冶炼厂烟气排放与土壤重金属污染

通过对某冶炼厂烟源对应的监测点土壤中铜、镉、铅1979年和1989—2004年监测数据的对比研究，证明了被测烟源1989年后对土壤中镉和铅无明显影响，对个别监测点1989—1997年铜的含量有明显的影响。1999年后，对铜的影响也基本消除。这说明1989年后，该厂加大了对烟源的治理力度，逐步消除了对监测区域土壤重金属的污染。经秩相关系数分析，排除烟源影响，部分被测点位土壤中铜和铅的上升趋势具有显著性意义。可以认为，还存在着新的污染因素。

Smelter Flue Gas Emissions and Pollution by Heavy Metals in Earth

Through the comparative study of the 1979 data and the 1989-2004 data of copper,cadmium and lead in the soil of the monitoring stations corresponding to the smoke source of a certain smeltery plant,the smoke source being monitored has been proved of having no obvious effect on cadmium and lead in the soil after 1989,and of having apparent effect on the content of copper in individual monitoring stations between 1989 and 1997.The effect on copper has been generally eliminated since 1999.This indicates the gr...
