Abstract
In response to a confidential employee request, an evaluation was made of possible hazardous working conditions at Plant 4 of the Green Circle Growers (SIC-0181), Oberlin, Ohio. The company produces a variety of floriculture and nursery products in greenhouses. There were 57 workers in Plant 4. Area air sampling revealed residual diazinon (333415) concentrations in greenhouse sections with passive ventilation systems. Sampling for potential skin exposure showed diazinon in measurable quantities on the glove monitors of greenhouse laborers who handled plants treated with this insecticide 48 days earlier. Of six medically monitored employees, two had evidence of greater than 30% decreases in pseudocholinesterase (P-ChE) activity and one had a decrease in P- ChE activity approaching 30% indicating possible overexposure to organophosphate or carbamate pesticides. The authors conclude that inhalation exposures to residual pesticides after high volume spraying and cold fogging applications, and skin exposures to treated plants represented a health risk. The authors recommend that spraying applications be restricted to Friday evenings, and fogging operations be suspended until after the installation of mechanical exhaust ventilation systems was completed. Laborers should wear protective gloves when handling treated plants. A modified medical monitoring program should be extended to all employees potentially exposed to pesticides.
