室内农药暴露是一个日益令人担忧的问题，特别是对拟除虫菊酯这一常用农药类别。在移民农场工人家庭中，拟除虫菊酯浓度可能特别高，这些家庭经常住在离农田很近的地方，面临着恶劣的住房条件，可能会导致虫害和杀虫剂的高使用率。我们对居住在加利福尼亚州门多塔的母亲和孩子进行了一项基于人口的墨西哥移民加州：农业安全和适应(Micasa)研究，调查了农场工人家庭房屋灰尘中的拟除虫菊酯水平。本文介绍了2009年室内粉尘的农药使用数据和室内粉尘中拟除虫菊酯类农药的含量，通过问卷调查和GC/MS分析了55户家庭的单一粉尘样品中的顺式和反式氯氰菊酯、溴氰菊酯、氰氰菊酯和氯氰菊酯。顺式和反式氯氰菊酯的检出频率最高，为67%，中位浓度分别为244和172 ng/g粉尘。在52%的家庭中检测到氯氰菊酯，其中位浓度为186 ng/g粉尘。不到一半的样品中检出了氰氰菊酯、氯氰菊酯和溴氰菊酯。我们将我们研究中发现的拟除虫菊酯浓度与其他研究进行了比较，这些研究都着眼于农村和城市的家庭和托儿所。与这些研究相比，我们的研究中观察到顺式和反式氯氰菊酯和氯氰菊酯的检测频率和/或中位浓度较低。然而，在本研究的屋尘中，溴氰菊酯、氰戊菊酯和氯氰菊酯的检出率高于其他研究。因为在这项研究中，儿童尿中拟除虫菊酯代谢产物水平较高的家庭更有可能被分析，因此我们对家庭拟除虫菊酯水平的估计可能会出现积极的偏差。报告的室外杀虫剂使用量和室内粉尘中的氯氰菊酯水平呈正相关(rs0.28，p=0.0450)。此外，室内粉尘中的拟除虫菊酯总水平与现场工作人员进行的杀虫剂清点结果也存在正相关关系(rs0.32，p=0.018)，这可能是农场工人家庭中农药暴露的一个有用的预测指标。有必要进行进一步的研究，以充分调查这一措施的效用。
Indoor pesticide exposure is a growing concern, particularly for pyrethroids, a commonly used class of pesticides. Pyrethroid concentrations may be especially high in homes of immigrant farm worker families, who often live in close proximity to agricultural fields and are faced with poor housing conditions, potentially causing high pest infestation and pesticide use. We investigate levels of pyrethroids in the house dust of farm worker family homes in a study of mothers and children living in Mendota, CA, within the population-based Mexican Immigration to California: Agricultural Safety and Acculturation (MICASA) Study. We present pesticide use data and levels of pyrethroid pesticides in indoor dust collected in 2009 as measured by questionnaires and a GC/MS analysis of the pyrethroids cis- and trans-permethrin, cypermethrin, deltamethrin, esfenvalerate and resmethrin in single dust samples collected from 55 households. Cis- and trans-permethrin had the highest detection frequencies at 67%, with median concentrations of 244 and 172 ng/g dust, respectively. Cypermethrin was detected in 52% of the homes and had a median concentration of 186 ng/g dust. Esfenvalerate, resmethrin and deltamethrin were detected in less than half the samples. We compared the pyrethroid concentrations found in our study to other studies looking at both rural and urban homes and daycares. Lower detection frequencies and/or lower median concentrations of cis- and trans-permethrin and cypermethrin were observed in our study as compared to those studies. However, deltamethrin, esfenvalerate and resmethrin were detected more frequently in the house dust from our study than in the other studies. Because households whose children had higher urinary pyrethroid metabolite levels were more likely to be analyzed in this study, a positive bias in our estimates of household pyrethroid levels may be expected. A positive association was observed with reported outdoor pesticide use and cypermethrin levels found in the indoor dust samples (rs = 0.28, p = 0.0450). There was also a positive association seen with summed pyrethroid levels in house dust and the results of a pesticide inventory conducted by field staff (rs = 0.32, p = 0.018), a potentially useful predictor of pesticide exposure in farm worker family homes. Further research is warranted to fully investigate the utility of such a measure.
