The long-term goal of this research is to improve exposure assessment methods for epidemiological studies of agricultural pesticide use and cancer. The specific aims of this research proposal are: 1. To validate a set of geographic-based metrics for exposure assessment to agricultural pesticides using environmental samples of household dust. 2. To evaluate change in predicted land cover for use in a geographic-based exposure metric over a multi-year period. 3. To evaluate how seasonal calculation of a metric for exposure to agricultural chemical use effects potential household exposure. A procedure has been developed for predicting the likelihood that pesticides used in agricultural operations in the vicinity of a residence will be transported to inside the residence. This study is designed to use measurement of agricultural pesticides in household dust to test the validity of the procedure.

这项研究的长期目标是改善农药使用和癌症流行病学研究的暴露评估方法。 这项研究建议的具体目的是：1。验证一组基于地理的指标，以使用家庭灰尘样本对农业农药进行暴露评估。 2。评估在多年内在基于地理的敞口度量中使用的预测土地覆盖的变化。 3。评估暴露于农业化学使用的季节性计算如何影响家庭暴露。已经开发了一种程序来预测住所附近农业运营中使用的农药的可能性。 这项研究旨在使用家庭粉尘中农药的测量来测试该程序的有效性。
