• Description:
  Organophosphate pesticides (OPs) are related to ill health among adults, including farmworkers who are exposed to OPs as part of their regular work. Children of both farmworkers and non-farmworkers in agricultural communities may also be affected by pesticide exposure. Study groups of 100 farmworkers with a referent child (aged 2-6 years) and 100 non-farmworkers with a referent child were recruited to participate in three data collection periods over the course of a year. At each collection, participants provided three urine samples within 5 days, and homes and vehicles were vacuumed to collect pesticide residues in dust. In thinning and harvest seasons, farmworkers and their children had higher dimethyl urinary metabolites than non-farmworkers and their children. During the non-spray season, the urinary metabolites levels decreased among farmworkers to a level comparable to that of non-farmworkers. Farmworkers consistently had higher pesticide residues in their home and vehicle dust. Differences exist between farmworkers and non-farmworkers in urinary metabolites, and the differences extended throughout the agricultural seasons. OP metabolites are seen at much higher levels for farmworkers and their children than for non-farmworkers and their children during agricultural seasons when OPs are in use. These metabolite levels were significantly higher than the nationwide NHANES IV survey and up to 10-fold higher than other rural agricultural studies. [Description provided by NIOSH]
