In a study begun in 1999, the Environmental Protection Agency (EPA) investigated the temporal and spatial distributions of pesticides applied by homeowners and commercial applicators for indoor crack and crevice and exterior perimeter treatments. In each participating household, pesticide levels in indoor air at 10-cm and 75-cm above the floor (child's breathing zone) were measured pre- and post-application (0-14 days), along with dermal- and vacuum-dislodgeable floor residues, deposition on table tops and dinnerware, absorption by surrogate food, and residues on children's hands and toys. Surface soil residues were measured in the case of perimeter application. Monitoring devices and methods used include the URG 2500 air samplers (PM 2.5 inlet), the HVS3 vacuum sampler, the PUF Roller, hand wipes, and various techniques for deposition monitoring. Results from the study demonstrate the nature and magnitude of translocation of pesticides from the areas of application to surfaces accessible for human contact. This paper presents data from two indoor applications of diazinon and one outdoor (perimeter) application of chloropyrifos. The post-application redistribution of the pesticides within the home and the exposure potentials via various routes (respiration, dermal contact, ingestion) are discussed.
