Microplastics (MPs) are small plastic pieces less than 5 mm in size. Previous studies have focused on the sources, transports, and fates of MPs marine or sediment environments. However, limited attention has been given to role land as primary source MPs, how polymers transformed into through biological abiotic effects during transport process remains unclear. Here, we focus exploration main sources soil, highlighting that MP generation is not solely a byproduct production but can also result from impact factors transport. This review presents new perspective understanding degradation considering soil distinct fluid suggesting transformation change mediated by occur surface, while biodegradation occurs interior. viewpoint suggested because some becomes obvious interior, whose surface expected colonize microorganisms, gradually considered carbon independent photosynthesis net production. emphasizes need understand basic information for rational evaluation its environmental toxicity. Such enables better control pollution affected areas prevents contamination unaffected regions. Finally, knowledge gaps future research directions necessary advancements this field provided.

Sub-micron microplastics affect nitrogen cycling by altering microbial abundance and activities in a soil-legume system

Journal of Hazardous Materials, Год журнала: 2023, Номер 460, С. 132504 - 132504

Recently, the environmental and agricultural impact of plastic waste has attracted considerable attention. Here, we investigated sub-micron polyethylene (PE) polypropylene (PP) microplastics (MPs) on nitrogen cycling, with emphasis bacterial abundance diversity in a soil-soybean (Glycine max) system. Exposure to soil containing MPs (50 500 mg kg-1) did not affect soybean growth, but significantly increased plant uptake, which was confirmed by activities nitrogenase glutamine synthetase root. Additionally, there an increase 16S gene copy number carbon substrate utilization, indicating activity rhizosphere microbial communities. Moreover, MP contamination affected taxonomic profile bacteria, especially symbiotic free-living bacteria involved cycling. Furthermore, qPCR analysis nitrogen-related genes Kyoto Encyclopedia Genes Genomes rRNA sequencing data revealed functional associated fixation nitrification. However, concentration polymer type have significant our Overall, these results provide insights into interactions between communities soil-legume

Mineralisation and priming effects of a biodegradable plastic mulch film in soils: Influence of soil type, temperature and plastic particle size

Soil Biology and Biochemistry, Год журнала: 2023, Номер 189, С. 109257 - 109257

There is increasing use of biodegradable mulch films (BDMs) as an environmentally sustainable alternative to traditional in agriculture. However, their degradation fate and priming effect (PE) on native soil organic matter (SOM), including the form microplastics (MPs) after disintegration, are not well known. In this study, we investigated mineralisation a BDM (0–2000 μm MPs) its PEs three soils, i.e., Ferralsol, Vertisol Solonetz. The MPs were incubated at concentration 0.8% (w/w) separately soils temperatures 20, 30 40 °C for 150 days. We also evaluated MP particle size two (a Ferralsol Vertisol). Six fractions (i.e., <100, 100–250, 250–500, 500–1000, 1000–2000, 2000–4750 μm) A δ13C technique was employed determine proportion C mineralised from SOM owing distinct values. Temperature, type, interactions all key factors PEs. increased with 20 over time few exceptions. At °C, greater carbon clay content showed than Opposite trends observed °C. both exhibited similar suggesting that 'co-metabolism' may be dominant high temperatures. Furthermore, smaller tended induce mineralisation, whereas larger caused small particles.
