摘要
"十二五"期间自治区加大了对伊犁河谷境内典型生态环境区域集中式饮用水源地土壤、农田、果园、菜地以及昭苏、特克斯和新源三大天然草场土壤汞(Hg)、镉(Cd)、铅(Pb)、砷(As)、铜(Cu)、铬(Cr)、镍(Ni)、锌(Zn)八种重金属元素的监测,通过对上述监测数据的统计分析和评价表明:伊犁河谷典型区域土壤重金属含量均低于《土壤环境质量标准》(GB 15618-1995)(二级、旱地)限值,整体处于清洁安全水平,尚未受到人为显著影响。
During the＂twelfth five- year＂plan,Xinjiang Autonomous Region increased monitoring in the typical ecological environment of Ili River Valley Area from drinking water source of soil,farmland,orchard,vegetable,and eight heavy metals in soil in three natural pasture soils of Zhaosu,Turks and Xinyuan,including mercury（ Hg）,cadmium（ Cd）,lead（ Pb）,arsenic（ As）,copper（ Cu） and chromium（ Cr）,nickel（ Ni）,zinc（ zinc）. The statistical analysis of the monitoring data and evaluation show that the Ili river valley area typical soil heavy metal content is below the soil environment quality standard GB15618- 1995（ secondary,dryland） limit,As a whole in a clean and safe levels,it has not been affected by artificial significantly.
