| Abstract: |
| The ubiquitous micro-plastics pollution has received global attention in recent years. In this review, the sources, migration, distribution and ecological toxicity challenges of micro-plastics invarious environment matrices are discussed and evaluated.Micro-plastics mainly originate from two sources:(1) a significant direct input of primary micro-plastics and (2) secondary micro-plastics resulting from the fragmentation of larger plastic materials. Microplastics can migrate through atmospheric, freshwater, marine and terrestrial environments. In future, uniform methods for monitoring and investigating micro-plastics should be developed and combined with the source tracking technology, to explore its environmental effects. Microplastics (including additives) can be accidentally ingested by organisms, which may cause physical damage,a wide range of biological and physiological behavior and molecular effects. Micro-plastics can pose a combined toxicity to organism, owing to its role as a vector of chemical pollutants in ecosystems. Future studies on microplastics should focus on investigating their bio-accumulation and trophic transfer up the food chain by combined isotope tracing and new molecular biology techniques, especially for the potential health risk of microplastics for human. This review will provide a rationale for the ecological risk assessment of microplastics. |
