As part of a project designed to develop a framework for extrapolating acute central nervous system (CNS) effects of hydrocarbon solvents in animals to humans, experimental studies were conducted in rats and human volunteers in which acute CNS effects were measured and toxicokinetic data were collected. A complex hydrocarbon solvent, white...

An analytical method for the assessment of the exposure of workers to the pesticide propoxur through biological monitoring has been developed. This study was part of a survey of occupational exposure to pesticides used in greenhouses for the growing of ornamental plants. In order to assess the actual absorbed amount of propoxur in the body, an...

An HPLC method was developed for estimation of dermal exposure of greenhouse workers to the pesticide bupirimate. Chromatography was performed on a cyano-modified silica column with methanol-water (6:4 by volume) containing 5 g/L ammonium sulfate as eluent. UV detection at 310 nm was used for quantitation. Dermal exposure was assessed by letting...

Health hazard surveys have been conducted on Dutch bulb farms and in greenhouses used for cultivation of carnations in order to determine occupational exposure to the fungicides zineb and maneb. Occupational exposure is estimated by determining inhalatory and dermal exposure. Inhalatory exposure is measured by personal air sampling and dermal...

As part of a survey of occupational exposure to pesticides in greenhouses for growing ornamentals, analytical methods were developed and validated for the measurement of exposure of workers to the pesticide abamectin. Abamectin consists of a mixture of avermectin-B1a and avermectin-B1b, which are members of a class of fermentation products of...

Measurement of occupational exposure to styrene in industry showed that concentrations measured with the diffusive sampler 3M-3500 Organic Vapor Monitor were about 30 percent lower than those obtained with SKC Jumbo charcoal tubes. Samples were taken simultaneously: 99 paired personal samples and 66 paired stationary samples. The results showed...
