摘要	Total contents and chemical speciation of Co, Ni, Cu, Ga, Mo, Cd, In, Sn, Sb, V, W, Tl, Bi and U in size-fractionated (< 32, 32-63 and > 63 mu m) core sediments from Jiaozhou Bay were investigated to reveal their responses to anthropogenic activities. Metal contents showed a decreasing trend with increasing grain sizes. However, the loadings of metal fraction on 32, 32-63 and > 63 mu m grain sizes were 16%, 47% and 37%, respectively. Anthropogenic fluxes and enrichment factors of metals in > 63 mu m fraction were closely linked to anthropogenic activities, with an obvious increase in upper 27 cm (1998-2015) and a slight decrease in 2009 year. Metals (especially for Cd, Co, Cu and Ni) in > 63 mu m fraction were more easily released, with the highest percentage of acid soluble form and lowest residual form. Thus, the size fraction of > 63 mu m cannot be ignored.
