摘要
多环芳烃(PAHs)和重金属(HMs)对环境和人类健康构成风险。确定优先控制污染物对于指导这些同步污染物的管理和控制非常重要。研究人员从中国西南部喀斯特高原城市贵阳的 64 个城市公园中采集了 247 份土壤样本,以确定多环芳烃和 HMs 的浓度、空间分布和健康风险。结果表明,二苯并(ah)蒽和苯并(a)芘是具有高生态风险的主要多环芳烃,而铬、锰和镍在 HMs 中具有较高的生态风险。多环芳烃有四个来源(生物质燃烧、焦炉、交通源和燃煤),而 HMs 有四个来源(交通源、燃煤、工业源和自然源)。经测定,多环芳烃的非致癌风险 (NCR) 和总致癌风险 (TCR) 均可忽略不计,处于可接受水平,比 HMs 低几个数量级。HMs 的 NCR 和 TCR 值相对较高,尤其是对儿童而言(11.9% 的 NCR > 1;79.1% 的 TCR > 10-4)。燃煤和天然来源对贵阳岩溶公园土壤中 HMs 的 NCR 和 TCR 值贡献最大。考虑到 HMs 的生物利用率,NCR 和 TCR 值相当低,这是因为 HMs 的残留量较高。对特定污染源的生态和人类健康风险的综合分析,为未来多环芳烃和HM同步污染的管理和控制指明了方向,尤其是在岩溶高原地区:在线版本包含补充材料,可查阅 10.1007/s12403-023-00534-3。
Integrated Insights into Source Apportionment and Source-Specific Health Risks of Potential Pollutants in Urban Park Soils on the Karst Plateau, SW China.
Polycyclic aromatic hydrocarbons (PAHs) and heavy metal(loid)s (HMs) pose risks to environmental and human health. Identification of priority control contaminants is important in guiding the management and control of these synchronous pollutants. A total of 247 soil samples were collected from 64 urban parks in the karst plateau city of Guiyang in SW China to determine the concentrations, spatial distributions, and health risks of PAHs and HMs. The results indicate that dibenz(ah)anthracene and benzo(a)pyrene are the main PAHs species of high ecological risk, and Cr, Mn, and Ni pose elevated ecological risk among the HMs. Four sources were identified for PAHs (biomass burning, coke oven, traffic sources, and coal burning) and HMs (traffic sources, coal burning, industrial sources, and natural sources). The non-carcinogenic risk (NCR) and total carcinogenic risk (TCR) of PAHs were all determined to be negligible and at acceptable levels, several orders of magnitude below those of HMs. The NCR and TCR values of HMs were relatively high, especially for children (11.9% of NCR > 1; 79.1% of TCR > 10-4). Coal burning and natural sources make the greatest contributions to the NCR and TCR values from karst park soils in Guiyang. Considering HMs bioavailability, NCR and TCR values were rather low, due to the high residual HM fractions. Integrated insights into source specific ecological and human health risk indicate future directions for management and control of synchronous PAH and HM pollution, particularly for karst plateau areas.
