Although the presence of nanoplastics in aquatic and terrestrial ecosystems has received increasing attention, little is known about its potential effect on ecosystem processes functions. Here, we evaluated if differentially charged polystyrene (PS) (PS-NH2 PS-SO3 H) exhibit distinct influences microbial community structure, nitrogen removal (denitrification anammox), emissions greenhouse gases (CO2 , CH4 N2 O), multifunctionality soils with without earthworms through a 42-day microcosm experiment. Our results indicated that significantly altered soil structure functions, more pronounced effects for positively PS-NH2 than negatively H. Ecologically relevant concentration (3 g kg-1 ) inhibited both denitrification anammox rates, while environmentally realistic (0.3 decreased rate enhanced rate. The O flux was always 6%-51% by types nanoplastics, whereas CO2 were most cases. Significantly, although global warming total increased 21%-75% earthworms. Moreover, 4%-12% 0.3 but 4%-11% 3 nanoplastics. findings provide only evidence to date rapid increase altering not also multifunctionality, it may emission their some extent.

Nanoplastics in the soil environment: Analytical methods, occurrence, fate and ecological implications

Soils play a very important role in ecosystems sustainability, either natural or agricultural ones, serving as an essential support for living organisms of different kinds. However, the current context extremely high plastic pollution, soils are highly threatened. Plastics can change chemical and physical properties may also affect biota. Of particular importance is fact that plastics be fragmented into microplastics and, to final extent nanoplastics. Due their low size surface area, nanoplastics even have higher impact soil ecosystems. Their transport through edaphic environment regulated by physicochemical particles themselves, anthropic activities biota interactions. degradation associated with series mechanical, photo-, thermo-, bio-mediated transformations eventually conducive mineralisation. tiny precisely main setback when it comes sampling subsequent processes identification quantification, albeit pyrolysis coupled gas chromatography-mass spectrometry other spectroscopic techniques proven useful analysis.

Thus, given omnipresence seriousness menace, this review article pretends provide general overview most recent data available regarding determination, occurrence, fate effects soils, special emphasis on ecological implications.

Nanoplastics (NPs) are increasingly perceived as an emerging threat to terrestrial environments, but the adverse impacts of NPs on soil fauna and mechanisms behind these negative outcomes remain elusive. Here, a risk assessment was conducted model organism (earthworm) from tissue cell. Using palladium-doped polystyrene NPs, we quantitatively measured nanoplastic accumulation in earthworm investigated its toxic effects by combining physiological with RNA-Seq transcriptomic analyses. After 42-day exposure, accumulated up 15.9 143.3 mg kg-1 for low (0.3 kg-1) high (3 dose groups, respectively. retention led decrease antioxidant enzyme activity reactive oxygen species (O2- H2O2), which reduced growth rate 21.3 %-50.8 % caused pathological abnormalities. These were enhanced positively charged NPs. Furthermore, observed that irrespective surface charge, after 2 h gradually internalized coelomocytes (∼0.12 μg per cell) mainly amassed at lysosomes. Those agglomerations stimulated lysosomal membranes lose stability even rupture, resulting impeded autophagy process cellular clearance, eventually coelomocyte death. In comparison negatively nanoplastics, exerted 83 higher cytotoxicity. Our findings provide better understanding how posed harmful have important implications evaluating ecological

The forgotten impacts of plastic contamination on terrestrial micro- and mesofauna: A call for research

Environmental Research, Год журнала: 2023, Номер 231, С. 116227 - 116227

Опубликована: Май 25, 2023

Microplastics (MP) and nanoplastics (NP) contamination of the terrestrial environment is a growing concern worldwide thought to impact soil biota, particularly micro mesofauna community, by various processes that may contribute global change in systems. Soils act as long-term sink for MP, accumulating these contaminants increasing their adverse impacts on ecosystems. Consequently, whole ecosystem impacted microplastic pollution, which also threatens human health potential transfer food web. In general, ingestion MP different concentrations can adversely affect development reproduction, impacting moves horizontally vertically because movement organisms disturbance caused plants. However, effects micro-and are largely overlooked. Here, we give most recent information forgotten microfauna communities (protists, tardigrades, rotifers, nematodes, collembola mites). More than 50 studies focused between 1990 2022 have been reviewed. plastic pollution does not directly survival organisms, except under co-contaminated plastics increase (e.g. tire-tread particles springtails). Besides, they at oxidative stress reduced reproduction potworms, springtails or It was observed could passive transporters, shown mites. Finally, this review discusses how micro- play key role facilitating (bio-)degradation NP through systems and, therefore, depths. research should be mixtures, community level experiments.

Soil ecosystems are under considerable pressure due to anthropogenic factors, including microplastics (MPs) pollution and drought. However, little is known about the interactive effects of MPs drought on soil organisms, especially micro-food web. We conducted a microcosm experiment with (including two types sizes MPs) investigate their interaction microbial, protist, nematode communities in found that significantly decreased complexity stability web, greater negative biodegradable smaller-sized than conventional larger-sized MPs. Drought had web non-MPs soils while increasing soils. increased proportion correlations between bacteria fungi decreasing protists nematodes Our study reveals may alleviate by reducing competition among lower trophic levels higher

Microplastics (MPs) can act as carriers for environmental pollutants; therefore, MPs combined with heavy metal pollution are attracting increasing attention from researchers. In this study, the potential of plant growth-promoting bacterium Bacillus sp. SL-413 to mitigate stress caused by exposure both and cadmium (Cd) in sorghum plants was investigated. The effects inoculation on biomass were investigated using hydroponic experiments, evaluation Cd accumulation enzyme activity changes transcriptomics approaches used analyze its effect gene expression. results showed that polyethylene (PE) reduced length fresh dry weights thus exerted a synergistic toxic effect. However, strains alleviated significantly increased biomass. Inoculation aboveground belowground parts 11.5-44.6% 14.9-38.4%, respectively. Plant physiological measurements indicated reactive oxygen species (ROS) content 10.5-27.2% thereby oxidative stress. Transcriptome sequencing Cd+MP contamination induced downregulation expression, particularly genes related amino sugar nucleotide metabolism, starch sucrose hormone signal transduction, sorghum. resulted an increase proportion upregulated involved antioxidant defense, cell wall biology, other metabolic pathways, which included phenylpropanoid biosynthesis, photosynthesis, flavonoid MAPK signaling pathways. upregulation these promoted tolerance under conditions. This study provides first demonstration bacteria alleviate regulating These findings provide reference plant-microbial remediation Cd.
