Microplastics pollution in tropical estuary (Muttukadu Backwater), Southeast Coast of India: Occurrence, distribution characteristics, potential sources and ecological risk assessment

Scientists surveyed microplastic contamination in the water and sediments of a tropical estuary on India's southeast coast. They found moderate to high levels of microplastic pollution, with common polymers like polyethylene and polystyrene contributing the most to ecological risk. The presence of trace metals on microplastic surfaces suggests these particles may also serve as carriers for heavy metal contamination in coastal ecosystems.

Ecological assessment of microplastic contamination in surface water and commercially important edible fishes off Kadalundi estuary, Southwest coast of India

Researchers documented microplastic contamination in both the surface water and 12 commercially important fish species from the Kadalundi estuary in India. Fibers were the most common type of microplastic found, with contamination levels varying across fish species. The findings are significant because this estuary is Kerala's first community reserve, and the contaminated fish are widely consumed by local populations.

Ecological footprint of microplastics in coastal and estuarine environments of India: Sediment-water interface analysis

This study mapped microplastic pollution across 16 coastal and estuarine sites along India's coastline, finding contamination everywhere with concentrations varying based on local human activities like port operations, tourism, and fishing. The microplastics were mostly small fibers and fragments under 500 micrometers, and certain plastic types were especially good at absorbing heavy metals. This means microplastics in coastal waters serve as carriers that can transport toxic metals into the seafood chain and ultimately into human diets.
