Microplastic Distribution and Seasonal Variations in Backwaters Mangrove Sediments of Sandspit Karachi
AI summary Read the abstract
Researchers documented microplastic contamination in the mangrove sediments of Sandspit, Karachi, finding that these nearly invisible particles accumulate in coastal ecosystems where they enter the marine food chain — threatening everything from bottom-dwelling organisms to the humans who eat seafood.
Micro plastic are least visible particles that cannot be observed with naked eyes therefore, becoming another immense trouble around the world which contaminate mangrove ecosystem and ultimately human health.Presence of micro plastic in food chain impacts all the animals from primary consumers to tertiary consumers, therefore the sediments are the prime source of food for benthic fauna (Primary consumer) which is essential component of marine food chain.

Microplastic Extraction, Abundance And Structure From The Sediments Of Sandspit Backwaters Mangrove Area, Karachi Pakistan
AI summary Read the abstract
Researchers found tiny plastic fragments (microplastics) buried in the mangrove sediments along Karachi's coast, with the most plastic showing up in areas reached by high tides. This confirms that human trash and waste are steadily building up in coastal ecosystems that support marine life, and since fish and seafood absorb these same microplastics, this pollution can eventually make its way into the food we eat.
Preliminary assessment of microplastic in rhizosphere and non-rhizosphere region of mangrove at four locations along Karachi coast, Pakistan
AI summary Read the abstract
Researchers assessed microplastic distribution in rhizosphere and non-rhizosphere mangrove sediments at four sites along the Karachi coast, finding 14,960 particles with slightly higher counts in non-rhizosphere zones. Beads were the most common particle type, and FTIR confirmed polyethylene and polypropylene as dominant polymers.

Researchers characterized microplastic pollution in the mangrove forests of Safwa on the Western Arabian Gulf coast, analyzing sediment samples from 15 locations to document distribution patterns, identify likely sources, and assess ecological risks to this carbon-sequestering coastal habitat.
Spatiotemporal variations of microplastics in the surface sediments of a tropical mangrove ecosystem in south-western India
AI summary Read the abstract
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.
Small microplastic particles (S-MPPs) in sediments of mangrove ecosystem on the northern coast of the Persian Gulf
AI summary Read the abstract
Small microplastic particles were documented in mangrove ecosystem sediments along the northern Persian Gulf coast, with polymer types and contamination levels reflecting regional plastic use and ocean current transport patterns. The study adds to evidence that mangrove sediments in the Middle East are accumulating microplastic pollution, threatening these ecologically important coastal habitats.
