Research status and prospect of microplastics in ship grey water
Summary
This review examines microplastic pollution in ship grey water, covering potential sources, current management measures, and progress in qualitative and quantitative analysis techniques for characterizing marine grey water microplastics. The authors propose future research directions including standardized analytical frameworks and improved estimation methods for marine plastic inputs from vessels.
This paper deeply discusses the microplastic pollution of ship gray water which is getting more and more attention at present. This paper begins with an overview of the potential sources of microplastics and the current management measures. Then, the research progress on the qualitative and quantitative analysis techniques of Marine gray water microplastics, Marine input estimation and type distribution of microplastics in domestic and foreign literature is reviewed in detail. On this basis, the paper puts forward suggestions for future research directions, including establishing the analysis method of gray water composition based on actual ships, strengthening the research on the basic data of microplastics, formulating the inventory of gray water microplastics discharge from ships, and promoting the improvement and development of the control policy of gray water discharge from ships. These suggestions aim to provide scientific basis and strategic guidance for the treatment of ships' grey water microplastics pollution.
