Characterization of the Differences in Dissolved Organic Matter (DOM) Adsorbed on Five Kinds of Microplastics Using Multiple Methods

Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1586 - 1586

Published: April 2, 2025

Microplastics (MPs) are ubiquitous in aquatic environments, soils, and beach sediments, demonstrating a remarkable ability to adsorb dissolved organic matter (DOM). Although there methods for extracting DOM from water, the approaches directly microplastics have not been thoroughly investigated, characterization of adsorbed on is also insufficient. In this study, five different types microplastic samples were collected each environmental media (water sediment), finally 25 obtained. This paper comparatively assessed extraction efficiency MPs with various solvents by using total carbon (TOC), culminating development sodium pyrophosphate-NaOH solution method optimized DOM. The morphology, material medium three primary factors affecting adsorption microplastics, highest enrichment ratio 1.4–1.8 times extruded polyethylene (EPE-MPs) characterized their porous structure flowing water environment. molecular weight showed multi-modal distribution pattern great dissimilarities among media. Gel permeation chromatography (GPC) indicated that weight-average (Mw) was 2750–4552 Da river MPs, 2760–5402 Qiantang River 1233–5228 East China Sea 440–7302 soil sediment 438–6178 respectively. Excitation-emission matrix-parallel factor analysis (EEM-PARAFAC) identified tyrosine-like substances high excitation region IV low I predominantly followed tryptophan-like II protein-like IV, while humic- fulvic-like regions V III, respectively, exhibited least affinity. findings underscored critical need comprehensively consider interactions between impacts pollution control strategies.

Effect of microplastics used in agronomic practices on agricultural soil properties and plant functions: Potential contribution to the circular economy of rural areas

Waste Management & Research The Journal for a Sustainable Circular Economy, Journal Year: 2024, Volume and Issue: 42(8), P. 634 - 650

Published: March 22, 2024

The extensive use of plastic materials and their improper disposal results in high amounts waste the environment. Aging plastics leads to breakdown into smaller particles, such as microplastics (MPs) nanoplastics. This research investigates used agricultural practices they contribute MP pollution soils. distribution characteristics MPs soils were evaluated.

Agricultural plastic pollution reduces soil function even under best management practices

PNAS Nexus, Journal Year: 2024, Volume and Issue: 3(10)

Published: Oct. 1, 2024

Abstract Soil plastic contamination is considered a threat to environmental health and food security. Plastic films—which are widely used as soil mulches—are the largest single source of agricultural pollution. Growing evidence indicates that high concentrations negatively affect critical functions. However, relationships between accumulation its biogeochemical consequences in regions with relatively low levels pollution remain poorly characterized. We sampled farms across California Central Coast (a region global importance extensive mulch-based production) assess degree fields subject “best practice” mulching application removal practices over multiple years. All exhibited surface contamination, macroplastic positively correlated microplastic levels, was moisture, microbial activity, available phosphate, carbon pool size. These effects occurred at less than 10% reported degrade field soils, but were subtle, no detectable relationship concentration. Identifying declines quality fragment suggests we must improve best management plasticulture limit productivity unabated accumulation.
