Distribution of plastic litter in beach sediments of Silver beach, Cuddalore, during Nivar Cyclone – A first report

Multi‐scalar interactions between mismanaged plastic waste and urban flooding in an era of climate change and rapid urbanization

“…In some cases, previously deposited plastic waste can remobilize during floods (Harris et al, 2021). Increased heavy rainfall flushes out previously buried or stuck micro‐ and macro‐plastics, with the resulting plastic waste apparent on beaches and in coastal areas (Gandhi et al, 2021; Hurley et al, 2018). Studies show that hydrometeorological conditions play an important role in the fate and transport of plastics in river systems and estuaries, where plastics gets stranded on riverbanks, sometimes remobilizes or flushes out into the ocean (Tramoy et al, 2020; van Emmerik et al, 2022).…”

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

“…The study area is densely populated by various major and minor chemical-based industries, involved in mineral and metal processing, oil refinement, pharmaceutical, dye and fertilizer production. It also receives a large amount of debris from recreational, fishing and tourism activities (Dowarah and Devipriya, 2019;Jeyasanta et al, 2020;Sanjai Gandhi et al, 2021;Gunasekaran et al, 2022;Kannan et al, 2023a) and from international shipping from Southeast Asian countries (Dharani et al, 2003). Climate in the area is tropical, with temperatures between 20.5 and 37.8 • C and high rainfall from northeast during the monsoon season (November to February, average precipitation over the period 698 mm).…”

“…Furthermore, the IUCN endangered species, such as olive ridley (Lepidochelys olivacea (Eschscholtz, 1829)) and green turtle (Chelonia mydas (Linnaeus, 1758)), are frequently occurring along this coast (Chandrasekar and Srinivasan, 2013). 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).…”
