“High use of pesticides has been correlated with both exposure and acute pesticide-related illness, and there is evidence for an association with chronic disease outcomes. Some research indicates that proximity to agricultural fields is correlated with measured concentrations in homes (Bradman et al., 2007; Harnly et al., 2009). A study in California comparing farmworker homes to homes of low-income urban residents found indoor concentrations of an agricultural pesticide only in homes of farmworkers (Quiros-Alcala et al., 2011). Another study, based on data from the California Pesticide Use Report (PUR) database, found that nearby agricultural pesticide use was significantly associated with pesticide concentrations in carpet dust (Gunier et al., 2011)…Because of their physical and chemical characteristics, fumigants and other volatile pesticides are most likely to be involved in pesticide drift incidents and illnesses. However, any pesticide that is applied by air or sprayed during windy conditions can drift over neighboring communities (Coronado et al., 2011; Lee et al., 2011).”
