To describe the levels and distribution characteristics of heavy metals in sediments in the main stream of Huaihe River,the papers from 1980-2009 on heavy metals in Huaihe River basin were collected and the scope,the extent and the distribution of 8 kinds of heavy metals,including chromium(Cr),manganese(Mn),copper(Cu),zinc(Zn),cadmium(Cd),lead(Pb),mercury(Hg) and arsenic(As),were analyzed in 50 sediment samples sections of Huaihe River,and were compared with the related levels in the other basins.The results showed that in sediments of Huaihe River,the average level of Cr was 63.7 mg/kg(48.2 mg/kg-123.6 mg/kg),the average level of Mn in was 719 mg/kg(439 mg/kg-1 124 mg/kg),the average level of Cu was 29.9 mg/kg(6.0 mg/kg-65.6 mg/kg),the average level of Zn was 79.2 mg/kg(39.2 mg/kg-230.1 mg/kg),the average level of Cd was 0.29 mg/kg(0.10 mg/kg-0.96 mg/kg),the average level of Pb was 29.5 mg/kg(17.3 mg/kg-72.8 mg/kg),the average level of Hg was 0.08 mg/kg(0.03 mg/kg-0.36 mg/kg),the average level of As was 12.6 mg/kg(9.0 mg/kg-21.8 mg/kg).The percentage of cross-section where the levels of heavy metals in sediments of Huaihe River were higher compared with the average of China,ranked as follows: 90.5% for As,88.1% for Cd,68.0% for Zn,66.7% for Hg,65.8% for Cu,57.6% for Mn,55.3% for Cr and 50.0% for Pb,respectively.The levels of heavy metals in Huaihe River sediments are at a relative high level compared with other river basins in China.Of them,the Cr and Mn are the most serious pollution,Cr is the second only to the content of loess sediments of the Yangtze River,Mn is the second only to the content of the Huaihe River Basin sediments.
