摘  要:
运用单因子污染指数、内梅罗指数及潜在生态风险指数对青海省高寒干旱区某金属冶炼厂周围土壤重金属污染状况进行了评价。结果表明,该区域土壤中的Zn、Cd含量都出现了不同程度的超标,少数样点Cd污染十分严重,土壤中的Cr、Cu、Pb、As未超标。在所采集的马铃薯、小麦、油菜样品中,有部分农产品Cd含量超出了国家规定的食品安全限制标准,存在一定的安全风险。

摘  要:
The pollution status of heavy metal elements in soil surrounding a smelting factory in Qinghai province was investigated and evaluated through single factor pollution index method,Nemerow pollution index method and potential ecological risk index method.The results showed that the content of heavy metal Zn and Cd in soil of that area exceeded the standard to different degrees;and at some spots Cd pollution was very serious.Content of heavy metal Cr,Cu,As and Pb was appropriate to the standard.In some of the crop samples such as potato,wheat,rape,concentration of Cd excessed the national required food security limits,had certain safety risk.
