阜新市农田土壤重金属污染分析

针对阜新采矿活动及畜禽养殖业产生的畜禽粪便对农田重金属的污染,造成严重的生态破坏和环境问题.采用土壤样品采集采用随机布点法,采集的土壤样品预处理后进行土壤重金属含量测定.测定结果表明:6种重金属A5、Cd、Cu、Ni、Pb、Zn含量均严重偏高,存在一定的重金属污染风险,尤其应重视Cd的污染风险.采矿活动是农田重金属的重要来源,同时畜禽养殖业所产生的畜禽粪便可能对土壤中的Cu、zn、As的增加有一定作用,当地农牧业生产和布局应适当考虑它们的土壤污染风险.

Analysis of heavy metal pollution on farmland in Fuxin

Mining activities and livestock manure result in heavy pollution on agricultural land and serious ecological and environmental impact in Fuxin. A study is conducted to measure the contents of heavy metals in soils. The soil samples are collected using random sampling. The results show that the level of six heavy metals, namely As, Cd, Cu, Ni, Pb, Zn, in soil samples are very high, which indicates that there is a risk of heavy metal contamination. Among those different metals, the risk of Cd pollution requir...
