Abstract
Breathing zone samples were analyzed for the pesticides 2,4-D (94757), Banvel (1918009), Buctril (1689845), and Roundup (38641940) at field stations of the Bureau of Reclamation (Bureau) (SIC-9511), US Department of the Interior at Fresno, Tracy, and Red Bluff, California and Bismarck, North Dakota in August, 1983 and June, 1984. The survey was requested by the Bureau to evaluate its pesticide application program. Work practices were observed during mixing, spraying, and cleanup operations. Pesticide concentrations in micrograms per cubic meter (microg/m3) were: 2,4-D, 1.8 to 2.6; Banvel, 1.2 to 1.4; Buctril, less than 2; and Roundup, less than 28. Only 2,4-D has a published standard, 10,000microg/m3 (OSHA). Observation of work practices indicated that Bureau employees had a good understanding of the hazards associated with pesticides. The authors note that the low concentrations of active ingredients (on the order of 0.5 to 3 percent) in the pesticide formulations contributed to the low airborne concentrations measured. They conclude that in the event of an accident or spraying under windy conditions, Bureau employees would have a slight increased risk of exposure. Recommendations include employee education, using protective clothing during mixing, and implementing programs of exposure recordkeeping.
