摘要 在2008年4月~2009年3月对临钢降尘样品进行采集,利用AAS nov AA400原子吸收光谱仪对降尘中重金属元素全量以及溶于水和弱酸中的重金属含量进行了测定与分析.结果表明,各采样点降尘中的Pb含量平均是当地土壤环境背景值的9倍之多,最高达11倍以上,其次Zn、Cd、Mn含量也都超过全球平均含量及当地土壤环境背景值;本次所监测的重金属都能不同程度的溶于水和弱酸中,临汾市的降雨多呈弱酸性,临钢降尘中的重金属可能随着雨水进入土壤,从而对土壤等环境造成污染. From April 2008 to March 2009,dustfall generated by Linfen iron and steel works was collected.Using AAS nov AA 400 atomic absorption spectrometry,the total concentration of heavy metals in dustfall and dissolved concentration in water and weak acid was measured and analyzed.The results show that,the average concentration of Pb in dustfall was 9 times as that in the local soil background,the maximum concentration of Pb up to 11 times,subsequently the concentration of Zn,Cd and Mn were also in excess of that in the local soil environmental background and global average concentration.Because the concentration of heavy metals dissolved in weak acid was significantly greater than that in water,normal rain was state of weak acid in Linfen City,which makes heavy metals in dustfall generated by Linfen iron and steel works penetrate the soil with rain,and further contaminated to the soil and other environment.
