| 中文摘要: |
| 为了解冶炼厂周边地区室内积尘中重金属的污染特征，掌握室内积尘中重金属暴露的健康风险，对辽宁锦州铁合金厂周边6个村庄（A村、B村、C村、D村、E村、F村）及对照区2个村庄（G村、H村）室内积尘中7种重金属（Zn、Cd、As、Cr、Cu、Ni、Pb）的含量水平进行分析，采用地累积指数评价室内积尘中重金属的污染特征，利用健康风险评估模型评估成人和儿童通过室内积尘暴露重金属的潜在健康风险。结果表明：污染区6个村庄室内积尘中Zn、Cd、As、Cr、Cu、Ni、Pb的平均含量分别为980.23、7.98、17.48、164.65、118.87、39.82、154.06 mg·kg-1，显著高于对照区2个村庄室内积尘重金属平均含量；地累积指数评价结果表明污染区室内积尘中Cd的污染程度较强；主成分分析表明辽宁锦州污染区和对照区室内积尘中的重金属来源于铁合金厂冶炼活动、大气沉降、燃煤等；健康风险评估结果表明锦州铁合金厂周边居民通过室内积尘暴露Cd、Cr、Ni和As的致癌风险均超出可接受风险水平。研究表明，锦州铁合金厂周边区域室内积尘中重金属污染及健康风险应予以重点关注。 |
| 英文摘要: |
| Pollution characteristics and health risk assessment were evaluated for heavy metals (Zn, Cd, As, Cr, Cu, Ni, and Pb) in household dust samples in regions of Jinzhou, Liaoning Province. Sixty-two household dust samples were collected from eight villages around the Jinzhou ferroalloy factory. Polluted areas included A, B, C, D, E, and F villages, while control areas included G and H villages. The results showed that the average concentrations of Zn, Cd, As, Cr, Cu, Ni, and Pb in household dust samples from polluted areas around the Jinzhou ferroalloy factory were 980.23, 7.98, 17.48, 164.65, 118.87, 39.82, and 154.06 mg·kg-1, respectively. The concentrations of heavy metals in household dusts of polluted area were significantly higher than those of control areas. Analysis of the geoaccumulation index indicated that Cd in household dust samples was at serious pollution levels. Principal component analyses indicated that the potential source of heavy metals in household dusts was industry activities of nonferrous metallurgy, atmospheric deposition, combusting coal, and so on. The potential cancer risk to adult and children exposed to heavy metals (Cd, Cr, Ni, and As) by household dust was above the accept risk level. Contamination of heavy metals in household dust and health risk assessment should be given attention. |
