Assessment of potential ecological risk of microplastics in the coastal sediments of India: A meta-analysis

Marine Pollution Bulletin, Journal Year: 2021, Volume and Issue: 163, P. 111969 - 111969

Published: Jan. 27, 2021

Abundance, chemical composition and ecological risk of microplastics (MPs) in terrestrial marine environments have merited substantial attention from the research communities. This is first attempt to comprehend MPs sediments along Indian coast using meta-data. Polymer hazard index (PHI), pollution load (PLI) potential (PERI) were used evaluate quality sediments. Areas high PHI values (>1000) due presence polymers with scores such as polyamide (PA) polystyrene (PS). According PLI values, west India (WCI) are moderately contaminated (PLI: 3.03 15.5), whereas east (ECI) less 1 6.14). The PERI showed higher for metropolitan cities, river mouths, fishing zones remote islands.

Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review

Frontiers in Microbiology, Journal Year: 2021, Volume and Issue: 12

Published: April 22, 2021

Microplastics (MPs), tiny particles broken down from larger pieces of plastics, have accumulated everywhere on the earth. As an inert carbon stream in aquatic environment, they been reported as carriers for heavy metals and exhibit diverse interactive effects. However, these interactions are still poorly understood, especially mechanisms driving how pose risks living organisms. In this mini review, a bibliometric analysis field was conducted then were examined, emphasizing important roles microorganisms interactions. Their combined toxic effects potential hazards to human health also discussed. Finally, future research directions suggested. This review summarized recent progress highlighted essential microbes between MPs with hope promote more studies unveil action reduce/eliminate associated MP presence.

Microplastics in different environmental compartments in India: Analytical methods, distribution, associated contaminants and research needs

TrAC Trends in Analytical Chemistry, Journal Year: 2020, Volume and Issue: 133, P. 116071 - 116071

Published: Oct. 22, 2020

This study aims at reviewing the scientific literature related to microplastic (MP) pollution in various environmental matrices India and highlighting research gaps for future priorities. Currently used methods sampling, extraction, identification, characterization quantification of MPs were assessed, sources, distribution, transport pathways, fate, impacts, chemical risks MP-biota interactions marine freshwater ecosystems examined. Studies on spatial temporal pathways are very scarce, especially w.r.t. river discharge, anthropogenic activities, beach morphology, bottom topography, biofouling hydrodynamics. Though some amount baseline data select regions along Indian coast have been generated, extent MP air, major rivers nearshore continental shelf is still poorly understood. Moreover, this highlights an urgent need harmonized standardized sampling analytical research, that can enable us comparisons around world meaningful.

Microplastics pollution in the Brahmaputra River and the Indus River of the Indian Himalaya

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 789, P. 147968 - 147968

Published: May 24, 2021

Rivers act as temporary sinks of microplastics and a key medium allowing to enter the ocean. In this study, pollution in river shore sediment Indian Himalaya, including Brahmaputra River Indus was discussed. Sampling campaigns were performed years 2018 2019. Sample pretreatment using Na2WO4·2H2O for density separation H2O2 oxidation organic material. Microplastics analysis by FTIR microscope. The smaller size 20–150 μm more abundant (531–3485 MP/kg 525–1752 River) than range between 150 5 mm (20–240 60–340 River). found sediments all sampling sites. Fragmented, secondary dominant Himalaya. This study contributes towards filling research gap India's freshwater source highlights importance in-depth complete studies rivers that pathways microplastics.
