摘要
根据2021年8月、2022年8月和2023年8月渤海湾鱼虾贝类产卵场沉积物生态环境监测数据,通过时空变化分析法和污染指数评价法,揭示了渤海湾鱼虾贝类产卵场沉积物中石油类污染物的时空分布特征及其污染状况。研究发现,渤海湾鱼虾贝类产卵场沉积物中石油类污染物含量呈现逐年上升趋势,且在不同站位之间存在显著差异,其中KF620、KF630、KF650、KF430和KF440的污染问题较为突出。本研究提出了有针对性的污染控制建议,以期为渤海湾生态环境保护和渔业资源管理提供科学依据。
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 pollution 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-year increasing trend,with significant variations among different monitoring stations.Among them,stations KF620,KF630,KF650,KF430,and KF440 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.
