“…The NPI is classified into non-pollution (<1), low (1-2.5), moderate (2.5-7), and high degree of pollution (>7). The EF is classified into nil (<1), minor (1-3), moderate (3-5), significant (5-10), and severe enrichment (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). The I geo is divided as follows: (<0) unpolluted, (0-1) unpolluted to moderately, (1-2) moderately, (2-3) moderately to strongly, (3-4) strongly polluted, and (4-5) strongly to extremely polluted.…”

“…Determining the pollution status of fishing ports will help the planning of facilities, construction activities, formulation of management regulations, and control of pollution sources [16,17]. Fishing port sediments worldwide have been significantly contaminated with heavy metals [17][18][19][20]. Routine maintenance of fishing vessels and wastewater discharges may potentially be the primary sources of heavy metals in fishing port sediments.…”

Routine maintenance of fishing vessels and wastewater discharges are primary sources of heavy metals in fishing ports. Sediment pollution assessment is necessary in fishing port management, including sediment dredging and disposal, sewage treatment facility construction, and pollution source control. In this study, sediment heavy metal contents in Qianzhen Fishing Port, the largest pelagic fishery port in Taiwan, were investigated to assess the contamination levels and related potential ecological risks using multiple sediment pollution indices. Normalization methods were applied to identify the potential sources of heavy metals in fishing port sediments. Results showed that Cu, Zn, Pb, and Cr contents in the sediments of the inner fishing port (averages of 276, 742, 113, and 221 mg/kg, respectively) were 3–5 times greater compared to those along the port entrance and outside, indicating the strong impacts of anthropogenic pollution (EFCu: 5.6–12.5; EFZn: 2.8–4.3; EFPb: 2.4–5.4; EFCr: 1.1–3.2). Copper pollution was more severe, with high maxima contamination factor (CFCu: 15.1–24.8), probably contributed by copper-based antifouling paints used in fishing vessels. The sediments in the inner fishing port are categorized as having considerable ecological risk and toxicity (mERMq: 0.61–0.91; ΣTU: 7.5–11.7) that can potentially cause adverse effects on benthic organisms. Qianzhen Fishing Port sediments can be characterized as high Cu/Fe and Pb/Fe, moderate Zn/Fe, and high total grease content, indicating that the potential sources of heavy metals are primarily antifouling paints and oil spills from the fishing vessels. This study provides valuable data for pollution control, remediation, and environmental management of fishing ports.
