英文摘要	The geochemical characteristics and potential controlling factors of colloidal Zn, Cd, and Pb in Huanghe (Yellow) River estuary (HRE), China were investigated. The three metals were highly variable over a range of spatiotemporal scales, comprehensively forced by various physical and biological processes. Total dissolved Zn, Cd, and Pb varied from 200.1 to 321.7, 2.6 to 4.1, and 0.5 to 1.0 nmol/L, respectively. Only one near-estuarine station of Zn had contamination factor values >1, which indicate the lower contaminant levels. Five dissolved species of Zn, Cd and Pb were fractionated, namely <1 kDa, 1-3 kDa, 3-10 kDa, 10-100 kDa, and 100 kDa-0.45 mu m. The <1 kDa truly dissolved phase was the main fraction of the three dissolved metals (50%-62%), while the 100-kDa-0.45-mu m high molecular weight colloidal fraction was dominant in their respective colloidal phase. Territorial input and sediment acted as important sources of strong ligands and natural colloids for the HRE water system. <3-kDa Zn and Pb were susceptible to the dissolved oxygen, the behaviors of colloidal Zn and 3-10-kDa Pb were related to dissolved organic carbon (DOC). However, no significant correlation between each dissolved fraction of Cd and salinity, pH, temperature, colloidal organic carbon, and DOC was found in this study. Overall, these findings, completed by the evaluation of the dissolved species of Zn, Cd, and Pb at 10 sites over the river-sea mixing zone, provided new insights into the colloidal heterogeneity that affect metals geochemical features, migration and fate in estuaries.
