In this study, we assessed intracorporal mercury concentrations in subjects living on partially mercury-contaminated soils in a defined area in Switzerland. We assessed 64 mothers and 107 children who resided in a defined area for at least 3 months. Mercury in biological samples (urine and hair) was measured, a detailed questionnaire was administered for each individual, and individual mercury soil values were obtained. Human biomonitoring results were compared with health-related and reference values. Mothers and children in our study had geometric means (GMs) of 0.22 µg Hg/g creatinine in urine (95th percentile (P95) = 0.85 µg Hg/g) and 0.16 µg Hg/g (P95 = 0.56 µg Hg/g), respectively. In hair, mothers and children had GMs of 0.21 µg Hg/g (P95 = 0.94 µg/g) and 0.18 µg/g (P95 = 0.60 µg/g), respectively. We found no evidence for an association between mercury values in soil and those in human specimens nor for a health threat in residential mothers and children.
在这项研究中，我们评估了居住在瑞士一个特定地区部分受汞污染土壤上的受试者体内的汞浓度。我们评估了至少在该地区居住 3 个月的 64 名母亲和 107 名儿童。对生物样本（尿液和头发）中的汞进行了测量，为每个个体都进行了详细的问卷调查，并获得了个体的汞土壤值。将人体生物监测结果与与健康相关的参考值进行了比较。在我们的研究中，母亲和儿童的尿液中汞的几何平均值（GM）分别为 0.22μgHg/g 肌酐（第 95 个百分位数（P95）= 0.85μgHg/g）和 0.16μgHg/g（P95= 0.56μgHg/g）。头发中，母亲和儿童的 GM 分别为 0.21μgHg/g（P95= 0.94μg/g）和 0.18μg/g（P95= 0.60μg/g）。我们没有发现土壤中汞值与人体样本中汞值之间存在关联的证据，也没有发现居住在这些地区的母亲和儿童面临健康威胁的证据。
