chemicals, with reference to herbicides commonly used in Canadian forestry. It first presents some general concepts related to toxicology, environmental chemistry, and epidemiology, then explains the nature of interactions between chemicals and the body. The dose-response relationship for systemic effects (effects other than cancer) and for chemically induced cancer is also reviewed. The final section sets out general considerations related to risk assessment and specific considerations related to systemic, threshold-based effects and irreversible effects, whether or not threshold-dependent. Includes glossary

Toxicology and potential health risk of chemicals that may be encountered by workers using forest vegetation management options, part II : exposure to and absorption of herbicides used in forestry by Frank N Dost( Book )

3 editions published in 2003 in English and held by 6 WorldCat member libraries worldwide

This paper reviews a variety of research studies of worker exposure in forestry & agriculture, as well as some observations of homeowners & lawn care workers, in order to consider the exposure of forest workers to herbicides. It first summarizes general approaches to the assessment of worker exposure to herbicides, then discusses research on such matters as absorption of herbicides through skin contact, protective measures, urinary excretion of herbicide after exposure, variations in exposure when using different types of applicator equipment, contact with treated vegetation as a source of herbicide exposure, and exposure following burning of treated vegetation. The final section makes suggestions toward developing exposure standards for forest workers

Inorganic fluoride propellant oxidizers by D. J Reed( Book )

3 editions published in 1967 in English and held by 4 WorldCat member libraries worldwide

Certain inorganic fluorides were reviewed for their chemical, physical and toxicological properties. The compounds are nitrogen trifluoride; tetrafluorohydrazine; chlorine trifluoride; bromine pentafluoride; oxygen difluoride; hydrogen fluoride, and fluorine. Seeds and seedlings of bean, corn, pea, squash and sudan grass were exposed to air or water mixture of these compounds. Exposure of dry seeds to a gaseous 100% NF3 atmosphere for 1 to 8 hours caused inhibition of subsequent germination depending on the seed species. Exposure of seeds to a 10% N2F4 atmosphere for 1 hour completely inhibited germination of all five species of seeds. Exposure of dry seeds to less than 500 ppm of either bromine pentafluoride or chlorine trifluoride in air drastically reduced their subsequent germination even when the exposure time was for less than one hour. Exposures of plant seedlings to gaseous ClF3 in air at 500 and 2,000 ppm for 5 minutes resulted in extensive destruction of the plants; bromine pentafluoride-air mixtures were even more damaging than ClF3 atmospheres. Concentrations of N2F4 or NF3 up to 10,000 ppm in air were required to cause visible damage of plant seedlings after a 30 to 60 minute exposure period. Plant injury was caused by irrigation of plant seedlings with solutions formed by the reaction of ClF3 or BrF5 with water. The exposed seeds and seedlings were analyzed for fluoride content. The equipment and methods used for these exposures is described
Metabolism and pharmacology of inorganic and fluorine containing compounds( Book )

2 editions published in 1968 in English and held by 4 WorldCat member libraries worldwide

Studies have been made of the toxicology and chemistry of nitrogen trifluoride, tetrafluorohydrazine, chlorine trifluoride, bromine pentafluoride, and oxygen difluoride. Lethality of each agent by inhalation has been determined, as well as estimates of lethality after intraperitoneal administration. Experimental evidence suggests that the lethal effect of interhalogens is by corrosive local destruction of pulmonary surfaces, resulting in failure of gas exchange. Oxygen difluoride is thought to pass intact into the pulmonary cells where it reacts with biochemical reducing systems to ultimately cause cell death and structural failure. The nitrogen fluorides both cause intrinsically lethal levels of methemoglobin formation, but other pharmacologic activity by these compounds or their derivatives may also contribute to their toxic activity
Toxicology and potential health risk of chemicals that may be encountered by forest vegetation management workers, part VI : risk to workers using triclopyr formulations, Release[R] or Garlon[R] by Frank N Dost( Book )

2 editions published in 2003 in English and held by 4 WorldCat member libraries worldwide

Triclopyr (3,5,6-trichloro 2-pyridinyloxyacetic acid) is a herbicide active on broadleaf & woody plants. It is available as the butoxyethyl ester and the triethylamine salt. This paper reviews research reported in the literature concerning the toxicology of triclopyr and evaluates the risks to forest workers associated with exposure to triclopyr formulations. It first summarizes what is known about the behaviour of triclopyr in the body (adsorption, distribution, metabolism, excretion) and the acute & subacute toxicity of triclopyr. It then examines the herbicide's subchronic & chronic toxicity, reproductive effects, mutagenic effects, and carcinogenicity. The final section assesses the overall health risks to forest workers associated with the use of triclopyr ester. Includes glossary
