以安徽省自然土壤背景值为参数，以国家土壤环境质量二级评价标准为依据，结合单污染指数和综合污染指数的计算，对铜陵市老洲乡蔬菜基地土壤重金属污染现状进行了评价。结果表明，土壤中5种重金属的平均含量均低于国家土壤重金属污染物二级标准，Hg、As和Cu的平均含量超过安徽省自然土壤背景值；但单项污染指标均未超过1．0，综合污染指数均在0．7以下，属于安全范围。
以安徽省自然土壤揹景值為參數，以國傢土壤環境質量二級評價標準為依據，結閤單汙染指數和綜閤汙染指數的計算，對銅陵市老洲鄉蔬菜基地土壤重金屬汙染現狀進行瞭評價。結果錶明，土壤中5種重金屬的平均含量均低于國傢土壤重金屬汙染物二級標準，Hg、As和Cu的平均含量超過安徽省自然土壤揹景值；但單項汙染指標均未超過1．0，綜閤汙染指數均在0．7以下，屬于安全範圍。

The research on the heavy mental content in the vegetable base of Laozhou Town, Tongling City, Anhui Province was introduced, by taking the background value of some heavy metal in natural soils of Anhui Province as references and the national environmental quality standard for soils as the basis. The results showed that, the average content of the five heavy metals in this area was lower than the national standards for Grade II. But the average contents of Hg, As and Cu exceeded the background value of some heavy mental in natural soils of Anhui Province. Each pollution index was lower than 1.0 and the comprehensive pollution index was below 0.7, which were in the limits of safety.
