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.

Microplastics pollution load in Sundarban delta of Bay of Bengal

Researchers reviewed microplastic pollution in the Sundarban Delta of the Bay of Bengal, finding that approximately 4 million tonnes of microplastics are discharged annually into the region from rivers in India and Bangladesh. The study documented plastic accumulation in sediments, water, and aquatic organisms, with over 56 tons of plastic waste deposited after a single cyclone in 2020. The findings highlight the urgent need for stronger policy measures to protect the world's largest mangrove ecosystem from microplastic contamination.

Spatiotemporal variations of microplastics in the surface sediments of a tropical mangrove ecosystem in south-western India

Researchers studied microplastic distribution in mangrove sediments along India's southwestern coast across different seasons and found contamination present year-round. Microplastic concentrations varied seasonally, with higher levels detected during certain periods linked to monsoon runoff and human activity. The study highlights that mangrove ecosystems, which provide critical environmental services, are accumulating microplastic pollution from surrounding areas.

Microplastics in coastal blue carbon ecosystems: A global Meta-analysis of its distribution, driving mechanisms, and potential risks

Microplastic abundance in blue carbon ecosystems showed the highest concentrations in Asia, especially South and Southeast Asia, with distribution influenced by vegetation habitat, climate, and river runoff. Large fish showed significant microplastic accumulation, and the effect of microplastics on sediment organic carbon varied by ecosystem type, challenging the assumption that microplastics increase carbon sequestration.

Seasonal variation of microplastics in tropical mangrove waters of South-western India

Researchers measured seasonal variations in microplastic contamination within tropical mangrove waters in South-Western India. They found that post-monsoon concentrations were highest at 1.42 microplastics per liter, while monsoon season had the lowest levels at 0.19 per liter. Fibers were the most common particle type, with polymers including polypropylene, PET, and polyethylene identified, likely originating from local tourism, aquaculture, and marine industries.

The dual role of coastal mangroves: Sinks and sources of microplastics in rapidly urbanizing areas

Researchers studied microplastic dynamics in mangrove ecosystems along two rivers and a coastal mangrove park in China's Pearl River Estuary. They found that mangroves play a dual role, acting as both sinks that trap microplastics and sources that release them back into the environment. The study highlights that rapid urbanization significantly increases microplastic loads in these sensitive coastal ecosystems.

Abundance of microplastics in a typical urban wetland in China: Association with occurrence and carbon storage

Researchers measured microplastic contamination in a Chinese urban wetland and estimated how much carbon the plastic particles contribute to the ecosystem. While microplastic-carbon currently makes up less than 0.3% of total organic carbon in the wetland, projections suggest this could rise to over 4% by 2100 if plastic production trends continue. The study highlights that microplastics are not just pollutants but are also subtly altering the carbon balance of ecosystems.
