Geochemical assessment of trace metals in suspended particulate matter in Dongting lake, China
The trace-metal concentration ranges in suspended particulate matter (SPM) are from 1.09 to 7231.22 μgg-1 in December 2004 and from 0.34 to 9252.08 μgg-1 in August 2005 in Dongting Lake, China.Particulate metal concentrations are higher, comparable to those reported for other moderately polluted water bodies world-wide. Particulate metal concentrations during the dry (drought) season are the same those in the wet (flood) season. The assessment resulted in geo-accumulation indices that show that the contamination of particulate metals follows the order: Cd＞Hg＞Pb＞Zn＞As＞Mn＞Cu＞Ni in the dry season, and Cd＞Zn＞Hg＞Pb＞Mn＞As＞Cu＞Ni in the wet season. In both seasons, cadmium (Cd) contamination is the worst in lower reaches of the Xiang River.
