Unveiling the microplastic crisis: Insights into Bangladesh's aquatic ecosystems - origins, impact, and solutions
AI summary Read the abstract
This review examines the growing microplastic crisis in Bangladesh's rivers, estuaries, and coastal waters, finding that the country's rapid urbanization and limited waste management have led to widespread contamination. Microplastics were documented in water, sediment, and fish across multiple Bangladeshi water systems. Since over 160 million people in Bangladesh depend on these water resources for drinking, farming, and fishing, the contamination poses a significant public health concern.
Microplastics (MPs) are an increasingly concerning type of environmental pollutant due to their abundance and the potential for bioaccumulation in aquatic food organisms. The presence of MPs in the natural waters is a clear indication of the incorrect disposal of plastic debris and the rapid growth of synthetic plastic production. An inclusive understanding of the sources, transportation, fate, and consequences of plastic waste is crucial for accurately estimating the global transit of plastic pollution and reducing its sources and hazards. Bangladesh is a significant contributor to global plastic pollution, and this review aims to summarize the existing knowledge and research gap on MP pollution in aquatic ecosystems in Bangladesh over the past five years. This article discusses the features, occurrence, and potential hazardous effects of MPs on aquatic organisms and humans to provide innovative approaches for sustainable remediation. It emphasizes the importance of a multidisciplinary approach to reducing plastic inputs into the aquatic environment, including regulation on production and consumption of plastics, using bio-based and biodegradable plastics, improving plastics life cycle, eco-friendly design for production, extended producer accountability over waste management, prioritizing recycling, creating demand for recycled plastics, and improving waste collection and management systems. The study purposes further research into plastic pollution in Bangladesh, explore environmentally friendly plastic substitutes, and provide decision-makers with effective strategies to address the plastic pollution problem in Bangladesh.

Microplastics have been found throughout Bangladesh's aquatic and terrestrial environments, where they threaten biodiversity and enter the food chain. This review synthesizes the available evidence and calls for stronger national monitoring programs and policies given Bangladesh's vulnerability to plastic pollution from its dense population and major rivers.
Microplastic Pollution in Bangladesh: A Review of Ecological and Biochemical Impacts
AI summary Read the abstract
This review summarized the current state of microplastic pollution in Bangladesh, covering occurrence across water, soil, seafood, and air, as well as documented ecological and biochemical health impacts. The authors identify Bangladesh's rapid urbanization and poor waste management as key drivers of its disproportionate microplastic burden.
Microplastic Pollution in Bangladesh: A Structured Review of Sources, Impacts, and Policy Responses
AI summary Read the abstract
This review pulls together existing research on microplastic pollution in Bangladesh's rivers, lakes, and coastal waters, showing that tiny plastic fragments from textiles, industry, and everyday waste are building up in water and food sources like fish. Since people are exposed to microplastics mainly by eating contaminated food (and possibly breathing them in), this matters because it means plastic pollution isn't just an environmental issue, it's likely entering our bodies through the food chain. The authors call for stronger policies, like banning single-use plastics and improving waste management, to reduce this exposure before more is understood about its long-term health effects
Microplastics pollution in aquatic ecosystems of Bangladesh — A critical review on research trends and future perspectives
AI summary Read the abstract
This review found widespread microplastic contamination across all aquatic compartments in Bangladesh, with average concentrations of 4.92 particles/L in water and 118.40 particles/kg in sediment. Polyethylene, polypropylene, and polystyrene fibers and fragments predominated, with freshwater fish accumulating the most microplastics per organism.
