The distribution, characteristics, and potential impacts of microplastics in sediments from two tourist beaches along the northern Bay of Bengal
This study characterized microplastic contamination in sediments from two popular tourist beaches along the northern Bay of Bengal in Bangladesh, finding between 56 and 137 microplastic items per kilogram at both sites. Fibers and foam dominated, polyethylene was the most common polymer, and most particles were under 0.5 mm. The results point to tourism, industrial discharge, fishing, and river runoff as the main local sources, and provide the first baseline contamination data for this coastal region.

Unveiling microplastics pollution in a subtropical rural recreational lake: A novel insight
Researchers conducted the first detailed assessment of microplastic pollution in a rural recreational lake in Bangladesh, analyzing both water and sediment samples. They found microplastics present throughout the lake, with fragments and fibers being the most common types, likely originating from agricultural runoff and recreational activities. The study reveals that microplastic contamination extends well beyond urban waterways into rural environments that have received little scientific attention.
Microplastics pollution in Bangladesh: current scenario and future research perspective
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.
Microplastics in surface water from a mighty subtropical estuary: First observations on occurrence, characterization, and contamination assessment
Researchers documented the first observations of microplastic contamination in surface waters of the Meghna estuary in Bangladesh, finding widespread pollution that poses risks to this ecologically and economically critical subtropical ecosystem.
Microplastics pollution in the river Karnaphuli: a preliminary study on a tidal confluence river in the southeast coast of Bangladesh
Researchers found high concentrations of microplastics in the surface water and sediments of Bangladesh's Karnaphuli River, with downstream areas showing the greatest abundance, fibers as the dominant type, and polyethylene terephthalate as the most common polymer.
A novel polymer-sensitive index coupled with multivariate and machine learning modeling for microplastic risk assessment in coastal sediments of the bay of Bengal
Scientists found that popular tourist beaches in Bangladesh have much higher levels of tiny plastic particles (called microplastics) in the sand compared to less-visited areas, with some of the most dangerous types of plastics concentrated where people spend the most time. The researchers discovered that simply counting plastic particles isn't enough—the type of plastic matters more for health risks, since some plastics are more toxic than others. This research shows that heavily-used beaches need better waste management to protect both tourists and local communities from potentially harmful plastic pollution.
Extent and distribution of microplastic contamination in the benthic sediment of Turag river in Bangladesh
Researchers quantified microplastic contamination in benthic sediments of the Turag River in Bangladesh, finding widespread microplastic accumulation that poses threats to benthic communities and highlights a significant knowledge gap in freshwater sediment microplastic studies.

Researchers measured microplastic pollution in surface water and sediments from 10 lakes in Latvia, Lithuania, and Poland across spring, summer, and autumn 2023, finding that tourism pressure in lake catchment areas correlates with elevated microplastic contamination levels.
Microplastic characterization and factors influencing its abundance in coastal wetlands: insights from the world’s largest mangrove ecosystem, Sundarbans
Researchers surveyed microplastic pollution in the Sundarbans, the world's largest mangrove ecosystem, examining both water and sediment samples from 20 sites. They found microplastics at every location, with polystyrene being the most abundant polymer and fragments the most common shape. The study identified proximity to port activity and organic carbon levels as key factors influencing microplastic distribution, underscoring the vulnerability of this critical ecosystem.

Unveiling the microplastic crisis: Insights into Bangladesh's aquatic ecosystems - origins, impact, and solutions
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.
Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
