摘要

 This paper aims to investigate the concentration, partitioning and sources of As in the major rivers of eastern China.Samples of filtered water and suspended particulate matter were sampled, from more than 30 rivers at the lower reaches in 2007 and 2008. The results indicated that the concentration of dissolved As is averaged to 3.1 μg/L, significantly higher than most other rivers in the world. The frequency distribution histogram with more than one peak showed that most of the rivers have been obviously polluted by anthropogenic activities, which was also confirmed by the enrichment factors (EF) of the suspended particulate matter samples. The sources of anthropogenic pollution of typical rivers were presumed mainly coming from industrial and domestic waste water.
