Environmental survey and medical investigation of workers in relation to exposure to airborne dust containing seed treating chemicals as pesticides. Exposures to thiram, captan (133062), aldrin (309002), Victoria green (569642), gamma-benzenehexachloride (58899), and beta-benzenehexachloride (319857) are determined as not excessive. Mercury (7439976) is not detected in blood samples as indicator of exposure to Panogen 15 and Cerasan M organomercury compounds; red blood cell cholinesterase levels are normal, as indicator of malathion (121755) poisoning. Recommendations are made for improvement of design and maintenance of exhaust ventilation equipment, fungicide handling and seed treating operations, housekeeping, use of protective clothing and approved respirators, personal sanitation, and noise exposure reduction and noise abatement.
