This study aims at reviewing the scientific literature related to microplastic (MP) pollution in various environmental matrices in India and highlighting the research gaps for future research priorities. Currently used methods for sampling, extraction, identification, characterization and quantification of MPs were assessed, and sources, distribution, transport pathways, fate, impacts, chemical risks and MP-biota interactions in the marine and freshwater ecosystems of India were examined. Studies on the spatial and temporal transport pathways of MPs are very scarce, especially w.r.t. river discharge, anthropogenic activities, beach morphology, bottom topography, biofouling and hydrodynamics. Though some amount of baseline data of MPs at select regions along the Indian coast have been generated, the extent of MP pollution in air, major rivers and nearshore continental shelf is still poorly understood. Moreover, this study highlights an urgent need for the harmonized and standardized sampling and analytical methods for MP research, that can enable us to study the spatial and temporal comparisons around the world meaningful.

这项研究的目的是回顾与印度各种环境基质中的微生物（MP）污染有关的科学文献，并强调未来研究重点的研究空白。评估了目前使用的MPs的采样，提取，鉴定，表征和定量方法，并评估了印度海洋和淡水生态系统中的来源，分布，运输途径，命运，影响，化学风险和MP-生物群系相互作用。关于海洋议员的时空运输途径的研究非常稀少，特别是在河流排放，人为活动，海滩形态，底部地形，生物污染和水动力方面。尽管已生成了印度沿海某些地区MP的一些基准数据，但空气中MP的污染程度，主要河流和近岸大陆架仍然知之甚少。此外，本研究强调了对MP研究的统一和标准化的采样和分析方法的迫切需求，这使我们能够研究有意义的全球时空比较。
