• Description:
  Twenty-five farm and 25 non-farm households in Iowa were investigated for agricultural pesticide contamination. Air, wipe, and dust samples were collected inside homes and primary family vehicles on two occasions during the spring and summer, 2001. Samples were analyzed for atrazine, metolachlor, acetochlor, alachlor, chlorpyrifos, glyphosate, and 2,4-D. Chlorpyrifos was detected most frequently in house wipe samples, followed by acetochlor, metolachlor, and atrazine. Alachlor, glyphosate, and 2,4-D were not detected inside any homes; atrazine was not detected in any farm homes; and acetochlor and metolachlor were not detected in any non-farm homes. The maximum residue found in farm homes was 25 ng/cm2 for chlorpyrifos, 2 ng/cm2 for acetochlor, and 9 ng/cm2 for metolachlor. In non-farm homes, the maximum chlorpyrifos concentration was 4 ng/cm2, and only one sample was positive for atrazine (161 ng/cm2). Similar results were found inside the vehicles: chlorpyrifos was detected most often, followed by acetochlor, metolachlor, atrazine, and alachlor. Glyphosate and 2,4-D were not detected on the vehicle wipe samples. One hundred and eighty-five of 197 air samples (94%) were non-detectable for any pesticides. Pesticides were detected more often in the dust samples, especially in the farm homes. Chlorpyrifos, glyphosate, and 2,4-D were detected in all farm and non-farm homes. The geometric mean pesticide levels (ng/cm2) in farm and non-farm homes respectively were 0.13 and 0.02 for glyphosate, 0.19 and 0.05 for 2,4-D, 0.01 and 0.004 for chlorpyrifos, 0.004 and 0.003 for acetochlor, 0.02 and 0.002 for metolachlor, 0.01 and 0.001 for atrazine, and 0.002 and 0.001 for alachlor. Chlorpyrifos, 2,4-D, metolachlor, and atrazine were significantly different. These results indicate that pesticides can be detected in most homes, with farm homes being generally more contaminated. Dust samples appear to be a better measure for pesticides than wipe or air samples. [Description provided by NIOSH]
