摘要:
选择乐安河-鄱阳湖段等典型湿地为研究区,在乐安河流域共设置16个典型样点,于2012年采集水样、底泥沉积物等样品,进行Cu、Pb、Cd等重金属污染的监测与评价,并对水体中pH值、总氮、总磷、COD等水质指标进行监测分析,探讨水体pH值、总氮、总磷、COD等水质指标对重金属Cu、Pb、Cd等污染物在水体及底泥沉积物中的迁移转化影响。结果表明:水环境因子中的总氮含量、总磷含量与水体中的Pb含量呈显著负相关;而水体总氮含量与水中的Cd含量呈显著正相关,且与土壤中的Cd含量呈显著负相关;水体COD含量与水样中的Cu含量呈显著正相关,水体pH值和水体中的Cu含量和水样中的Pb含量呈显著负相关。
Abstract:
The typical wetland of Le’an River and Poyang Lake is selected as the research area,and 16 typical sam-pling sites in the Watershed of Le’an River are set up. Sediment samples and water samples are collected from dif-ferent sampling sites in 2012,and detected the contents of Copper,Lead,Cadmium and other heavy metals pollutants of the all samples in order to evaluate the heavy metals pollution. Some water environmental factors of the water sam-ples are also detected such as pH value,total nitrogen,total phosphorus,chemical oxygen demand( COD)and so on, in order to study the effects and impacts of the above water environmental factors on the migration and transforma-tion of the above heavy metals from water to sediment. The results indicated that the contents of Lead in the water samples showed significant negative correlation with the contents of total nitrogen and total phosphorus of the water samples,and the contents of Cadmium in the water samples showed significant positive correlation with the contents of the total nitrogen in water samples,and the contents of Cadmium in the sediments samples showed significant neg-ative correlation with the contents of the total nitrogen in water samples. The contents of chemical oxygen demand in the water samples showed significant positive correlation with the contents of Copper in the water samples,and the pH values of the water samples showed significant negative correlation with the contents of Copper and Lead in water samples.
