摘要
摘要:测定了摩洛哥埃特阿马尔(Oued Zem)地区土壤样品中金属的浓度。矿区表土样品中Cd、Cr、Cu、Fe、Pb和Zn的平均含量分别为:2.12、135、34.9、214、9.13和90.8 mg kg−1。还对金属摄入、皮肤吸收和土壤吸入造成的人类健康风险进行了评估。对于非致癌风险,儿童的统一危害指数(HI)值超过了铬(13.1)的安全水平(HI=1)。成人的HI值(1.74)也超过了铬的安全水平。儿童的铅和镉的HI值分别为0.69和0.68。铬的致癌风险超过了儿童(1.005 e -03)和成人(1.42E-04)的可容忍范围(1E-06至1e -04)。铅和镉导致的癌症风险在儿童和成人可接受的范围内。此外,在儿童和成人中,口服土壤颗粒比皮肤吸收或吸入对铬的致癌和非致癌风险都有更高的贡献。
Levels of Metals in Soils of Ait Ammar Iron Mine, Morocco: Human Health Risks
Abstract The concentrations of metals were determined in soil samples collected in Ait Ammar (Oued Zem, Morocco). The mean Cd, Cr, Cu, Fe, Pb and Zn contents in the mining topsoil samples were: 2.12, 135, 34.9, 214, 9.13 and 90.8 mg kg−1, respectively. Human health risks developed from metal ingestion, dermal absorption and inhalation of soils were also evaluated. For non-carcinogenic risks, united hazard index (HI) values for children surpassed the safe level (HI=1) for Cr (13.1). Values for HI in adults (1.74) also surpassed the safe level for Cr. The HI values for Pb and Cd for children were 0.69 and 0.68, respectively. Cancer risk due to Cr surpassed the tolerable range (1E-06 to1E-04) for children (1.05E-03) and for adults (1.42E-04). Cancer risks due to Pb and Cd were within acceptable ranges for both children and adults. Furthermore, oral ingestion of soil particles contributed more highly to both carcinogenic and non-carcinogenic risk from Cr than either dermal absorption or inhalation in both children and adults.
