Microplastic pollution in the marine environment: A review

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100327 - 100327

Published: May 1, 2023

The quantity of plastic materials produced worldwide is progressively increasing. For instance, annual global production has increased from 1.5 to 390.7 million metric tons 1950 2021. Meanwhile, inefficient management strategies have resulted in huge waste disposal (i.e., the form macro-, micro-, and nanoplastics) environment a hostile manner. In particular, such uncontrollable discarding paves entrance pollution into as microplastics (μPs) after degradation macroplastics. this respect, marine environments are most typical regions prone μP pollution. These ubiquitous emerging pollutants can also adsorb other pollutants, organic materials, toxic heavy metal ions, pathogens, transfer them living organisms. main theme present study compile information on how affects ecosystem, with particular emphasis following key factors: (i) types sources μPs, particularly those entering sinks; (ii) mechanisms leading μPs' degradation; (iii) poisonous effects μPs biota humans; (iv) fate environment, including their transportation routes deposition modes, (v) recent developments characterization, separation, removal environment. presented here would be practical for developing effective risk plans.

Toxicological review of micro- and nano-plastics in aquatic environments: Risks to ecosystems, food web dynamics and human health

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 278, P. 116426 - 116426

Published: May 8, 2024

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.

Fate of microplastics in sewage sludge and in agricultural soils

TrAC Trends in Analytical Chemistry, Journal Year: 2023, Volume and Issue: 166, P. 117184 - 117184

Published: July 5, 2023

The aim of this study was to review microplastics (MPs) occurrence in sewage sludge from wastewater treatment plants (WWTPs) and assess implications application agricultural soils. Sludge is a main sink for MPs WWTPs, highlighting the importance as route environmental exposure. on fields associated with elevated MP concentrations soils, potentially affecting soil health. However, prior treatments may alter abundance properties, such shape size, subsequently risk. Knowledge gaps still exist regarding their effect (size, abundance). Further investigation needed risk exposure at explore effects health, better understand how management systems, affect properties.

Vertical distribution of microplastics in an agricultural soil after long-term treatment with sewage sludge and mineral fertiliser

Environmental Pollution, Journal Year: 2024, Volume and Issue: 356, P. 124343 - 124343

Published: June 7, 2024

Sewage sludge applications release contaminants to agricultural soils, such as potentially toxic metals and microplastics (MPs). However, factors determining the subsequent mobility of MPs in long-term field conditions are poorly understood. This study aimed understand vertical distribution soils amended with sewage comparison conventional mineral fertiliser for 24 years. The depth-dependent MP mass number concentrations, plastic types, sizes shapes were compared organic carbon provide insights into transport-limiting factors. Polyethylene, polypropylene polystyrene concentrations screened down 90 cm depth via pyrolysis-gas chromatography/mass spectrometry. additional sizes, analysed 40 using micro-Fourier transform-infrared imaging. Across all depths, numbers twice 8 times higher when was applied, a share textile-related plastics, more fibres on average larger particles than soil receiving fertiliser. Transport beyond plough layer (0–20 cm) is often assumed negligible, but substantial (42 %) (52 detected 70 sludge-amended soils. initial mobilization shape- size-dependent, because fractions fragmental-shaped relatively small increased directly below layer, not at greater depths. sharp decline total between 20 resembled that matter suggesting similar transport limitations. We hypothesize effect management, ploughing, compactness by bioturbation macropores drives over long time scales. Risk assessment should therefore account considerable displacement avoid underestimating exposure.
