| Abstract: | Sediments is one of the important parts of many aquatic ecosystems. With the rapid development of industry, and the environment problems in the world are getting serious, sediments is also polluted by contaminant in many countries.In this article, heavy metals （particularly As, Cu, Pb, Hg） concentration in the sediments at home and abroad were discussed. Toxicity of heavy metals resuh from sediments on producers （hydrophyte）, consumers （aquatic animals） and disintegrators （microorganism） in forest ecosystems was also discussed. At last, some recommendations for future study of heavy metal pollution in sediments were proposed. |
