Microplastics (MPs), miniscule plastic particles measuring less than 5 mm in size, have become a concern terrestrial ecosystems, with primarily agricultural and wetland soils being the highest loadings. The adverse effect of MPs might lead to changes physicochemical biological characteristics soil including properties, microbial communities, plants, as well potential or affirmed correlations among them. Therefore, understanding risks effects MPs, particularly within soil-plant-microbe context is challenging subject substantial scientific inquiry. This comprehensive review focused on rhizosphere plant-microbe symbiotic relationships, implications for plant growth ecosystem-level nutrient fluxes. alter community composition, enzymatic activities rhizosphere, influencing availability uptake by plants. These can disrupt interactions, such mycorrhizal associations nitrogen-fixing symbioses, ultimately impacting cycling nutrients ecosystems. Furthermore, we elaborate relationships carrying Future research directions solutions microplastics menace acknowledging combined other contaminants, advanced technologies identification quantification, engineering remediation. knowledge MPs-induced impacts interactions essential generate mitigating actions environmental management conservation.

The accumulation of microplastics in agricultural soil brings unexpected adverse effects on crop growth and quality, which is threatening the sustainability agriculture. Biochar an emerging amendment material interest as it can remediate pollutants. However, mechanisms underlying biochar alleviated toxic crops were largely unknown. Using a common economic crop, peanut targeted species, present study evaluated plant physiologica molecular response rhizosphere microbiome when facing microplastic contamination amendment. Transcriptome analyses conducted root treated with CK (no no addition), MP (1.5% polystyrene addition) MB microplastic+2% shell addition). results indicated that had inhibitory development bacterial diversity function. application could significantly promote expressions key genes associated antioxidant activities, lignin synthesis, nitrogen transport energy metabolism to alleviate reactive oxygen species stress, structure damage, nutrient limitation, inhibition induced by root. In addition, showed restore richness microbial communities inhibited availability regulating abundance cycling-related organic matter decomposition-related communities. Consequently, enhance promoting oxidative stress resistance, benefit microecological environment for development, thereby improved plant-soil system health microplastic-contaminated agroecosystem.

Microplastics in Agricultural Systems: Analytical Methodologies and Effects on Soil Quality and Crop Yield

Agriculture, Journal Year: 2022, Volume and Issue: 12(8), P. 1162 - 1162

Published: Aug. 5, 2022

Around one million metric ton of plastics is produced worldwide daily. Plastic contamination aggravated when the particles reach sizes between 5 mm and 1 μm, giving rise to microplastics, which are omnipresent in environment, especially agroecosystems. To appreciate magnitude this problem, review analyzes 177 scientific works focus on occurrence effects microplastics agricultural soils. Firstly, sources, behavior fate agroecosystems evaluated. Then, absence a standard methodology for study farmland soils, procedures have been employed microplastic separation (density floatation 73% discussed works), identification quantification (stereomicroscopy, 77%; infrared analysis, 62%) addressed provide practical work guideline. Finally, we highlight interaction soil microbiota, fauna vegetation (negative reported 83% cases), including crop production (decrease growth parameters 63% reports). From review, it can be inferred that may disrupt biophysical environment soil, potentially leading economic losses their entrance into trophic food chain, affecting human feeding health.

Plastics have revolutionised human industries, thanks to their versatility and durability. However, extensive use, coupled with inadequate waste disposal, has resulted in plastic becoming ubiquitous every environmental compartment, posing potential risks the economy, health environment. Additionally, under natural conditions, breaks down into microplastics (MPs<5 mm). The increasing quantity of MPs exerts a significant burden on soil environment, particularly agroecosystems, presenting new stressor for soil-dwelling organisms. In this review, we delve effects MP pollution ecosystems, specific attention (a) transport soils, (b) changes (c) interaction physical, chemical biological components soil. We aim shed light alterations distribution, activity, physiology growth flora, fauna microorganisms response MPs, offering an ecotoxicological perspective risk assessment plastics. are strongly influenced by intrinsic traits, including polymer type, shape, size abundance.

Microplastics (MPs) are emerging pollutants whose occurrence is a global problem in natural ecosystems including soil. Among MPs, polyvinyl chloride (PVC) well-known polymer with remarkable resistance to degradation, and because its recalcitrant nature serious environmental concerns created during manufacturing waste disposal. The effect of PVC (0.021% w/w) on chemical microbial parameters an agricultural soil was tested by microcosm experiment at different incubation times (from 3 360 days). parameters, CO2 emission, fluorescein diacetate (FDA) activity, total organic C (TOC), N, water extractable (WEOC), N (WEN) SUVA254 were considered, while the structure communities studied taxonomic levels (phylum genus) sequencing bacterial 16S fungal ITS2 rDNA (Illumina MiSeq). Although some fluctuations found, microbiological exhibited significant trends. Significant (p < 0.05) variations FDA hydrolysis, TOC, WEOC WEN found PVC-treated soils over times. Considering communities, presence significantly affected abundances specific taxa: Candidatus_Saccharibacteria, Proteobacteria, Actinobacteria, Acidobacteria Bacteroides among bacteria, Basidiomycota, Mortierellomycota Ascomycota fungi. After one year experiment, reduction number dimensions detected supposing possible role microorganisms degradation. abundance both taxa phylum genus level also PVC, suggesting that impact this could be taxa-dependent.
