| 英文摘要 | Ecological protection and high-quality development of the Yellow River Basin has been an important national strategy of China, leading to an elevating attention on the environmental protection in the Yellow River Delta. Currently, limited information is available regarding heavy metal pollution in the western Yellow River Delta. In the present study, surface sediments/soils in two coastal wetlands named Shell Ridge Island (BKD) and Tuhai River Estuary (THRE), and an inland suburban wetland (SW) in the western Yellow River Delta and one adjacent to the Yellow River Estuary (CK) were collected and determined for heavy metal elements including Cu, Zn, Pb, As, and Cd. The mass fractions of Cu, Zn, Pb, As, and Cd ranged from 0.09 to 26.92, 4.80-66.34, 4.15-31.18, 3.09-20.58, and not detected (ND)-0.24 mg/kg, respectively, mainly similar to associated background values. Great levels of Zn, Pb, and As were detected in SW, while high amounts of Cu and Cd were detected in CK. Spatial differences of the occurrence and distribution of metal elements were observed. The mass fractions of Cu, Zn, Pb, As, and Cd were significantly positively correlated with the content of clay. Potential ecological risks of the metal elements were evaluated by calculating geoaccumulation index (I-geo) and potential ecological risk index (RI). The results of I-geo of the metals were < 0-1 suggesting the five metal elements in the study area were uncontaminated or slightly contaminated. The E-r(i) values we(r)e low (<40) for Cu, Zn, Pb, As, and Cd, and medium (40-80) for Cd observed in a small number of samples in CK. The RI values ranged from 6.13 to 66.78 (average: 37.22), indicating that the potential ecological risks caused by heavy metals in sediments were low. The results provided new and basic information for the heavy metal pollution in the western Yellow River Delta. |
