Abstract
The paper gives results of experiments to explore the relationships between the insecticide chlorpyrifos and its distribution into carpet, carpet dust, and reemission into air. Two total release aerosols containing 0.5% chlorpyrifos were applied in the living room and den of EPA's test house in North Carolina. Afterwards, surface and carpet depositions, and carpet dust concentrations were determined. Portions of the contaminated carpet were removed and placed in environmental chambers (0.53 cu m). Emissions of chlorpyrifos from carpet to air were determined. Air exchange rates and airborne chlorpyrifos concentrations were measured in the test house over a 2 week-period. Airborne chlorpyrifos concentrations in the treated rooms of the test house exceeded 10 micrograms/cu m of air following 1 hour of enhanced ventilation and declined by < 1 microgram/cu m by post-application day 14.
