Biomonitoring of Persons Exposed to Insecticides Used in Residences

摘要

Pesticides used indoors inevitably result in some unitentional and unavoidable exposures of residents. Measured dosages of residents are well below toxic levels. Exposures (μg/kg-day) are substantially less and occur over a longer time than suggested by unvalidated estimates derived form previous extreme, conservative default assumptions based solely on environ- mental residues. Human chlorpyrifos exposures were monitored following three different types of applications: fogger, broadcast, and crack-and-crevice.
