In recent years, with the industrial and agricultural development, more and more of wastewater containing heavy metals into rivers, lakes and other water bodies, such water sediments polluted by heavy metals. Heavy metals are common pollutants of the environment and has toxic and difficult to degrade, and so easy to enrichment through the food chain, thereby endangering human health and the environment. Heavy metal deposition in the sediment, in the interference of external factors will be released into the water body, causing secondary pollution. In this paper, Xia Wan, zinc and lead heavy metals in sediment was studied to determine their physical and chemical properties, content and form there to study the release of sediment zinc and lead in the dynamics, and discusses the pH value and organic acids on Release of zinc and lead, to understand the release of heavy metals in sediment characteristics and provides the basis for developing control measures.

In this paper, sequential extraction analysis of heavy metals in the form, the results show that the sediment samples, zinc and lead are mainly in the form of iron and manganese oxidation state, and not the content of exchangeable ion state to 1%. Zinc content of the relationship of the form: Fe-Mn oxides> residual ¡Ö carbonate> organic sulfided> exchangeable ion state; lead content of the relationship of the form: ¡Ö residual iron and manganese oxidation state> Organic sulfided> carbonates> exchangeable ion state.

With the development of industry and agriculture in recent years, increasing wastewaters with heavy metals discharge into water bodies, such as rivers and lakes, resulting in the pollution of water sediments. Heavy metals, as one of the most common pollutants in environment, due to their toxicity, non degradability and food chain enrichment, endanger human health and the environment. Heavy metals deposited in the sediments will be released into the water bodies under the interference of external factors, causing secondary pollution. In this study, zinc and lead heavy metals in Xiawan sediments was determined by their physical and chemical properties, content and form. The dynamics release of zinc and lead in sediments, pH value and organic acids on zinc and lead release were investigated to understand the release characteristic of heavy metals in sediments, which provides a basis for developing control measures.
