背景：在流行病学研究中，住宅与农业农药施用场所的接近程度已被用作暴露的替代指标，尽管人们对住宅中农药水平与农药的关系知之甚少。目的：确定粉尘中农药浓度的决定因素。方法：我们收集了地毯灰尘样本，并绘制了加利福尼亚州89个住宅1250米范围内的农作物分布图。我们测量了农业中广泛使用的七种农药的浓度（西威因、毒死蜱、氯二甲基、二嗪农、异丙酮、磷和辛）。我们仅从一个全州范围的数据库中，并通过将数据库与作物地图联系起来，估计了住宅附近农业农药的使用情况。我们计算了收集灰尘前180天、365天和730天内距离住所500米和1250米范围内的农药使用密度，并评估了农业农药使用估计值与地毯粉尘中农药浓度之间的关系。结果：在7种农药中，有5种农药在过去365天内1250 m范围内使用过农药的居民的农药浓度显著高于附近未使用农药的居民。与农药浓度相关性最高的通常是在住所1250米内和采集样本前730天的使用情况。也考虑到职业和家庭使用农药的回归模型只能解释农药浓度的少量变化（4-28%）。结论：住宅附近的农业农药使用是地毯粉尘中农药浓度的重要决定因素。
Background: Residential proximity to agricultural pesticide applications has been used as a surrogate for exposure in epidemiologic studies, although little is known about the relationship with levels of pesticides in homes. Objective: We identified determinants of concentrations of agricultural pesticides in dust. Methods: We collected samples of carpet dust and mapped crops within 1,250 m of 89 residences in California. We measured concentrations of seven pesticides used extensively in agriculture (carbaryl, chlorpyrifos, chlorthal-dimethyl, diazinon, iprodione, phosmet, and simazine). We estimated use of agricultural pesticides near residences from a statewide database alone and by linking the database with crop maps. We calculated the density of pesticide use within 500 and 1,250 m of residences for 180, 365, and 730 days before collection of dust and evaluated relationships between agricultural pesticide use estimates and pesticide concentrations in carpet dust. Results: For five of the seven pesticides evaluated, residences with use of agricultural pesticides within 1,250 m during the previous 365 days had significantly higher concentrations of pesticides than did residences with no nearby use. The highest correlation with concentrations of pesticides was generally for use reported within 1,250 m of the residence and 730 days before sample collection. Regression models that also accounted for occupational and home use of pesticides explained only a modest amount of the variability in pesticide concentrations (4–28%). Conclusions: Agricultural pesticide use near residences was a significant determinant of concentrations of pesticides in carpet dust for five of seven pesticides evaluated.
