Analysis of petroleum hydrocarbon contaminants in sediments from spawning grounds of fish，shrimp，and shellfish in Bohai Bay （2021-2023）

Abstract：Based on the ecological environment monitoring data of sediments in the spawning grounds of fish，shrimp，and shellfish in Bohai Bay from August 2021，August 2022，and August 2023，this study employed spatiotemporal variation analysis and pollution index evaluation methods to reveal the temporal and spatial distribution characteristics and polltion status of petroleum pollutants in these sediments. It was found that，the content of petroleum pollutants in the sediments of these spawning grounds showed year-by一year increasing trend，with significant variations among different monitoring stations. Among them，stations KF620 ， KF630 ， KF650 ，KF430，and KF44O exhibited particularly prominent pollution issues. This study proposes targeted pollution control recommendations，aiming to provide a scientific basis for ecological environment protection and fishery resource management in Bohai Bay.
