摘要
对福建沿海地区4种不同用地类型的8种重金属元素进行了检测和评价,结果表明:水田污染最严重是Pb,菜园地是Hg,果园是As,旱地是As。在多项综合指数评价中,菜园土污染最严重,综合污染指数(P)达到1.18,其余依次为水田0.64,果园0.59,旱地0.47。在单项污染综合指数中,Hg和Cd污染最严重,其污染指数(I)分别达到0.86和0.61,其余依次为Cr、Pb、Cu、As、Zn、Ni。评价结果为进一步的土壤污染与治理提供了科学依据。
With inspection and evaluation about 8 soil heavy metal elements according to various land utilization in coastal area of Fujian province, the result showed that the serious pollution of soil heavy metal in paddy field is Pb, in vegetable land is Hg, in orchard and in dry land is As. Refer to integrated index of factors, the index of vegetable land is 1.18, which was polluted most obviously, the others was paddy field 0.64, orchard 0.59 and dry land 0.47 in turn. To index of single factor, Hg and Cd were 0.86 and 0.61 respectively, then is Cr、Pb、Cu、As、Zn、Ni in turn. The result will be regarded as scientific evidence for controlling and proceeding soil pollutant.
