南充境内嘉陵江水生态系统中五种重金属的分布

Distribution of Five Heavy Metals in Aqucous Eco-System of the Jialing River in Nanchong City

利用火焰原子吸收分光光度法测定南充市境内嘉陵江流域水生态系统(河水、植被、河泥及鱼类)中的五种重金属(Cu、Pb、Cd、Ag、Zn)的含量,并分析了植被对重金属的吸收富集.本文对研究南充市境内嘉陵江流域环境状况及其水生态系统污染的进一步防治提供了科学依据.

We have used FAAS in measuring the content of five heavy metals in aqueous cdo-system of the Jialing River in the Nanchong City, including the river water, vegetation, river mud and fishes, and analyze the absorption and accumulation of heavy metals in Jialing River vegetation. This study provides scientific evidence for the study of the Jialing River environment and the prevention and cure for the pollution of aqueous eco-system of the Jialing River
