As a group of pollutants,persistent organic pollutants(POPs),either from natural sources or anthropogenic sources,could have hazardous effect on the human health and environment.Due to their long environmental residence time and semi-volatility,they eventually opt to sin into the ocean through river runoff or atmospheric deposition and cause adverse effects on marine ecology.The East China Sea(ECS),one of the China marginal seas,is located near highly developed regions of Yangtze River Delta(YRD).Strong influenced by the East Asian monsoon,ECS is the main pathway of Asian dust to the pacific and the water/atmosphere of ECS can accept amount of POPs annually.Besides,the Yangtze river could release POPS to the ECS atmosphere by evaporation.Nowadays,the ECS has been recognized as a key domain to explore the atmospheric environment and biogeochemical cycle.
