Assessing safety of agricultural chemicals.
The objective of occupational health and safety programs in the chemical industry is to protect human health and the environment. Through studies in laboratory animals, bacteria, insects, and cultured cells, toxicologists collect data which allow them to predict which chemicals are likely to be hazardous to humans. The effects of acute (single high level exposures), subchronic (up to 6 months duration to sublethal levels), and chronic (lifetime to low level) exposures are studied. Toxicity involving all organ systems is evaluated. Specific end points such as skin sensitization, birth defects, mutations, accumulation in tissues, carcinogenesis, and other toxic effects are evaluated. The data collected are used to provide information for forming guidelines regarding the safe manufacture, handling, use, and disposal of agricultural and other chemicals. The results of toxicology studies are also used to support the registration of products with government agencies in Canada and other countries.
