“…Sua degradação ao longo do tempo forma os chamados microplásticos, que podem ser facilmente ingeridos por diversos organismos da fauna marinha. A baixa densidade do plástico é uma característica fundamental para o seu transporte para o meio aquático, pois são facilmente levados pelas correntes marítimas mesmo quando estas estão fracas (KRISHNAKUMAR, 2020). Tal qual o plástico, o poliestireno expandido, componente estrutural do isopor, apesar de ter representado baixa proporção, é um material que também se fragmenta e se espalha facilmente pelo oceano, causando danos a alguns animais que o confundem com alimento ou acidentalmente o ingerem.…”

“…Secondary microplastics are microscopic plastic particles that are produced as larger plastic garbage breaks down, both on land and in the sea [28,29]. The underlying stability of plastic trash can be compromised over time by a confluence of physical, chemical, and biological processes, leading to disintegration [30,31]. Long-term exposure to sunlight can cause photodegradation of plastics: the polymer structure oxidizes when exposed to the sun's UV radiation and induces depolymerization in polymers [32,33].…”

Microplastics have become so pervasive that they seem to be present all around us due to the significant environmental threat they pose. Microplastic pollutants have become an issue as global plastic manufacturing has increased. Microplastics are plastic wastes with particulates less than 5 mm in size that are absorbed by sediment, water, the atmosphere, and living beings before affecting health. Moreover, there is a shortage of knowledge on the distribution, sources, toxic effects, analytical techniques, and removal technologies of microplastics. This review examines the distribution and global abundance of microplastics in aquatic and terrestrial environments, analytical methods, remediation technologies, and health risks. The following are included in this review article: (1) sampling, extraction, and analysis techniques for microplastics in sediment, water, and salt; (2) the source, global distribution, and concentration of microplastics; (3) toxicity and consequences of microplastics on human health; and (4) several methods for removing microplastics, grouped into three categories: engineered, biopolymer, and bioengineered approaches. The worldwide distribution, identification, toxic effects, and remediation technology of microplastics will benefit greatly from this review.

“…Dried samples were then thoroughly grinded using motor and pistil to prevent agglomeration of sediment grains (Sruthy & Ramasamy 2017). Duplicates of 300 g of dried samples from each site were then sieved through a series of ASTM sieves (Krishnakumar et al 2020) with pore sizes of 2 mm, 600 µm, 300 µm, and 150 µm. Density separation and organic matter removal was performed based on the method proposed by National Oceanic and Atmospheric Administration (Mausra and Foster 2015).…”

Microplastics (MPs) are gaining global attention in recent years due to its widespread distribution and potential health impacts. The present study focuses on the distribution and characterization of microplastics in the sediments and bottom dwelling organisms of Kavvayi and Kumbla backwaters of Northern Malabar region, Kerala, India. MP isolation procedure including density separation, organic matter digestion and membrane ltration followed by visual and spectral analysis using optical microscope and confocal Raman spectroscopy have been utilised for the microplastic evaluation. Microplastics of size range up to 500 nanometres were analysed and presence of MPs were detected in all samples with an average abundance of 99.5 ± 69.43 particles/ kg and 96.57 ± 29.96 particles/ kg in Kavvayi and Kumbla backwaters respectively. Raman spectral analysis con rmed about 50% of MPs to be synthetic elastomers with the remaining half encompassed by PA, PE, PEST, PU and PP. Higher abundance of MPs in the edible aquatic organisms like clams, prawns and shes con rmed the transfer of MP from the environment into living organisms envisages the need of further investigation on toxicological impacts and management strategies.
