摘要

摘要本研究旨在研究塞尔维亚博尔市采冶盆地附近城镇PM10中As、Cd、Pb、Ni四种重金属元素的浓度和空间分布。使用人体接触模型评估了每种重金属的人体健康风险。结果表明,在博尔市的三个测量点,空气中重金属元素的浓度都不显著。所有测试金属的空间分布格局与矿区和城镇人口最密集地区(国内来源和交通)的位置以及风向一致。污染评价表明,空气中砷、镉、镍和铅主要来源于工业、供暖和交通等人为污染源。非癌症健康风险评估表明,摄入是所有金属的主要暴露途径,铅和砷是儿童和成人非癌症风险的主要因素。计算了儿童的HI值(HI = 2.34-4.15E-06),表明儿童可能比成人面临更高的健康风险(HI = 2.67-4.73E-07)。所研究的所有重金属元素对塞尔维亚儿童和成人的非癌症风险以及As、Cd和Ni对儿童和成人的癌症风险均在可接受范围内。

Contamination and health risk assessment of heavy metals in PM10 in mining and smelting basin Bor in Serbia
Abstract The objective of this study was to investigate concentration and spatial distribution of four heavy metal elements (As, Cd, Pb, and Ni) in PM10 in town near mining and smelting basin, Bor (Serbia). Human health risks for each heavy metal were assessed using a human exposure model. Results showed that air does not contain significant heavy metal elements concentrations at all three measurement points in Bor. The spatial distribution pattern of all tested metals coincided with the locations of mining area and the most populated part of town (domestic sources and traffic), as well as wind direction. The contamination evaluation indicated that As, Cd, Ni and Pb in air originated from anthropogenic sources-industry, heating and traffic. The non-cancer health risk assessment showed that ingestion was the primary exposure route for all metals and that Pb, and As were the main contributors to non-cancer risks in both children and adults. HI values were calculated for children (HI = 2.34–4.15E-06), indicating that children will likely experience higher health risks compared with adults (HI = 2.67–4.73E-07). The non-cancer risks posed by all studied heavy metal elements and the cancer risks posed by As, Cd, and Ni to both children and adults in Serbia fell within the acceptable range.
