The aim of this work was to evaluate contamination by polychlorinated biphenyls and mercury in soil, and to assess exposure level to both contaminants in children living in San Felipe, Nuevo Mercurio, Zacatecas, Mexico. We found soil levels of total polychlorinated biphenyls ranging from non detectable (nd) to 190 μg/kg. Mercury soil levels ranged from 8.9 to 10215.0 mg/kg. Exposure levels of total polychlorinated biphenyls assessed in blood and urinary mercury in children living in the studied community were 1,600 ± 8,800 ng/g lipid and 4.2 ± 7.1 μg/g creatinine, respectively.
本研究旨在评估墨西哥萨卡特卡斯州新梅库里奥圣菲利普儿童生活土壤中多氯联苯和汞的污染情况，并评估儿童对这两种污染物的暴露水平。我们发现土壤中的总多氯联苯含量范围从未检出（nd）到 190μg/kg。土壤中的汞含量范围为 8.9 至 10215.0mg/kg。研究社区中儿童血液和尿液中总多氯联苯及汞的暴露水平分别为 1600±8800ng/g 脂质和 4.2±7.1μg/g 肌酸酐。
