  • 摘要: 采用美国最新法定重金属污染评价方法TCLP法(Toxicity characteristic leaching procedure)对湖南省资江流域土壤重金属生态风险进行评价.结果表明,资江流域土壤As、Cd、Cu、Zn、Ni和Pb的有效态含量分别在0.07-9.85、0.10-1.49、0.09-3.58、0.94-90.55、0.13-2.50 和0.18-8.25 mg·kg-1范围之间,TCLP提取的土壤As、Cu、Zn、Ni、Pb有效态量分别与其总量之间存在显著的相关关系.采用内梅罗综合污染指数进行评价,发现资江流域43个土壤样品中属安全水平、轻污染水平和中污染水平的比率分别为90.7%、7.0%和2.3%.
    Abstract: The ecological risk of heavy metals in soils from Zijiang River reaches, Hunan Province, China, was evaluated by toxicity characteristic leaching procedure (TCLP). The results showed that the levels of available As, Cd, Cu, Zn, Ni and Pb in soils were 0.07-9.85 mg·kg-1, 0.10-1.49 mg·kg-1, 0.09-3.58 mg·kg-1, 0.94-90.55 mg·kg-1, 0.13-2.50 mg·kg-1 and 0.18-8.25 mg·kg-1, respectively. The contents of available As, Cu, Zn, Ni and Pb in soils were significantly correlated with their total contents in soils. Based on Nemerow pollution index, the soil samples in the categories of safety level, light pollution level and medium pollution level accounted for 90.7%, 7.0% and 2.3% of the total soil samples, respectively. TCLP is an effective method for ecological risk assessment for soil heavy metals.
