Abstract Methods have been developed to estimate children's residential exposures to pesticide residues and applied in a small field study of indoor exposures resulting from the intrusion of lawn-applied herbicide into the home. Transport of 2,4-D from the residential lawn into the home was measured following both homeowner and commercial application of this herbicide. Sampling methods included particle size-selective indoor air sampling; wipe sampling of floors, sills, tables; the polyurethane foam (PUF) roller for dislodgeable carpet surface residues; and the HVS3 vacuum sampler for floor dust. Personal exposure samples included hand wipes and morning void urine samples. Pesticide spray drift was found to result in only a relatively minor increase in indoor pesticide levels. Post-application air intrusion from closed house ventilation and the opening and closing of doors and windows increased indoor background levels 6-fold, while track-in by high activity children and pets, and wearing shoes indoors, increasing indoor levels by 37-fold. Indoor 2,4-D levels were found to increase continually over a one-week period, with the increase in indoor air levels corresponding to the increased floor dust levels, suggesting resuspension of house dust by human activity. Similar estimates of non-dietary exposure are obtained from models based on 100 mg dust by human activity. Similar estimates of non-dietary exposure are obtained from models based on 100 mg dust ingestion and surface contact simulated by the PUF roller.
