Distribution and characterization of plastic debris pollution along the Poompuhar Beach, Tamil Nadu, Southern India

Personal protective equipment (PPE) pollution driven by COVID-19 pandemic in Marina Beach, the longest urban beach in Asia: Abundance, distribution, and analytical characterization

“…Several rivers flowing from west to east transport significant quantities of plastic litter into the study area. Neelavannan et al (2022) previously attributed a large amount of plastic litter on Poompuhar beach to the inflow of the Cauvery River, which plays an important role in the deposition of plastic on the Tamil Nadu coast. The significant presence of PPE on the intertidal zone is likely the result of this litter washing up on the beaches.…”

Microplastic Analysis in Soil Using Ultra-High-Resolution UV–Vis–NIR Spectroscopy and Chemometric Modeling

“…We successfully generated three different linear regression models, one for each of the following polymers: polypropylene, polyvinyl chloride, and polyethylene. All of these are common plastics found in sedimentary environments (e.g., [19,28,29]). Each of the models has a coefficient of determination (R 2 ) above 0.9, indicating that the variance of the dependent variable is negligible.…”

“…The polymers examined were low-density polyethylene (LDPE), polyvinyl chloride (PVC), and polypropylene (PP). These three polymers were selected because they are commonly found in sedimentary environments (e.g., [19,28,29]). We also analyze which plastic polymer model performed best for individual and mixture samples.…”

Increasing Risk of Invasions by Organisms on Marine Debris in the Southeast Coast of India

“…However, its biodiversity richness is threatened by anthropogenic activities (urbanization and economic development), extreme weather events, habitat loss, pollution and invasion of non-native species (Ravi, 2011;Rameshkumar and Rajaram, 2017;Vidyasakar et al, 2020;Gunasekaran et al, 2021;Sanjai Gandhi et al, 2021;Gunasekaran et al, 2022). In the southeast coast of India, the Tamilnadu region receives the largest amount of litter (Patterson Edward et al, 2020;Vidyasakar et al, 2020;Neelavannan et al, 2022;Pattiaratchi et al, 2022). However, its impact on the marine fauna is unknown because no research has been conducted on the potential of marine litter as a dispersal vector of non-indigenous marine organisms, including invasive species.…”
