Although, the Yaqui and Mayo valleys are the most important agricultural areas in Sonora, there is only limited data of the pesticides residue in soils in these valleys. This study measured the organochlorine pesticides (OCPs) in 234 soil samples (residential and agricultural) from 24 communities. The global results (mean, range) indicated that benzene hexachloride (19.2, ND-938.5 μg g(-1)), endrin (6.6, ND-377.3 μg g(-1)) and DDTs (36.45, ND-679.7 μg g(-1)) were the dominant contaminants. Soil is one of the most important routes of exposure to OCPs in the population of southern Sonora and this study can be used to establish background levels of OCPs.
虽然亚基和梅奥山谷是索诺拉州最重要的农业区，但这些山谷土壤中农药残留的相关数据非常有限。本研究共采集了 24 个社区的 234 个土壤样本（居民区和农业区），测量了其中的有机氯农药（OCPs）。整体结果（平均值，范围）显示，六氯苯（19.2，未检出-938.5μg/g）、艾氏剂（6.6，未检出-377.3μg/g）和滴滴涕（36.45，未检出-679.7μg/g）为主要污染物。土壤是索诺拉州南部人群接触 OCPs 的最重要途径之一，本研究可用于建立 OCPs 的背景水平。
