ClearAn Integrated Spatial Assessment of Macro-, Meso-, and Microplastic Pollution Along Cox’s Bazar Beach in Bangladesh
Researchers conducted the first comprehensive assessment of macro-, meso-, and microplastic pollution along the full coastline of Cox's Bazar in Bangladesh, sampling 23 stations across tourism, active, and less active beach zones. Plastic abundance varied significantly by zone and land use, with fragments and films as dominant types, reflecting Bangladesh's high plastic waste mismanagement rates.
Occurrence and spatial distribution of microplastics in beach sediments of Cox's Bazar, Bangladesh
Microplastics were found throughout beach sediments along a 36 km stretch in Bangladesh, with polypropylene and polyethylene as the dominant polymers and higher concentrations near tourist areas. This is the first study to document microplastic distribution at this site, highlighting tourism as a significant source.
Microplastic pollution in coastal Cox's Bazar, Bangladesh: Quantification, distribution, and characteristics
This study surveyed microplastic pollution along the Cox's Bazar coastline in Bangladesh, one of the world's longest beaches, finding significant contamination in both sediments and seawater with levels varying by tidal zone and beach location. Polyethylene was the most common polymer type, and scanning electron microscopy revealed weathered particle surfaces indicating long-term environmental exposure. The findings establish a baseline for microplastic monitoring in a heavily visited coastal region with limited waste management infrastructure.

Microplastic pollution along the coastal island shorelines of Bangladesh: Distribution, patterns, and abundance
This study characterized microplastic pollution on coastal island shorelines of Bangladesh, measuring particle abundance, types, shapes, and polymer composition across sites with different human use intensities. Tourist and fishing beaches showed the highest contamination, with fishing-related plastics dominating.
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.
Does tourism enhance microplastic pollution in the ecologically critical areas of Bangladesh? Evidence from Tanguar Haor, Kaptai Lake, and the Sundarbans
Researchers assessed microplastic pollution at three prominent tourist destinations in Bangladesh—Tanguar Haor, Kaptai Lake, and the Sundarbans—finding 3–25 particles per liter, with PETE most common and contamination levels correlating with tourism activity and proximity to human pollution sources.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
From beaches to mangroves: Spatiotemporal mapping and risk profiling of microplastics in coastal Bangladesh
A comprehensive survey of microplastic contamination along the entire coastline of Bangladesh found plastic particles at all 18 sampling sites during both monsoon and winter seasons, with polypropylene, polyethylene, and polystyrene making up the majority of the material. Concentrations averaged 385–471 particles per 100 grams of sediment, and ecological risk assessments classified most sites as ranging from "danger" to "extreme danger" for marine life. Bangladesh's densely populated and heavily plastic-polluted coast represents a serious environmental hotspot requiring urgent monitoring and management.
Spatiotemporal distribution of microplastic debris in the surface beach sediment of the southeastern coast of Bangladesh
A spatiotemporal analysis of microplastics in beach sediments across 7 coastal sites in Bangladesh found an average concentration of 242 particles per kilogram dry weight, with significant seasonal and spatial variation driven by monsoon patterns and proximity to urban areas.
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.
Abundance and characteristics of microplastics in sediments from the world's longest natural beach, Cox's Bazar, Bangladesh
