Microplastics (MPs), a novel form of pollution, have triggered concerns about environmental contamination worldwide and have become the focus of ongoing research. However, the lack of sufficient knowledge about the long-term impacts of MPs on Bangladesh's environment and public health inhibits the development of effective regulations and mitigating strategies. This study summarizes the sources, pathways, dispersion, and impacts of MPs in multi-environmental matrices of Bangladesh, where plastic pollution is becoming a crucial environmental problem. It assesses the existing knowledge regarding MPs in various environmental matrices, determines knowledge gaps for future research priorities, and proposes policy development for sustainable remediation. Articles regarding microplastic pollution in Bangladesh were identified through searches on various search engines using relevant keywords, resulting in 49 selected publications after filtering relevance and duplicates. The findings demonstrate that MPs in Bangladesh are predominantly fibers and fragments, originating from textile and packaging sources. The most prevalent polymers identified in Bangladesh's surface water, sediments, and biota were polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP). This review emphasizes the necessity of conducting in-depth investigations into the effects and fate of MPs, along with effective recycling and waste management techniques, to tackle this worldwide issue nationally.
微塑料（MPs）作为一种新型污染形式，已引发全球对环境污染的关注，并成为当前研究的焦点。然而，由于对微塑料对孟加拉国环境和公众健康的长期影响缺乏足够了解，阻碍了有效监管和缓解策略的制定。本研究总结了孟加拉国多环境基质中微塑料的来源、途径、扩散及影响，在该国塑料污染正成为一个关键环境问题的背景下。它评估了关于微塑料在各种环境基质中的现有知识，确定了未来研究重点的知识空白，并提出了可持续修复的政策制定建议。通过使用相关关键词在各种搜索引擎上进行搜索，确定了有关孟加拉国微塑料污染的文章，经过相关性筛选和重复项过滤后，最终选定了49篇出版物。研究结果表明，孟加拉国的微塑料主要是纤维和碎片，来源于纺织和包装行业。在孟加拉国地表水、沉积物和生物群中鉴定出的最常见聚合物是聚乙烯（PE）、聚对苯二甲酸乙二酯（PET）和聚丙烯（PP）。本综述强调有必要对微塑料的影响和归宿以及有效的回收和废物管理技术进行深入调查，以便在国家层面解决这一全球性问题。
