农业农药在农业工人和农业社区居民家中的沉积是一个主要的环境卫生问题。家庭清洁活动在清除家庭表面杀虫剂方面的有效性尚未经过测试。进行了一项干预研究，以评估在10个农场工人家庭中清洁窗台、地板和地毯的有效性。获得有机磷（OP）农药残留基线测量值，采用标准化清洁干预，并在清洁后24-48小时和12个月后进行农药残留随访测量。对室内粉尘中6种有机磷农药进行了分析。所有家庭的地板和窗台上都有可检测到的OP农药基线水平。油毡地板的清洁对农药残留量的去除效果不明显，不同农药的清洁效果不同。窗台上总OP农药清除效果显著（中位数减少0.0029微克/厘米(2)，单侧p值= 0.01）。蒸汽清洗地毯基本上可以将含量降低到无法检测的水平。在12个月内，地毯中的含量已累积到基线水平的三分之一。这些结果提供了证据，证明清洁做法可以减少农业家庭中的农药用量；然而，被清洁的表面类型和家中存在的杀虫剂可能会影响结果。
The deposition of agricultural pesticides in the homes of agricultural workers and residents of agricultural communities is a major environmental health concern. The effectiveness of home cleaning activities in removing pesticides from home surfaces has not been tested. An intervention study was conducted to assess the effectiveness of cleaning windowsills, floors and carpets in a sample of 10 farmworker homes. Baseline measures of organophosphorus (OP) pesticide residues were obtained, a standardized cleaning intervention was applied and follow-up measures of pesticide residues were obtained within 24-48 hours after the cleaning and 12 months later. House dust was analyzed for six OP pesticides. All homes had detectable baseline levels of OP pesticides on floors and windowsills. Cleaning of linoleum floors was ineffective in removing total pesticide residues and cleaning effectiveness varied among the pesticides. The cleaning of total OP pesticides on the windowsills was effective (median decrease was 0.0029 microg/cm(2), 1-sided p-value = 0.01). Steam cleaning carpets essentially reduced the amounts to non-detectable levels. In 12 months the levels in carpets had accumulated to one-third of the baseline levels. These results provide evidence that cleaning practices can reduce the amount of pesticides in agricultural homes; however the type of surface being cleaned and the pesticides present in the home may influence results.
