英文摘要	Accurate analysis on the speciation of heavy metals in sediment may be affected by pretreatment methods．In this study，twelve surface sediment samples were collected from Jiehe Ｒiver，Jiaolai Ｒiver，Yellow Sea and Bohai Sea etc．to investigate the influences of 3 pretreatment methods (fresh preservation，naturally air-drying and freeze drying) on speciation of cadmium ( Cd) in river and ocean sediments by utilizing the Tessier five-step sequential extraction method．The results showed that the different pretreatment methods had significant influences on the speciation of Cd in sediment． The deviation of content of each speciation of Cd in the fresh preserved samples from the true values was huge; the deviations of contents of carbonate-bound and ferro-manganese oxidation speciation in naturally air-drying samples from the true values were huge，but the contents of others were close to the true values; the content of each speciation of Cd in freeze drying samples was lower，but the contents of most of Cd speciations in marine sediments were more close to the true values． The results indicated that the naturally air drying method was suitable for treatment of Cd in river sediments，while the freeze drying method was appropriate for treatment of marine sediments．
