Assessment of Pollution and Enrichment of Heavy Metals of Cu,Pb,Zn on Aquatic Plants

A survey on the contents of heavy metals in soils and aquatic plants was conducted to determine and evaluate the contamination of heavy metals in this paper.The investigated areas were contaminated by heavy metals of Cu,Pb,Zn incoordinately,and the content of heavy metals of Cu,Pb,Zn in soils is related to the (human) activities,the main source of pollution of heavy metals.Different plants have different selective enrichment of heavy metals .The enrichment was correlated to the background of heavy metals in soils ,the more concentration of heavy metals in soils ,the more enrichment of heavy metals in aquatic plants.
