Abstract:Concentrations of heavy metal (Cu, Pb, Zn, Cr, Cd, As, Hg) were determined in the surface sediment of the Yellow River Estuary wetland during the dry (2009 April) and flood seasons (2009 June). The average concentrations of Cu, Pb, Zn, Cr, Cd, As, Hg were: (22.1±5.2), (53.8±7.6), (78.4±13.2), (60.5±8.9), (0.250±0.099), (7.7±2.7), (0.055±0.039)μg/g, respectively. The concentrations of the heavy metals were in the medium level in domestic wetlands, lower than those of the developed countries wetland in Europe and America. The distribution of heavy metals was mainly controlled by the variation of organic matter in dry season. Concentrations of Cu、Zn in dry season and As、Hg in flood season correlated well with the fine particles.
