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.
