Microplastic (MP) release into the terrestrial environment has occurred since humans started manufacturing and using plastics. These tiny plastic particles can be found in various media, including atmosphere, soil, freshwater, sediments, organisms. MPs migrate through environmental media due to wind, water, gravity, biological processes. Although variables that affect migration process have been investigated settings, mechanisms of MP environments yet systematically characterized. This study classifies as physical, chemical manners, discusses factors affecting dynamic factors, characteristics. Examining action establish a foundation for understanding processes provide theoretical framework modeling movement environmental. Future research challenges include effect characteristics simulating long-term. Exploring on spatial temporal scales, considering life cycle is worthy direction.

A systematic review of microplastics emissions in kitchens: Understanding the links with diseases in daily life

Environment International, Год журнала: 2024, Номер 188, С. 108740 - 108740

Опубликована: Май 11, 2024

The intensification of microplastics (MPs) pollution has emerged as a formidable environmental challenge, with profound global implications. pervasive presence MPs across multitude mediums, such the atmosphere, soil, and oceans, extends to commonplace items, culminating in widespread human ingestion accumulation via channels like food, water, air. In domestic realm, kitchens have become significant epicenters for pollution. A plethora kitchen utensils, encompassing coated non-stick pans, plastic cutting boards, disposable are known release substantial quantities particles everyday use, which can then be ingested alongside food. This paper conducts thorough examination contemporary research addressing from utensils during usage focuses on health risks associated ingestion, well myriad factors influencing utensils. Leveraging insights derived this analysis, proposes series strategic recommendations measures targeted at mitigating production settings. These initiatives designed not solely diminish but also enhance public awareness regarding pressing concern. By adopting more informed practices kitchens, we significantly contribute reduction burden pollution, thus safeguarding both ecological system.

Soil Microplastic Pollution and Microbial Breeding Techniques for Green Degradation: A Review

Microorganisms, Год журнала: 2024, Номер 12(6), С. 1147 - 1147

Опубликована: Июнь 5, 2024

Microplastics (MPs), found in many places around the world, are thought to be more detrimental than other forms of plastics. At present, physical, chemical, and biological methods being used break down MPs. Compared with physical chemical methods, biodegradation have been extensively studied by scholars because their advantages greenness sustainability. There numerous reports recent years summarizing microorganisms capable degrading However, there is a noticeable absence systematic summary on technology for breeding strains that can degrade This paper summarizes strain-breeding MP-degrading first time way, which provides new idea efficient strains. Meanwhile, potential techniques bacteria MPs proposed, providing direction selecting future. In addition, this reviews sources pollution status soil MPs, discusses current challenges related emphasizes safety MP biodegradation.

Addressing the relevance of polystyrene nano- and microplastic particles used to support exposure, toxicity and risk assessment: implications and recommendations

Particle and Fibre Toxicology, Год журнала: 2024, Номер 21(1)

Опубликована: Сен. 27, 2024

There has been an exponential increase in the number of studies reporting on toxicological effects associated with exposure to nano and microplastic particles (NMPs). The majority these studies, however, have used monodispersed polystyrene microspheres (PSMs) as 'model' particles. Here we review differences between manufacture resulting physicochemical properties commerce PSMs most commonly toxicity studies.

Microplastics (MPs) and nanoplastics (NPs) both represent significant concerns in environmental sciences. This paper aims to develop a convenient efficient methodology for the detection measurement of MPs nanoparticles from surface seawater apply it water samples collected UNESCO site Venice its lagoon, more precisely Venice-Lido Port Inlet, Grand Canal under Rialto Bridge, Saint Marc basin. In this study, were analyzed through optical microscopy their relative abundance characterized based on color, shape, size classes, while concentration mean estimated via Nanoparticle Tracking Analysis technique. Bulk sampling, combined with filtration cascade stainless-steel sieves subsequent digestion, facilitates relatively small sizes (size classes distribution: >1 mm, 1000–250 μm, 250–125 125–90 90–32 μm), similar ingested by marine invertebrates fishes.

Enhancing the Phytoextraction of Cd, Cu, Pb, and Zn by Portulaca oleracea in a Heavily Contaminated Soil Using Low Molecular Weight Organic Substances: Is Phytoremediation Viable?

Earth Systems and Environment, Год журнала: 2024, Номер 8(3), С. 923 - 936

Опубликована: Апрель 22, 2024

Abstract Phytoremediation can be accelerated if contaminated soils are amended with releasing agents. We tested four such materials, citric acid (CA), EDTA, oxalic (OA), and tartaric (TA) at two doses, 20 40 mmol kg −1 , in a pot experiment to heavily soil cultivated purslane ( Portulaca oleracea ). found that Cd extracted DTPA remained unchanged all treatments compared the control except for treatment of added EDTA (“EDTA-40”). Similar was case Cu, Pb, Zn. As consequence, aboveground plant material increased significantly from 1.21 (control) 3.84 EDTA-40 3.55 EDTA-20 (mg other metals, Pb exhibiting an impressive fivefold increase 280.35 mg control. conclude most successful agent among those tested, especially However, we come conclusion that, based on calculations required time meaningfully reduce metals contents, phytoremediation is not practical option extremely metal-elevated soils. These findings should verified under field conditions.

Materials, Год журнала: 2025, Номер 18(4), С. 760 - 760

Опубликована: Фев. 9, 2025

Microplastic (MP) contamination in soil is an emerging environmental concern, influencing the mobility and bioavailability of heavy metals (HMs). This study investigates how different MP types (PP, PS, PVC, HDPE, LDPE, PES, PET-Glitter) affect HM behavior soil, focusing on sorption/desorption, extraction efficiency Pb, Cu, Co, Ni, Cr, Cd. Soil samples incubated with MPs showed significant pH increases, particularly PES HDPE at 0.8 0.6 units, respectively. The experiments using 0.05 M EDTA 0.01 CaCl2 revealed that altered metal bioavailability—with reducing Pb by 15%—and increased Cd Co 10–20%. batch sorption tests confirmed higher adsorption onto but decreased compared to control soils without MP. These findings demonstrate act as additional sites, modifying speciation availability, which has critical implications for health, agricultural sustainability, remediation strategies. However, results may vary based type, aging, conditions, indicating need further long-term field studies. research provides valuable insights into complex interactions between MPs, metals, systems, contributing a better understanding pollution dynamics risk assessment contaminated environments.
