Micro- and nanoplastics (MNPs) are widespread emerging contaminants with many potential direct indirect effects on soil ecosystems. Ecological MNP hazard assessment is thus crucial for a proper risk the development of environmental protection regulations. However, current testing approaches hampered by absence guidelines, harmonization, standard reference materials. This article discusses need improving provides specific recommendations to increase relevance reliability ecotoxicity data. Our focus environmentally relevant experimental designs, guidelines microplastic test materials selection characterization, analysis MNPs additives in biota, proposal physicochemical properties be assessed during testing. brings novelty field ecological providing solutions much needed this field.

Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants

Environmental Quality Management, Год журнала: 2024, Номер 34(1)

Опубликована: Июль 17, 2024

ABSTRACT Microplastics (MPs), which are emerging pollutants in terrestrial ecosystems, could potentially impact plant growth. One of the least explored aspects crop development is seed germination, a crucial stage plant's lifecycle. This study conducted soil cultivation trials to investigate effects 1% (w/w) concentrations polyethylene (PET), polypropylene (PP), and polystyrene (PS) MPs on rice growth over 15‐day period. Parameters such as fresh weight, shoot height, root length, chlorophyll levels, identification roots were observed. The findings revealed accumulation 6–9 MP items roots. PET inhibited elongation (15%–20%), reduced height (15%–30%), decreased weight (12%–37%). PET, PP, PS contamination content (15%–43%), b (21%–41%), total (11%–40%) leaves. enhances our understanding ecotoxicological these three types rice. utilization this data will further inform MPs' behavior vegetation provide valuable insights into their land‐based impacts.

The fate of post-use biodegradable PBAT-based mulch films buried in agricultural soil

The Science of The Total Environment, Год журнала: 2024, Номер 948, С. 174697 - 174697

Опубликована: Июль 15, 2024

The fate of black biodegradable mulch film (MF) based on starch and poly(butylene-adipate-co-terephthalate) (PBAT) in agricultural soil is investigated herein. Pristine (BIO-0) UV-aged samples (BIO-A192) were buried for 16 months at an experimental field southern Italy. Visual, physical, chemical, morphological, mechanical analyses carried out before after burial. Film residues the form macro- microplastics analyzed end trial. Progressive deterioration both pristine samples, with surface loss alterations properties, occurred from 42 days After 478 days, apparent BIO-0 BIO-A192 films decreased by 57 % 66 %, respectively. Burial determined a rapid depletion polymeric blend, especially BIO-A192, while degradation polyester phase was slower. Upon burial, enrichment aromatic moieties PBAT observed, as well release to soil. analysis MF products extracted (0.006–0.008 mass samples) revealed predominant presence adipate moieties. about 23 17 initial amount respectively, This comprehensive study underscores complexity biodegradation phenomena that involve new generation field. different biodegradability components, climate, conditions did not strictly meet parameters required standard test method devised MFs, have significantly influenced their rate. finding further emphasizes importance implementing experiments accurately assess real effects MFs health overall agroecosystem sustainability.

Ecotoxicological effects and detection features of polyvinyl chloride microplastics in soils: A review

Environmental Advances, Год журнала: 2023, Номер 13, С. 100437 - 100437

Опубликована: Окт. 1, 2023

The soil microplastics pollution problem is becoming more and urgent every year. PVC a widely used material, consequently it possible that are significant contributor to pollution, especially in industrial soils. At the same time, usually contains many different chemical additives have ability migrate surface during aging. This review devoted summarizing results of studies on prevalence, ecotoxicological effects, features analytical process for detection microplastics. There evidence adversely affect ecosystem by leaching harmful substances with aging, affecting some animals, plants, microbial communities, enzymatic activity biogeochemical cycles. However, there insufficient data this issue further research needed. approaches analytics steps containing microplastics, its as well complexity matrix, must be taken into account when selecting protocol. It necessary strive standardization protocol comparable data.

Microplastics pollution modulating soil biological health – A review

Soil Use and Management, Год журнала: 2025, Номер 41(1)

Опубликована: Янв. 1, 2025

Abstract Microplastics (MPs) reach the soil environment through application of recycled water, biosolids, and compost in‐situ weathering plastic mulch used in agriculture. This review provides an overview sources MP input to their interactions with biota, thereby impacting biological health. MPs contain various chemical additives can be ingested by activity function. also serve as a vector for inorganic organic contaminants. These environmental contaminants released into porewater during impact biota. Overall, alter soil's physical properties habitat microorganisms. Soil microorganisms use carbon source porous proliferation. Future research needs focus on genomic functional diversity microbes impacted contamination, enabling us develop strategies mitigate impacts

The prevalent presence of microplastics in marine environments poses major ecological risks requiring innovative approaches to their management and reduction. This study addresses a knowledge gap biodegradable microplastic alternatives by looking at the biodegradability properties reclaimed polypropylene (PP) blended with polylactic acid (PLA). lies systematic exploration various PP/PLA formulations, evaluating potential for enhanced without significantly compromising mechanical performance. Microplastic PP PLA blends were prepared ratios using melt blending method. blend was characterized Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) confirm morphology components. evaluated tensile strength tests. A 90% 10% found retain highest even after immersion seawater. thermal stability degradation behavior analyzed differential calorimetry (DSC) thermogravimetric analysis (TGA). shows that increasing content affects blends. Seawater soil burial tests used assess results showed blends’ biodegradation confirmed increases conductivity salinity seawater weight loss burial. findings show improves while maintaining adequate properties. Tests including saltwater Finally, this presents new approach reducing pollution through PLA, resulting sustainable material improved environmental Future studies should look into polymers, long-term under variety circumstances.
