The “Microplastome” – A Holistic Perspective to Capture the Real-World Ecology of Microplastics

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 8, 2024

Microplastic pollution, an emerging pollution issue, has become a significant environmental concern globally due to its ubiquitous, persistent, complex, toxic, and ever-increasing nature. As multifaceted diverse suite of small plastic particles with different physicochemical properties associated matters such as absorbed chemicals microbes, future research on microplastics will need comprehensively consider their multidimensional attributes. Here, we introduce novel, conceptual framework the "microplastome", defined entirety various (<5 mm), found within sample overall toxicological impacts. novel concept, this paper aims emphasize call for collective quantification characterization more holistic understanding regarding differences, connections, effects in biotic abiotic ecosystem compartments. Deriving from lens, present our insights prospective trajectories characterization, risk assessment, source apportionment microplastics. We hope new paradigm can guide propel microplastic toward era contribute informed strategy combating important issue.

Higher potential leaching of inorganic and organic additives from biodegradable compared to conventional agricultural plastic mulch film

Journal of Hazardous Materials, Journal Year: 2025, Volume and Issue: 488, P. 137147 - 137147

Plastic mulch films support global food security, however, their composition and the potential release rates of organic, metal metalloid co-contaminants remains relatively unknown. This study evaluates low molecular weight organic additives, content leaching from density polyethylene (LDPE) biodegradable plastic films. We identified 59 non-intentionally added substances in new LDPE (39.8 mg m-2) 60 (129 m-2). The compounds high concern for ecosystem human health (e.g. phthalates, organophosphite antioxidants) was comparable to those (fatty acids, fatty amides, alkanols).

Concentration‐ and Size‐Dependent Influences of Microplastics on Soil Hydraulic Properties and Water Flow

European Journal of Soil Science, Journal Year: 2025, Volume and Issue: 76(1)

Published: Jan. 1, 2025

ABSTRACT Extensive usage of agricultural plastic film correspondingly leads to excessive residues microplastics (MPs). MP accumulation alters soil hydraulic properties and water flow. However, little is known about the combined effects concentration particle size on hydrological properties, a numerical approach for modelling infiltrated flow has not been well developed. Hence, we determined affected by established model suitable MP‐contaminated soils. Quantitative findings indicated that saturated conductivity soil–MP mixture was 10.8%–50.0% smaller than pure soil, which decreased increased with increase in size, respectively. The always had significant influences conductivity; contrast, generated under condition small size. Besides, higher or MPs led weaker water‐holding capacity, residual content 0.6% – 41.5% 0.2% 11.6%, Furthermore, presence inhibited infiltration, wetting front migration rate cumulative infiltration 7.1% 29.4% 4.7% 21.7%, respectively, Correlation analysis negatively correlated saturated/residual moisture, infiltration; addition, conductivity, compared (15.63%), (46.28%) played major role response movement changes external environment.

Microplastics affect ecosystem multifunctionality: Increasing evidence from soil enzyme activities

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(15), P. 4379 - 4405

Published: July 22, 2024

Abstract Microplastics (MPs) as emerging contaminants have a global occurrence, including both terrestrial and marine ecosystems. Soil enzymes contribute to maintaining ecosystem multifunctionality, for example, nutrient cycling, organic material decomposition, carbon climate regulation. Our present review highlights the impacts of MPs on soil enzyme activities, influencing factors, underlying mechanisms. Increasing findings confirm that can change activities range involved in biogeochemical cycling C N. However, current results are highly controversial. The effects vary from significant nonsignificant dependent polymer type, biodegradability, dosage, size, shape, aging degree MPs, exposure conditions. Compared traditional biodegradable generally show more pronounced effects. via different pathways. On one hand, directly structure, leading alterations activity. other create unique habitats, provide sources specific functional microbes producing enzymes, release plastic additives pollutants disturbing production these enzymes. Furthermore, alter physicochemical biological properties, availability substrates, plants fauna, regulating their functions. In conclusion, regulate pose profound impact multifunctionality.
