Occurrence, Distribution, and Physical Characterization of Macro- and Mesoplastic Debris in Beach Sediments of the Sutrapada-Veraval Coast, Northwestern India
AI summary Read the abstract
Researchers surveyed two beaches on India's Gujarat coast and found a steady stream of plastic trash—especially rope, plastic pouches, and foam pieces (Thermocol)—littering the sand over eight months of monitoring. While this study looked at visible plastic chunks rather than microplastics, these larger pieces break down over time into the smaller microplastic particles that can enter seafood and drinking water, so cleaning up beach litter now helps prevent a bigger health problem later.
Plastic debris poses a significant and escalating threat to coastal ecosystems worldwide, yet baseline data from many regional shorelines remain scarce. This study assessed the abundance, distribution, and physical characteristics of mesoplastics (5 mm-2.5 cm) and macroplastics (>2.5 cm) in beach sediments along the Sutrapada-Veraval coastline of Gujarat, India, over an eight-month monitoring period. Mean macroplastic abundance was 5.94 ± 3.49 and 8.75 ± 3.77 items/m² at Somnath and Sutrapada beaches, respectively. Rope pieces dominated the macroplastic assemblage at Somnath (45.39%), whereas plastic pouches were most prevalent at Sutrapada (45.37%). Mean mesoplastic abundance was 1.04 ± 1.25 and 1.31 ± 1.36 items/m² at Somnath and Sutrapada beaches, respectively. Thermocol was the leading mesoplastic category at both sites, accounting for 24.53% at Somnath and 61.90% at Sutrapada. These findings indicate persistent plastic contamination along this economically important coastline and emphasise the need for targeted waste-management interventions and sustained long-term monitoring.

Assessment of micro and macroplastics along the west coast of India: Abundance, distribution, polymer type and toxicity.
AI summary Read the abstract
This study assessed the abundance and types of micro- and macroplastics on ten beaches along India's west coast, finding plastic in all locations with fragments being the most common form. Polymer analysis revealed polypropylene, polyethylene, and polystyrene as the dominant types, and toxicity testing indicated the plastic-contaminated sediments posed ecological risks.
Quantitative assessment of microplastic in sandy beaches of Gujarat state, India
AI summary Read the abstract
Researchers quantified microplastic contamination across 20 sandy beaches on the Gujarat coast of India, finding average abundances ranging from 1.4 to 26 MPs per kilogram of sediment, with higher concentrations at beaches under greater anthropogenic pressure. Thread/fiber morphologies were the most abundant type, and the spatial distribution reflected local population density and tourist activity.
Spatiotemporal variation of macroplastic debris on recreational beaches of Ratnagiri, Maharashtra, India
AI summary Read the abstract
Researchers tracked plastic litter on two beaches in Ratnagiri, India for a year and found that pollution nearly doubled during monsoon season, mostly from plastic bags and packaging washed in by rivers. While these beaches are cleaner than famous tourist spots like Goa and Mumbai, the trend signals that fast-growing coastal towns need better waste management now—before plastic buildup worsens and breaks down into microplastics that can enter seafood and, ultimately, our bodies.
Prevalence of Plastic Debris in Beach Sediments of Sutrapada, Saurashtra Coast of Gujarat, India
AI summary Read the abstract
This seasonal study of beach sediments at two sites on the Saurashtra coast of Gujarat, India quantified macro-, meso-, and microplastics, finding that fishing activity, small-scale fisheries, and tourism were primary contributors to plastic pollution. Fragment and fiber shapes dominated across size categories, with the study providing baseline data for formulating regional plastic waste management strategies.
