Abstract: Based on investigations of major pollutants in sediments of fishing port economic zone and adjacent waters in Haizhou bay in August, 2021, distribution characteristics of the pollutants were discussed and their ecological risks were evaluated. The results showed that the contents of petroleum, organic carbon, Cu, Zn, Pb, Cd, Cr, total Hg and As in fishing port economic zone were higher than that in their adjacent waters in Haizhou bay. The contents of organic carbon, petroleum, Zn、Cd、Cr and total Hg significantly decreased from the fishing port to the adjacent sea area, while the content of sulfide generally increased from the fishing port to the adjacent sea area. The contents of Cu, Pb and As were lowest in harbor entrance, generally increasing from the entrance to fishing port and the adjacent sea area. Petroleum in the sediments in some fishing port of Haizhou bay exceeded the national first-class sediment quality standards. The comprehensive potential ecological risk of heavy metals in investigated area were low on the whole, but the fishing port economic zone is at the medium ecological risk level, among which the total Hg and Cd potential ecological risk factors are large.
