Abundance of microplastics in the mangrove dominated Indian Sundarbans: A mini-review
AI summary Read the abstract
Researchers monitored microplastic concentrations in surface water and sediments across two salinity zones of the Indian Sundarbans mangrove delta, finding elevated levels linked to nearby human activity and raising concerns for one of the world's largest coastal ecosystems.
We monitored microplastics in ambient surface water and sediments in two different sectors of Indian Sundarbans during August 2023, which are significantly different in terms of salinity. The western sector of Indian Sundarbans is exposed to high anthropogenic...

Assessment of spatial distribution, sources, and ecological risks of microplastics in the estuarine and coastal regions of the northern Bay of Bengal
AI summary Read the abstract
Surveys of the northeastern Bay of Bengal found surface water MP concentrations up to 1,640 items/m³ in the Karnaphuli estuary, dominated by fiber-shaped polypropylene particles, with pollution risk indices ranging from medium to very high across estuarine and coastal zones. The high MP burden in this densely populated coastal region poses serious risks to marine biodiversity, local fisheries, and the millions of people who depend on Bay of Bengal seafood as a dietary staple.
Microplastics On Mangrove Ecosystem and Scope of Biodegradation—a Review
AI summary Read the abstract
Researchers reviewed microplastic contamination in mangrove ecosystems, finding that these productive coastal habitats are accumulating plastic pollution at concerning levels, while also identifying indigenous microbial consortia as a promising biological strategy for microplastic degradation.
Distribution and Characteristics of Microplastics in the Mangrove Sediments of Guyana, South America
AI summary Read the abstract
Scientists found microplastics, tiny plastic particles, mostly fibers, in every sediment sample they tested from Guyana's coastal mangrove forests, which protect shorelines and support local fisheries. This matters because these mangroves are a key part of the seafood supply chain, meaning the plastic contamination found there could work its way into the fish and shellfish people eat, and ultimately into our own bodies. The findings highlight the need for better plastic waste management to protect both these critical ecosystems and the food they help produce.
Abundance, distribution and characterization of microplastics in Tropical River Estuary, South East Coast of India
AI summary Read the abstract
Researchers sampled water and sediment across seven sites along the Palar River estuary in southeast India, finding that fiber-shaped high-density polyethylene microplastics dominate, likely originating from fishing gear and industrial discharge. The study establishes a contamination baseline for a multi-source river system, highlighting how riverine environments serve as highways transporting plastic pollution from inland industrial and agricultural sources into coastal marine ecosystems.
The Distribution and Characteristics of Microplastics in Coastal Beaches and Mangrove Wetlands
AI summary Read the abstract
Researchers investigated how microplastics accumulate in coastal beaches and mangrove wetlands, finding these ecosystems act as hotspots that trap plastic particles carried by ocean currents and tides, potentially threatening the marine life that depends on these sensitive habitats.
