A systematic review on microplastic pollution in water, sediments, and organisms from 50 coastal lagoons across the globe

Environmental Pollution, Journal Year: 2022, Volume and Issue: 315, P. 120366 - 120366

Coastal lagoons are transitional environments between continental and marine aquatic systems. Globally, coastal of great ecological socioeconomic importance as providers valuable ecosystem services. However, these fragile subject to several human pressures, including pollution by microplastics (MPs). The aim this review was identify summarize advances in MP research across the world. We consider peer−reviewed publications on topic published English Spanish 2000 April 21, 2022, available Scopus Google Scholar. found 57 with data abundances their characteristics 50 from around world, 58% which have some environmental protection status. number type has increased significantly since 2019. Methodological differences amongst studies MPs were nevertheless a limiting factor for wide−ranging comparisons. Most (77%) conducted single compartments, integration limited, hampering current understanding dynamics such lagoons. more abundant highly populated shores watersheds, support intensive activities. On contrary, natural protected areas had lower MPs, mostly sediments organisms. Fiber/filament fragment shapes, polyethylene, polyester, polypropylene polymers predominant. accumulated certain lagoons, or been exported sea, depending influence seasonal weather, hydrodynamics, anthropogenic typology MPs. It is advised that future should focus methodological aspects, assessment/monitoring itself, impacts, prevention measures part sound management.

Photo-oxidation of Micro- and Nanoplastics: Physical, Chemical, and Biological Effects in Environments

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(2), P. 991 - 1009

Published: Jan. 3, 2024

Micro- and nanoplastics (MNPs) are attracting increasing attention due to their persistence potential ecological risks. This review critically summarizes the effects of photo-oxidation on physical, chemical, biological behaviors MNPs in aquatic terrestrial environments. The core this paper explores how photo-oxidation-induced surface property changes affect adsorption toward contaminants, stability mobility water porous media, as well transport pollutants such organic (OPs) heavy metals (HMs). It then reviews photochemical processes with coexisting constituents, highlighting critical factors affecting MNPs, contribution phototransformation other contaminants. distinct mechanism aged pointed out, terms toxicity organisms, biofilm formation, planktonic microbial growth, soil sediment community function. Furthermore, research gaps perspectives put forward, regarding underlying interaction mechanisms natural constituents under conditions, combined fate microbiological effect photoaged especially biotransformation pollutants.
