The ecological impact of white pollution from offshore fisheries and aquaculture on coastal areas

Based on the rapid development of offshore fisheries and aquaculture in recent years, this paper focuses on the increasingly serious pollution and destruction of the ecological environment, especially the serious problem of white pollution represented by microplastics. The author of this article focuses on the study of microplastic white pollution and analyzes and studies the surface sediments of aquaculture waters in Zhoushan Islands, Zhejiang, and Maowei Sea, Guangxi, as well as typical tidal flats around them. Compare by collecting data on surface sediments, microplastics on tidal flats, and microplastic types in nearby tidal flats from two locations. The microplastics in the two regions are divided into fragments, fibers, foams, and films based on their appearance and shape. The proportion of fibers is the highest, and the particle size of microplastics is mainly below 1mm. The color of microplastics is mainly lighter, with the highest amount of white. The chemical components of microplastics include polyester, polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyamide. The research results are helpful for routine marine biological surveys and can serve as a basis for evaluating marine debris, especially microplastics
