Presence of Microplastics and Organic Pollutants in Bangladesh's Freshwater Environment: A Review
AI summary Read the abstract
This review examines microplastic and organic pollutant contamination in Bangladesh's freshwater environments, highlighting that microplastics act as vectors carrying other toxic substances into aquatic food webs. Given the heavy reliance on freshwater resources in Bangladesh, this dual contamination threat poses serious risks to both ecosystem health and human food safety.
Water pollution is an alarming concern in developing nations like Bangladesh, where the majority of people rely on water resources both directly and indirectly. Microplastics (MP) and organic pollutants (OP) have a synergistic effect on the aquatic ecosystem due to the bioaccumulation process. This review determines the most influential aspects of MP and organic pollutants on freshwater environments, which serve as sites of accumulation and habitat for biota, which are important components of food webs and play a critical role in resource management, but are still underplayed. Debris in the environment and improper waste management have harmed ecosystems all over the world. Because MP plays the role of a vector for carrying organic pollutants towards the aquatic environment. These pose a global danger due to their extensive distribution in aquatic habitats and the possible consequences of their ecotoxicological impacts. The study is based on a global critical evaluation of current literature that included 40 research articles, as well as 24 global viewpoints and 16 Bangladesh perspectives (freshwater 2, marine 8, review 4, and other 2 papers). The result showed that very few research has been conducted in Bangladesh and there is no different from the rest of the world. However, there has been a tiny but continuous effort to quantify the amount of MP and OP’s garbage and its repercussions. It has been observed that a high amount of old plastic and organic pollutants is mistreated in Bangladesh, posing a serious environmental and human health risk. Empirical research have been conducted to determine the presence and effects of MPs and OPs in the marine environment. However, the study's aim is to inspire researchers to conduct in-depth investigations into plastic pollution along with organic pollutants in freshwater system in Bangladesh.

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.

The authors identify Bangladesh's rapid urbanization and poor waste management as key drivers of its disproportionate microplastic burden.
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.
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
