Description:
Yuma County is responsible for growing much of the nation's fresh fruit and vegetable supply during the winter months. These crops are tended by seasonal and migrant laborers who frequently live near the edge of the fields with their families. Many of these pesticides are pyrethroids, some are dinitroanilines. Further, diazinon and chlorprifos are used in many of these substandard dwellings to combat termites and roaches. As a result, children living in these homes are at great risk for routine exposure to pyrethroids and cholinesterase inhibitors.This project will study 300 children recruited from the Valley Health Clinic a primary care provider that serves primarily low income Hispanic and Cocopah. A pesticide use questionnaire will be administered in the clinic and 100 families will be selected for multi-media sampling for pyrethroids and Ops in their homes. All 300 children will be evaluated for Cholinesterase inhibitors. It is expected that households of the upper 50% will be sampled. Air, dust, surfaces, and the children's hands will be sampled. Separate funding will be sought to evaluate other media. To model "total" exposure, these databases will be supplemented by regional information garnered while sampling for the NHEXAS project.
It is expected that the research will find that children from low SES households have greater exposure than those of the rest of the states as determined by the NHEXAS evaluation. Further, since more pesticides are used in the Yuma area, we expect to find greater pesticide exposure in Yuma than elsewhere along the US-Mexico Border.
