Fishing ports are among the environments that accumulate pollutants along the coast but often lack environmental data and scientific research. This study investigated 8 metals, 16 polycyclic aromatic hydrocarbons (PAHs), 10 phthalate esters (APs), and 2 alkylphenols (APs) in the surface sediments of Qianzhen Fishing Port, the largest pelagic fishing port in Taiwan. Indicator compounds, pollution hotspots, potential ecological risk levels, and pollution sources were evaluated. Results showed that copper, zinc, and bis(2-ethylhexyl) phthalate (DEHP) in surface sediments were pollution indicators posing potential toxicological risks. Metals and PAHs in sediments were mainly from ship-related sources, while PAEs and APs were related to dockland activities. Combining metal and organic pollutants, the sediments had a moderate potential ecological risk, with metals higher than organic pollutants. Cluster analysis and color geographic map of risks indicate sediment pollution hotspots and areas requiring immediate intervention. In the future, sustainable operation and management can be carried out by using metal-free antifouling paint, improving sewage treatment rate, and regular environmental dredging of fishing port.
渔港是沿海地区污染物积聚的环境之一，但往往缺乏环境数据和科学研究。本研究调查了台湾最大的外海渔港前镇渔港表层沉积物中的 8 种金属、16 种多环芳烃（PAHs）、10 种邻苯二甲酸酯（APs）和 2 种烷基酚（APs）。评估了指示化合物、污染热点、潜在生态风险水平和污染源。结果表明，表层沉积物中的铜、锌和双（2-乙基己基）邻苯二甲酸酯（DEHP）是具有潜在毒理学风险的污染指标。沉积物中的金属和多环芳烃主要来自与船舶相关的来源，而邻苯二甲酸酯和烷基酚则与码头活动有关。结合金属和有机污染物，沉积物具有中等的潜在生态风险，金属的风险高于有机污染物。聚类分析和风险的色地理图表明了沉积物污染热点和需要立即干预的区域。未来，可以通过使用无金属防污漆、提高污水处理率和定期对渔港进行环境疏浚来进行可持续的运营和管理。
