    Assessing the Potential for Doormats to Reduce Pesticide Residues in the Home
    (2006-05-04) Ganser, Leanne Marie; Brown, Amy E; Marine-Estuarine-Environmental Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This study examined the recommended practice of using doormats at entryways into the home to reduce indirect pesticide exposure. Using doormats to reduce track-in of pesticides is commonly recommended to pesticide applicators, but no studies of the usefulness of this recommendation appear in the literature. The effectiveness of doormats was evaluated by determining the soil levels dislodged from doormats and by determining the ability for laundering to remove pesticide residues embedded into the mats. The performance of three doormat types was assessed. High levels of soil were dislodged from all doormat types. Results from laundering mats showed large variability in the level of residues detected. The results from both studies were influenced by the methods used to test the dislodgeability and effectiveness of laundering. The results of the study suggest further studies are needed to determine the effectiveness of doormats to reduce the potential for pesticide contamination inside the home.
