湖南素以“有色金属之乡”著称。人类活动过程中产生的重金属废弃物,通过不同途径进入环境中,引发系列环境污染,例如水体重金属污染。重金属不同于有机物污染物,其在水体中具有相当高的稳定性及难降解性,同时具有生物富集效应,通过食物链直接或间接地影响人类的健康。本研究选取湘江长沙段8个位置的水样作为研究对象,对其常见重金属浓度进行空间分析,为湘江重金属分布及防护治理提供数据参考。 Hunan known as “non-ferrous metals town,” is known. Heavy metal wastes generated during human activities enter the environment through different channels and cause a series of environmental pollution, such as heavy metal pollution of water bodies. Heavy metals, unlike organic pollutants, have considerable stability and poor biodegradability in water and have bioaccumulation effects that directly or indirectly affect human health through the food chain. In this study, the water samples from 8 sites in Changsha section of Xiangjiang River were selected as the research object. The spatial distribution of their common heavy metal concentrations was analyzed to provide reference for the distribution of heavy metals in Xiangjiang River and its prevention and control.
