Microplastics (MPs) degradation due to light radiation, weathering, water erosion and biodegradation might change MPs physical chemical characteristics thereby behaviors in natural environments. This study conducted a comparison investigation on polyvinyl chloride (PVC), polyethylene (PE) polyamide (PA) three different environmental conditions, namely simulated UV light, body. The results showed that of environments is more complex than the case controlled experimental condition (such as light). In conditions body, are easily covered by sediments/microorganisms.

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

European Journal of Soil Science, Год журнала: 2025, Номер 76(1)

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 in soils: A comparative review on extraction, identification and quantification methods

Journal of Environmental Management, Год журнала: 2025, Номер 377, С. 124556 - 124556

Опубликована: Фев. 22, 2025

Microplastics (MPs) have been continuously accumulating in soil, posing significant environmental concerns due to their potential toxicity and role as pollutant vectors. Effective monitoring of MPs soils requires appropriate methods for extraction, identification quantification. This comparative review systematically examined various used MP analysis from solid matrix environments, highlighting the advantages disadvantages each technique. Soils are heterogeneous complex matrices, which can interact differently with MPs, rendering separation a challenge. Key challenges include interactions between soil organic matter detection limitations smaller size interfere accurate extraction. Specialized techniques devices required precise Digestion be effective removing matter, although harsh digestion degrade MPs. To improve liability analysis, it is critical minimize steps that may reduce accuracy such filtration, inappropriate sample size. Conversely, adjusting or combining enhance precision analysis. offers forward-looking perspective by advocating extraction approaches, thus providing more accurate, reproducible holistic framework soils. These insights anticipated guide future research promote standardized protocols efforts.
