摘要
对抚顺市城区4个典型区域的土壤重金属铜、锌、铅、镉、铬、镍、汞、砷的污染现状进行了调查和分析。结果表明:重金属含量在各典型区域内差异较大,说明点污染源有较大影响;固体废物填埋场及周边地区土壤污染等级为3级轻污染,重污染企业及周边地区和采矿区及周边地区土壤污染等级为2级警戒限,而污灌区及周边地区的土壤污染等级为1级安全;抚顺市城区4个典型区域土壤重金属潜在生态风险均处于低水平。
Heavy metals in soil included copper, zinc, lead, cadmium, chromium, nickel, mercury and arsenic in four typical areas of Fushun were investigated and analysed. The results showed that the concentration of heavy metals had large difference in 4 typical areas and point sources still had considerable influence. The soil pollution level around the dump was affected by light pollution, soil around heavily polluting industries was at warning level and wastewater irrigation district was at safety level. The potential ecological risk of soil in 4 typical areas was at low level.
