Water Heavy Metal Potential Ecological Hazard and Loss of Liangtan River in Urban and Rural Connection Area in Chongqing

Abstract:

Exampled on the catchments area of LiangTan River in Chongqing, this paper analyzed the Ecological potential ecological hazard of water heavy metal, such as Hg、Cr、As、Zn、Pb. The result shows that in the dry seasons, about water heavy metal potential ecological hazard, from high to low the order was Cr>As>Pb; on the other, in the rainy season, the order was Cr>Pb> Zn. Then, we calculated the economic losses inside in urban and rural connection area in chongqing. It was about 1.08*10⁹ Yuan per year, and it was 4.29% of total production value of rural industry. Plus the potential ecological losses and agriculture production losses, it up to 3773723.2*10⁴～66093601*10⁴ Yuan per year. Compared to gross profit of rural industry, it was 34 times, and up to 77.5% of total rural industry output.
