Polymer analysis identified polyethylene, polypropylene, and nylon as the dominant types. This study provides baseline data on microplastic pollution in an understudied coastal region that supports fishing communities and marine biodiversity.
Assessment of micro and macroplastics along the west coast of India: Abundance, distribution, polymer type and toxicity.
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.
Estimation of microplastics in sediments at the southernmost coast of India (Kanyakumari)
This study estimated microplastic abundance in beach sediments at Kanyakumari, the southernmost tip of India, finding higher concentrations at harbors and tourist areas compared to residential fishing communities. The results indicate that both recreational activity and harbor operations are significant sources of microplastic accumulation on Indian beaches.
Quantitative analysis of plastic debris on recreational beaches in Mumbai, India
A quantitative survey of plastic litter on four beaches in Mumbai, India, found an average of about 69 items and 7.5 grams of plastic per square meter. The study found that small plastic fragments dominated by particle count, confirming that microplastics are a major fraction of plastic pollution even on urban tropical beaches.
Presence, Spatial Distribution, and Characteristics of Microplastics in Beach Sediments Along the Northwestern Moroccan Mediterranean Coast
Researchers surveyed fourteen beaches along the northwestern Moroccan Mediterranean coast and found microplastics in every sediment sample, averaging about 59 particles per kilogram of dry sand. Fibers were the dominant shape at nearly 78%, with tourism, fishing, and wastewater discharges identified as the most likely pollution sources. The findings indicate moderate but widespread microplastic contamination along this coastline.
Preliminary Study on Abundance of Microplastic in Sediments and Water Samples Along the Coast of Pakistan (Sindh and Balochistan)-Northern Arabian Sea
Researchers found high levels of microplastic contamination along 25 locations on Pakistan's Arabian Sea coastline, with mean concentrations of 582 particles/L in seawater and 987 particles/kg in sediment, and fibers comprising up to 99% of all detected microplastics.
Microplastic prevalence in the beaches of Puducherry, India and its correlation with fishing and tourism/recreational activities
A survey of six beaches on India's Puducherry coast found microplastic concentrations averaging 72 particles per 100g of sediment, with a strong positive correlation between fishing activity and microplastic abundance, but no significant relationship with recreational tourism. The findings suggest that fishing-related plastic waste is a more important local source of beach microplastic contamination than tourism activities.
Identification and Analysis of Microplastics in Sediments of Muzhapilangad Beach, Kannur
Researchers identified and quantified microplastics in sediment samples from Muzhapilangad Beach in Kerala, India.
