| 英文摘要 | Heavy metal contamination in mariculture sediments threatens the ecological environment and human health. Therefore, this study systematically investigated the spatiotemporal distribution, geochemical speciation, and ecological risks of Cu, Pb, Zn, Cr, and Cd in surface and core sediments of traditional mariculture areas across the Sanggou Bay, Yellow Sea. The results indicated that heavy metals in surface sediments were primarily concentrated in the central area with seasonal migratory patterns (except Cd) in the Sanggou Bay. The Cu and Pb presented an increasing and then decreasing trend, while Zn, Cr, and Cd fluctuated constantly in core sediments. And Cu, Zn, and Cr predominantly existed in residual fraction, while Cd and Pb were mainly present as acidsoluble and reducible fraction, respectively. Correlation analysis and principal component analysis revealed that Cu, Zn, Pb, and Cr showed similarities and mainly originated from local aquaculture activities, whereas Cd was closely related to atmospheric deposition. Furthermore, the pollution degree and ecological risks showed that although Cd presented the lowest concentration (0.181 mg/kg), it exhibited the highest degree of pollution (PN = 3.1) and ecological risk (RI = 1356). Overall, the environmental quality of Cu, Zn, Pb, and Cr was relatively clean in study area, but Cd posed potential ecological impacts requiring prioritized attention. This research provides a robust scientific foundation for the prevention and control for heavy metal contamination in marine aquaculture areas and sustainable development. |
