摘要
测定了2005年、2011年和2021年某冶炼厂土壤中Hg的质量分数,并采用地累积指数法、潜在生态风险指数、非致癌风险评估法对冶炼厂附近土壤进行污染评价。结果表明:冶炼厂各采样点土壤中Hg的质量分数时空分布差异性较大,整体呈现出以冶炼厂为中心的扩散现象,距离冶炼厂最近的S4和S5采样点的Hg污染最为严重;冶炼厂附近的S2、S4、S5、S6、S7采样点Hg的污染,处于极重程度,具有极强的潜在生态风险;距离冶金厂最近的S4和S5采样点土壤中Hg的非致癌健康危害指数相对较高;儿童接触Hg的非致癌健康危害指数高于成人,对于Hg的暴露更为敏感。
The mass fraction of Hg in the soil of a certain smelter in 2005,2011,and 2021 was measured,and pollution assessment was conducted on the soil near the smelter using the ground accumulation index method,potential ecological risk index,and non carcinogenic risk assessment method.The results show that there is a significant difference in the spatiotemporal distribution of Hg mass fraction in the soil at each sampling point of the smelting plant,and the overall diffusion phenomenon is centered around the smelting plant.The closest S4 and S5 sampling points to the smelting plant have the most severe Hg pollution.The pollution of Hg at the S2,S4,S5,S6,and S7 sampling points near the smelting plant is at an extremely severe level and poses a strong potential ecological risk.The non carcinogenic health hazard index of Hg in the soil at the S4 and S5 sampling points closest to the metallurgical plant is relatively high.The non carcinogenic health hazard index of children exposed to Hg is higher than that of adults,making them more sensitive to exposure to Hg.
