Pesticides, polynuclear aromatic hydrocarbons (PAHs), lead (Pb), and other metals accumulate in home soil and house dust. Exposure of infants and toddlers to Pb by dust may be greater than other pathways. Many pollutants found in carpet dust are protected from degradation and accumulate over time. Greater numbers of pesticides are found in house dust than in indoor air. Pb and PAH concentrations appear to be magnified in house dust when compared with midyard and walkway soil samples. Studies using methods developed by the U.S. EPA show evidence of track-in and/or carry-in of Pb, PAHs and pesticides on clothes. Preliminary results of an eight-home study report PAHs inhouse dust at 1 to 100 ppm and suggest track-in as a major source of PAHs in house dust.
