| contents | Assessment of metals pollution in seawater and sediment from the western Xuwen offshore area, Leizhou Peninsula, China. Zeng, Hongbin Shen, Xiaolong Dong, Jian-Yu Bidegain, Gorka Wang, Xuefeng China Environmental Monitoring Water Pollutants, Chemical Geologic Sediments Seawater Metals, Heavy Metals This study evaluated metals pollution in the western Xuwen offshore area (Leizhou Peninsula, China) by analyzing seawater and sediment samples collected during summer 2021-2022. The concentrations, distribution patterns, and ecological risks of Hg, Cd, Pb, Cr, As, Cu, and Zn were assessed using water quality index (WQI), degree of contamination index (DC), geo-accumulation index (I), metals pollution index (HPI), pollution load index (PLI), and potential ecological risk index (RI). Results showed metals levels varied spatially and temporally. The WQI and DC indices indicated low seawater pollution across stations in both years, while HPI highlighted site-specific contamination in 2021. Sediment analysis revealed reduced pollution in 2022, suggesting an improvement in ecological quality. The findings emphasized the need for targeted monitoring of identified high-risk areas and inconsistencies in single-metric evaluations. Furthermore, this study provides information for evidence-based policy frameworks for regional coastal management strategies. |
