Unveiling the sources and impacts of plastic pollution: A preliminary study at Pattinapakkam Beach, Chennai, Indiaduring Cyclone Fengal
AI summary Read the abstract
After Cyclone Fengal hit the coast of Chennai, India, researchers found the beach littered with plastic debris—mostly hard plastics and plastic film, and nearly 90% of it traced back to land-based trash rather than ocean sources. This matters because storms like this wash plastic into the sea where it breaks down into smaller weathered fragments that fish and other marine life can ingest, meaning that pollution on our streets can eventually end up in seafood and, over time, in the microplastics we consume ourselves.
Aim: This study investigates the impacts of Cyclone Fengal (December 2024) on plastic debris accumulation along the South-East coast of Tamil Nadu, India, particularly in Pattinapakkam, Chennai. It aims to understand the composition, sources and ecological implications of cyclone driven plastic pollution. Methodology: Field work focused on a 2.5 km coastal stretch using systematic grid sampling, dividing the area into 12 sites, each marked by a 5m × 5m grid (25m²), ensuring spatial variability. Visible debris larger than 25 mm were collected and categorized by material and polymer type. Statistical analysis (ANOVA) was used to evaluate spatial variation in debris accumulation. Results: The findings revealed a plastic composition of 63% hard plastics, 27% film, 2% fibres, 5% styrofoam, and 3% other polymers, with polyethylene (PE) dominating at 67.6%. Statistical analysis (ANOVA) confirmed nonsignificance with a p-value> 0.05. Debris sources were traced to land-based (89%) and ocean-based (11%) origins. Interpretation: Cyclone-induced winds, storm surges and runoff contribute to increased marine debris accumulation posing significant threats to marine biota via ingestion of weathered plastics, entanglement of fishing nets. In addition, uprooting of seaweeds disrupts ecosystems and reduces the ocean's carbon sink capacity. This study highlights the urgent need for targeted policies and waste management strategies to protect coastal ecosystems.

Impact of Fengal cyclone on spatial and seasonal variation of microplastics contamination in surface waters along the Ennore Coast, southeast coast of India
AI summary Read the abstract
Researchers found high levels of microplastic pollution in coastal waters off southeast India, with tiny plastic fragments (many smaller than a grain of rice) coming from packaging, fishing gear, and urban trash. Pollution was worse after a cyclone and heavy rains, which likely washed more plastic debris into the ocean, a reminder that these waters, where seafood is caught and eaten, may carry hidden plastic contamination that ends up on our plates.
Semi-enclosed estuarine beaches as hotspots of marine litter accumulation: integrating seasonal assessment and hydrodynamic modeling
AI summary Read the abstract
Researchers found that beaches in a river-and-bay area on India's west coast get flooded with trash—over 90% of it plastic—especially during monsoon season, when rain washes litter from cities into the water. This matters because much of that plastic breaks down into microplastics that can end up in seafood and drinking water, and the study shows poor waste management on land is the main culprit, meaning better trash systems in cities could directly reduce the plastic pollution people are exposed to through the coastal environment and food chain.
Microplastics in Indian Coastal Ecosystems: Sources, Distribution, and Ecological Impact
AI summary Read the abstract
This review pulls together a decade of research on tiny plastic particles polluting India's 7,500 km coastline, finding that microplastics are widespread in beaches, water, and sea life, with pollution levels tracking closely with nearby cities, rivers, and fishing activity. Since fish and shellfish are shown to ingest these particles, this raises real concerns for the seafood many coastal communities depend on for food and income. The paper doesn't test new samples itself, but instead synthesizes existing science to highlight where research and policy need to focus next.
Influence of 2015 flood on the distribution and occurrence of microplastic pellets along the Chennai coast, India
AI summary Read the abstract
Researchers compared microplastic pellet abundance on the Chennai coast before and after a major 2015 flood and found a threefold increase in pellet density post-flood, attributing the surge to urban river runoff carrying fresh plastic debris — demonstrating that extreme rainfall events are significant episodic drivers of coastal microplastic pollution.
Microplastic pollution and its implicated risks in the estuarine environment of Tamil Nadu, India
AI summary Read the abstract
Researchers investigated microplastic pollution across 19 estuaries in Tamil Nadu, India, measuring contamination in water, sediment, and marine organisms. They found microplastic levels were higher during monsoon season due to stormwater discharge, and estimated that local residents may ingest approximately 781 microplastic items through fish and 2,809 through shellfish annually. The study suggests that estuarine microplastic pollution poses meaningful human exposure risks through seafood consumption.
