  title = {Pesticides in Dust from Homes in an Agricultural Area},
  abstract = {<p>We collected indoor dust samples from homes in the Salinas Valley of  California. Of 22 pesticides measured in 504 samples, permethrins and  the organophosphate chlorpyrifos were present in highest amounts. In  multivariate Tobit regression models among samples from 197 separate  residences, reported agricultural uses of chlorpyrifos, a herbicide  (2,3,5,6-tetrachloroterephthalate (DCPA)), and a fungicide (iprodione)  on agricultural fields were significantly (<em>p</em> &lt; 0.01)  associated, with 83%, 19%, and 49% increases, respectively, in dust  concentrations for each kg applied per day, near participant homes, in  the month or season prior to sample collection. However, agricultural  use of diazinon, which was 2.2 times that of chlorpyrifos, and of  permethrin were not significantly associated with dust levels. Other  variables independently associated with dust levels included temperature  and rainfall, farmworkers storing work shoes in the home, storing a  diazinon product in the home, housing density, having a home less clean,  and having an air conditioner. Permethrins, chlorpyrifos, DCPA, and  iprodione have either a log octanol−water partition coefficient (<em>K</em><sub>ow</sub>)  greater than 4.0, a very low vapor pressure, or both. Health risk  assessments for pesticides that have these properties may need to  include evaluation of exposures to house dust.</p>},
