Field Studies Monitoring Worker Exposure to Pesticides

Source

These studies were conducted to collect data on pesticide exposure levels acquired by applicators during typical spray operations. This information should complement toxicological data. Measurements from workers engaged in routine forestry operations were made for crews spraying two phenoxy herbicides, 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) and 2,4-dichlorophenoxyacetic acid (2,4-D). In less extensive studies, exposures to mixers and applicators of o-ethyl-o-4-nitrophenyl phenylphosphonothioate (EPN) in cotton fields and paraquat in grape vineyards were evaluated. Levels of the pesticides were measured in the breathing zone of workers, on patches attached to workers' clothing, and from urine excreted during and after spray operations. These methods of evaluation showed that workers in these spray operations received some exposure to these pesticides, but levels of exposure in all tests were well below any amounts shown to be toxic to laboratory animals in toxicological studies
