Key Role of Vegetation Cover in Alleviating Microplastic-Enhanced Carbon Emissions

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 6, 2024

Microplastics (MPs) are considered to influence fundamental biogeochemical processes, but the effects of plant residue-MP interactions on soil carbon turnover in urban greenspaces virtually unknown. Here, an 84-day incubation experiment was constructed using four types single-vegetation-covered soils (6 years), showing that polystyrene MP (PSMP) pollution caused unexpectedly large increase CO2 emissions. The additional originating from highly bioavailable active dissolved organic matter molecules (<380 °C, predominantly polysaccharides) converted persistent (380–650 aromatic compounds) rather than PSMP derivatives. However, priming effect derivatives weakened plant-driven (resistivity: shrub > tree grass). This can be explained two perspectives: (1) Plant residue-driven humification processes reduced percentage derived PSMPs. (2) residues accelerated bacterial community succession (dominated by residue types) slowed fungal demise (retained turnover-related functional taxa), enabling specific enrichment glycolysis, citric acid cycle and pentose phosphate pathway. These results provide a necessary theoretical basis understand role reducing harm at ecological level refresh knowledge about importance biodiversity for ecosystem stability.

Variability in Microbial Communities Driven by Particulate Matter on Human Facial Skin

Toxics, Journal Year: 2024, Volume and Issue: 12(7), P. 497 - 497

Published: July 8, 2024

Microbial communities are known to play an important role in maintaining ecological balance and can be used as indicator for assessing environmental pollution. Numerous studies have revealed that air pollution alter the structure of microbial communities, which may increase health risks. Nevertheless, relationships between particulate matter (PM) caused by terms risk assessment not well understood. This study aimed validate influences PM chemical compositions on assess associated Our results, based similarity analysis, stability had a greater than 73%. In addition, altered richness diversity were significantly with compositions. Volatile organic compounds (VOCs) polycyclic aromatic hydrocarbons (PAHs) exerted positive influence different variables. Additionally, stronger linear correlation was observed hydroxyl radicals (·OH) communities. All estimated risks from compositions, calculated under variables, exceeded acceptable level factor more 49. Cr 1,2-Dibromoethane displayed dual adverse effects non-carcinogenic carcinogenic Overall, provides insights into fundamental mechanisms variability driven PM, support crucial microorganisms atmospheric environment.

A Comprehensive Review of Hydrocarbon Contaminated Soil Behavior, Geotechnical Properties and Potential Remediation

Soil and Sediment Contamination An International Journal, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 45

Published: Aug. 27, 2024

Soil contamination due to urban and industrial activities has caused significant land degradation changes in the geotechnical properties of soils. Among many contaminants, hydrocarbons pose severe threats not only from an engineering point view but are also hazardous environment. This review article critically analyzes essential aspects different hydrocarbon types as a source various soil their implications design. The modifications require in-depth investigation, especially at micro-scale, by assessing particle interaction with hydrocarbons. compounds possess ability alter morphological characteristics particles, which, turn, influences shear mobilization Furthermore, several remediation techniques, such biological, chemical, physical, or thermal treatment methods, available solidify, remove immobilize However, limitations exist applicability some techniques. Taking these considerations into account, primary purpose this paper is create consensus about how interact soils, what triggers interactions, which mostly affected, techniques will be more effective, quickly method can applied.
