黄河三门峡段沉积物中重金属含量的研究
|
摘要
在黄河三门峡段采集了表层沉积物样品,采用ICP-MS测定了沉积物中重金属元素铬、锰、镍、铜、砷、镉、铅、铜的含量。结果表明,各元素含量在0.05～900mg/kg,锰的含量最高,汞的含量最低。铬、铜、铅和汞的含量均满足国标规定的土壤环境质量二级标准,镍、砷和镉的含量满足三级标准。
Surface sediment samples were collected from the Sanmenxia section of the Yellow River.The contents of heavy metals such as chromium,manganese,nickel,copper,arsenic,cadmium,lead and copper in the sediments were determined by ICP-MS.The results showed that the content of each element was between 0.05 and 900 mg/kg,the content of manganese was the highest,and the content of mercury was the lowest.The contents of chromium,copper,lead and mercury all meet the secondary environmental standards for soil environmental quality specified by the national standard.The contents of nickel,arsenic and cadmium meet the thirdclass standard.
