Research on the Characteristics and Influencing Factors of Microplastic Pollution in Coastal Beaches of Eastern Hebei Province
Coastal beaches are important areas for the accumulation and exposure of microplastics,and are widely present on sandy beaches.This study takes the famous Qinhuangdao Shallow Bay Beach,Changli Golden Coast Beach,and Tangshan Xiangyun Bay Beach in Hebei province as examples to explore the pollution characteristics and influencing factors of microplastics on beaches.By collecting 12 beach samples for analysis,it was found that the abundance of microplastics in the beaches of Shallow Water Bay,Golden Coast,and Xiangyun Bay was at a relatively low level.Black was the common color of microplastics in the three beaches,and fibrous was the main shape of microplastics.The particle size was mainly distributed between 500 and 2000 μm.The polymer composition was mainly artificial silk,and there was also a certain amount of chlorinated polyethylene in the beaches of Shallow Water Bay.From the statistical results,it can be seen that the abundance of microplastics is mainly influenced by human factors such as tourist numbers,fishing activities,tidal dynamics,and various natural factors.The research results contribute to understanding the pollution characteristics and sources of microplastics in beach sediments,providing scientific basis for microplastic control,emission reduction,and prevention decisions.
