| 英文摘要 | In this study, hydrological parameters, dissolved organic carbon (DOC), nutrients, and dissolved metal distribution in the coastal waters around the Shandong Peninsula (SP) were systematically explored. DOC concentration varied (196.81-691.18 mu mol L-1, avg. 345.96 mu mol L-1), with <1 kDa fraction 48-99 %, showing human impact. Dissolved metals followed the pattern of Mn > Zn > Cu > Fe > Pb > Cd. Mn (13.81-1821.60 nmol L-1, 570 times that of Cd on average) was similar to 57 % colloidal. Over 63 % of Fe, Cu, Zn, Cd, and Pb were in the <1 kDa phase. Contamination factor (CF) values were low (0-4.59). Cu (with an average CF of 0.74) was the main pollution contributor. The ecological risk (ERI) was low, but Cu contributed 44 % to the ERI. Temperature affected many metals, salinity correlated with Cd, while DO and pH had weak impacts. Under the 0-30 salinity gradient, in the total dissolved (TD) fraction, Mn, Fe, Cu, and Zn mixed conservatively with non-conservative additions in the 15-25 zones. Cd and Pb increased non-conservatively. In the 1 kDa-0.45 mu m fraction, Cd grew exponentially like Pb, and the Mn, Fe, Cu, and Zn declined with rising salinity. The <1 kDa Mn, Fe, and Cu were stable, <1 kDa Zn and Pb had no consistent trend, and <1 kDa Cd behaved similarly. DOC influenced metal fractions via organic ligands, showing organic sources, yet <1 kDa DOC had weak effects. It is suggested that NO2- may be related to the denitrification effects of Mn and Pb, while NO3- may promote metal consumption and NH4+ may promote the chelation of Cd. DIP might have been related to <1 kDa Fe, Cu, and Pb by competitive adsorption. |
