粤北某市“土法炼砷”土壤中化学砷污染的研究

Research on Chemical Pollution Arsenic of Soil with Indigenous Method in North Guangdong

粤北某市“土法炼砷”造成的砷污染,严重破坏了当地生态环境,而且砷还会进入河流或地下水,严重威胁了当地及北江下游的饮用水安全和生态安全。本文对“土法炼砷”遗址现场进行调查取样,并对砷污染的特点进行了分析。

The environment has been polluted heavily by arsenic metallurgy activity with indigenous method in north Guangdong. What＇s more, the arsenic pollutants will enter the rivers or ground water body with rain water, which will threaten the drinking water and the environment safety along the Beijiang river. The investigations of the pollution locate and the check of the soil samples have been done in this paper, the chemical value of arsenic in the soils also been analyzed.
