The harmful effects of microplastics (MPs) pollution in the soil ecosystem have drawn global attention recent years. This paper critically reviews MPs on microbial diversity and functions relation to nutrients carbon cycling. Reports suggested that both plastisphere (MP-microbe consortium) MP-contaminated soils had distinct lower than non-contaminated soils. Alteration physicochemical properties interactions within facilitated enrichment plastic-degrading microorganisms, including those involved (C) nutrient conferred a significant increase relative abundance nitrogen (N)-fixing phosphorus (P)-solubilizing bacteria, while decreased nitrifiers ammonia oxidisers. Depending types, increased bioavailable N P contents nitrous oxide emission some instances. Furthermore, regulated functional activities owing combined toxicity organic inorganic contaminants derived from frequently encountered environment. However, thorough understanding among other still needs develop. Since currently available reports are mostly based short-term laboratory experiments, field investigations needed assess long-term impact (at environmentally relevant concentration) microorganisms their under different types agro-climatic conditions.

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.

Microplastic pollution promotes soil respiration: A global‐scale meta‐analysis

Global Change Biology, Год журнала: 2024, Номер 30(7)

Опубликована: Июль 1, 2024

Abstract Microplastic (MP) pollution likely affects global soil carbon (C) dynamics, yet it remains uncertain how and to what extent MP influences respiration. Here, we report on a meta‐analysis determine the effects of microbiome CO 2 emission. We found that significantly increased contents organic C (SOC) (21%) dissolved (DOC) (12%), activity fluorescein diacetate hydrolase (FDAse) (10%), microbial biomass (17%), but led decrease in diversity (3%). In particular, increases components further promote emission (25%) from soil, with much higher effect MPs these emissions than biomass. The could be attributed opposite vs. diversity, as accumulation recruited some functionally important bacteria provided additional substrates for specific heterotrophic microorganisms, while inhibiting growth autotrophic taxa (e.g., Chloroflexi , Cyanobacteria ). This study reveals can increase by causing shifts microbiome. These results underscore potential importance plastic terrestrial fluxes, thus climate feedbacks.

Risks Associated with the Presence of Polyvinyl Chloride in the Environment and Methods for Its Disposal and Utilization

Materials, Год журнала: 2023, Номер 17(1), С. 173 - 173

Опубликована: Дек. 28, 2023

Plastics have recently become an indispensable part of everyone's daily life due to their versatility, durability, light weight, and low production costs. The increasing use plastics poses great environmental problems incomplete utilization, a very long period biodegradation, negative impact on living organisms. Decomposing lead the formation microplastics, which accumulate in environment organisms, becoming food chain. contamination soils water with poly(vinyl chloride) (PVC) seriously threatens ecosystems around world. Their durability weight make microplastic particles easily transported through or air, ending up soil. Thus, problem pollution affects entire ecosystem. Since microplastics are commonly found both drinking bottled water, humans also exposed harmful effects. Because existing risks associated PVC ecosystem, intensive research is underway develop methods clean remove it from environment. plastic, especially microplastic, results reduction soil resources used for agricultural utility purposes. This review provides overview PVC's its disposal options.

Microplastics affect ecosystem multifunctionality: Increasing evidence from soil enzyme activities

Land Degradation and Development, Год журнала: 2024, Номер 35(15), С. 4379 - 4405

Опубликована: Июль 22, 2024

Abstract Microplastics (MPs) as emerging contaminants have a global occurrence, including both terrestrial and marine ecosystems. Soil enzymes contribute to maintaining ecosystem multifunctionality, for example, nutrient cycling, organic material decomposition, carbon climate regulation. Our present review highlights the impacts of MPs on soil enzyme activities, influencing factors, underlying mechanisms. Increasing findings confirm that can change activities range involved in biogeochemical cycling C N. However, current results are highly controversial. The effects vary from significant nonsignificant dependent polymer type, biodegradability, dosage, size, shape, aging degree MPs, exposure conditions. Compared traditional biodegradable generally show more pronounced effects. via different pathways. On one hand, directly structure, leading alterations activity. other create unique habitats, provide sources specific functional microbes producing enzymes, release plastic additives pollutants disturbing production these enzymes. Furthermore, alter physicochemical biological properties, availability substrates, plants fauna, regulating their functions. In conclusion, regulate pose profound impact multifunctionality.
