Personal and area air samples were analyzed at the Quechan Environmental Farm (SIC-0182) in Yuma, Arizona on January 25 and 26, 1980 to evaluate exposures to methomyl (16752775), malathion (121755), benomyl (17804352) and dexon (140567). The evaluation was requested by an authorized representative of the Quechan Tribe on behalf of approximately 40 workers. Only methomyl sampling was conducted during an entire work shift, since none of the other pesticides were used during the survey. Methomyl aerosol concentrations ranged from less than 0.87 to 7.94 milligrams per cubic meter (mg/CuM). One personal sample had a concentration of 9.55mg/CuM, which exceeded the threshold limit value of 2.5mg/CuM recommended by the American Conference of Governmental Industrial Hygienists. The authors conclude that a health hazard from exposure to methomyl does not exist because of the successful use of personal protective respirators and clothing. They recommend that a formal respirator program be instituted, respirator filters be changed frequently, workers be educated about pesticides and beverages containing salt be provided instead of salt tablets.
