Deposition of potentially toxic elements (PTEs) in soils due to different types mining activities has been an increasingly important concern worldwide. Quantitative differences soil PTEs contamination and related health risk among typical mines remain unclear. Herein, data from 110 coal 168 metal across China were analyzed based on 265 published literatures evaluate pollution characteristics, spatial distribution, probabilistic risks PTEs. The results showed that PTE levels both mine significantly exceeded background values. geoaccumulation index (I

Soil is a complex and dynamic ecosystem containing diverse array of microorganisms, plays crucial multifaceted role in various functions the ecosystem. Substantial fluctuations environmental conditions arise from global changes. The microbial shifts soil concordance with changing factors, or combination these are high significance. Exploring contribution change drivers to community improve predictions response functioning prime importance. Promoting health microorganisms maintains overall fertility soil, which turn supports terrestrial ecosystems agricultural systems. current review aims assemble different abiotic factors stressors that exist environment affect community. More focus will be given one stressors—antibiotics, recent emerging pollutant. effects on future due presence antibiotics addressed. scope interaction other pollutants like plastics heavy metals (HMs) examined.

Soil fungi play a critical role in the biogeochemical cycles of forest ecosystems. Larix gmelinii is strong and important timber tree species, which forms close associations with wide range soil fungi. However, temporal-spatial disparity effects on assembly fungal communities L. forests are poorly understood. To address these questions, total 120 samples, including 60 bulk root were collected from Aershan Genhe July (summer) October (autumn)2021. We obtained 7,788 operational taxonomic units (OTUs) after merging, filtering, rarefying using high-throughput sequencing. The dominant phyla Basidiomycota, Ascomycota, Mortierellomycota, Mucoromycota. There 13 families, among families average relative abundance more than 5% included Thelephoraceae, Mortierellaceae, Archaeorhizomycoaceae, Inocybaceae. In functional guilds, symbiotrophic had advantage identified functions, abundances pathotrophic saprotrophic varied significantly between sites. 12 differentially expressed across compartments, 10 seasons, 69 variation alpha diversity was greater that rhizosphere soil. Among three parts (compartment, season, site), site crucial effect beta community. Deterministic processes dominated community Genhe, whereas stochastic Aershan. physicochemical properties climatic factors affected structure, nitrogen pH greatest effect. This study highlights spatial variations vital structure forests, great significance for us maintaining health forests.

Elevation is one of the most influential factors affecting soil characteristics and microbial communities in forest ecosystems. Nevertheless, there no consensus on how characteristics, microbials, their relationships response to elevation mountain ecosystem. We investigated physicochemical activity enzymes, community at elevational sites from 600 2400 m above sea level (asl) western slopes Fanjing Mountain ecosystem, China. The were determined by high throughput 16S rRNA ITS amplicon sequencing. results demonstrated that total nitrogen (TN) showed a slight decrease, whereas phosphorus (TP) potassium (TK) gradually tended increase with increasing elevation. large macroaggregates (>2 mm) accounted for largest proportion aggregate fraction (66.23%–76.13%) 0–10 cm layer average values electrical conductivity (EC), organic carbon (SOC), cation exchange capacity (CEC) concentration 0–60 undulated elevation, highest observed 1500–1800 asl 1800–2100 asl, respectively. activities urease, sucrase, acid phosphatase, catalase clearly differed (p < 0.05) minimum found 2100–2400 asl. Interesting, depth, these indicating surface aggregation. In addition, (bacterial fungal) diversity exhibited single-peak pattern Our also revealed bacterial fungal varied significantly different sites. dominated phyla Acidobacteria, Pseudomonadota, Chloroflexi, Basidiomycota Ascomycota communities. Pearson redundancy analyses SOC, TP, four aggregates significant influencing community. conclusion, properties enzyme jointly explained Mountain. this study provide insights into influence communities,
