An assessment of microplastic contamination in beach sediment of Maharashtra State, India, with special reference to anthropogenic activities
Researchers quantified microplastic contamination across 25 beaches along the Maharashtra coast of India, finding widespread pollution with significant variation between sites. They identified microplastic concentrations correlated with anthropogenic activities near each sampling location. The study provides baseline data on coastal microplastic pollution in this densely populated region and highlights the connection between human activity and beach contamination levels.
Comparative study on the status of microplastics in different functional areas of Tuticorin, Southeast coast of India
Researchers compared microplastic abundance, composition, and associated heavy metal contamination across different functional zones (industrial, fishing, tourism) of Tuticorin coastal waters in India, finding that spatial and seasonal factors significantly affect microplastic distribution and risk.
Characteristics of microplastics in the beach sediments of Marina tourist beach, Chennai, India
Researchers conducted the first baseline study of microplastic pollution in beach sediments at Marina and Pattinapakkam beaches in Chennai, India. They identified an average of 459 and 297 microplastic particles at the two sites respectively, with polyethylene being the dominant polymer type. The study suggests that both human activities and natural coastal processes contribute to microplastic accumulation at these popular tourist beaches.
Microplastic profile and ecological risk assessment of emerging estuarine contaminants in two tourist hotspots of northern Kerala backwaters
Researchers investigated microplastic pollution in sediments and water of two tourist-heavy estuarine systems in northern Kerala, India. They found average concentrations of 187 to 259 particles per kilogram in sediments and 251 to 284 particles per liter in water, with polyamide as the dominant polymer type, indicating high ecological risk driven by tourism, fishing, and poor waste management.
Occurrence, spatial distribution, and risk assessment of microplastics in surface water and sediments of Saint Martin Island in the Bay of Bengal
Researchers surveyed microplastic occurrence in surface water and sediments around Saint Martin Island in the Bay of Bengal, finding widespread contamination with spatial distribution patterns linked to tourism and fishing activities, and conducted ecological risk assessment.
The extent of microplastic pollution along the eastern coast of India: Focussing on marine waters, beach sand, and fish
Researchers assessed microplastic contamination across water, sand, and fish from seven major beaches along India's eastern coast, finding widespread pollution dominated by polyethylene and polystyrene with hazard indices indicating potential ecological risk.
The distribution, characteristics, and potential impacts of microplastics in sediments from two tourist beaches along the northern Bay of Bengal
This study characterized microplastic contamination in sediments from two popular tourist beaches along the northern Bay of Bengal in Bangladesh, finding between 56 and 137 microplastic items per kilogram at both sites. Fibers and foam dominated, polyethylene was the most common polymer, and most particles were under 0.5 mm. The results point to tourism, industrial discharge, fishing, and river runoff as the main local sources, and provide the first baseline contamination data for this coastal region.
Quantification and polymer characterization of sediment microplastics along the Golden beach, Puri, India
Microplastics were found in beach sediments at one of India's most popular tourist beaches in Puri, with an average of 731 particles per kilogram of sediment. The presence of multiple polymer types, including polyethylene and polystyrene, reflects the diverse sources of plastic pollution at heavily visited coastal sites.
Microplastic levels on sandy beaches: Are tourism and coastal recreational activities effects really important?
Researchers assessed microplastic levels at six sites across three Argentine sandy beaches with varying tourism intensity, finding concentrations averaged 1,133 items/kg in sand and 12.7 items/m3 in seawater, dominated by PE films and PET/cotton fibers. Contrary to expectations, the highest microplastic concentrations and smallest particles were found at a low-activity 'pristine' site, suggesting river proximity and coastal drift rather than tourism are the dominant local pollution drivers.
Abundance, distribution and correlation of microplastics in Tuapejat coastal water Mentawai Islands Indonesia
Researchers found microplastics — primarily fibers, fragments, and films — in both water and sediment samples from coastal waters of the Mentawai Islands, Indonesia, with the highest concentrations linked to anthropogenic activities in this marine tourism hub.
Prevalence of microplastics in the sediments of Odisha beaches, southeastern coast of India
This first study of microplastic prevalence on beaches of the Odisha coast in southeastern India documented widespread contamination, with fiber and fragment types dominated by polypropylene and polyethylene across multiple beach sites.
Microplastic levels on sandy beaches: Are the effects of tourism and coastal recreation really important?
Researchers measured microplastic levels on sandy beaches in Portugal to determine whether tourism and recreation increase contamination. They found an average of about 1,133 microplastic items per kilogram of sand, mostly fibers and films from polyethylene and polypropylene. While tourism did influence contamination patterns, the study shows that microplastics are widespread on beaches regardless of human activity, creating potential exposure risks for beachgoers.
