| Abstract: |
| Microplastics refer to those plastic fibers,fragments or particles less than 5 mm in diameter,which have a wide range of sources and stable properties in the environment.They are ideal carriers for hydrophobic organic pollutants and heavy metals.Microplastics are easily ingested by plankton,fish and lower organisms,and transferred and enriched between trophic levels in the food web.As a new type of environmental pollutants,microplastics have posed a serious threat to the ecological environment,resulting in potential risks to food safety.Microplastics analysis techniques are the basis for research of microplastics distribution,migration,transformation,fate and ecological toxicological effects in the environment.The research progress of microplastics collection,separation,extraction and qualitative identification in environmental samples at home and abroad is reviewed in this paper,and the advantages and disadvantages of each method are discussed.Finally,aiming at the problems and shortcomings of microplastics analysis methods at present,the future development trend of analysis techniques for environmental microplastics is forecasted. |
