Aeration is an important factor to regulate composting efficiency and nitrogen loss. This study aimed compare the effects of different aeration modes (continuous intermittent) rate on conversion bacterial community in from dehydrated sludge corn straw. Results showed that intermittent mode at same volume was superior continuous terms NH 3 emission reduction, germination index (GI) improvement. Intermittent with 1200 L/h (aeration 5 min, stop 15 min) [K5T15 (V1200)] 300 helped conservation fractions accelerate process. However, it most advantageous use 150 reduce ensure effective The K5T15 (V1200) fastest temperature rise, longer duration thermophilic stage highest GI (95%) composting. cumulative higher than mode. V300 23.1% lower (V1200). dominant phyla straw were Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes. phylum Firmicutes (49.39%~63.13%), genus Thermobifida (18.62%~30.16%). relative abundance greater (63.13%) (57.62%), Pseudomonas lowest emission. suggested adjustment could affect core bacteria loss

Freshwater wetlands are the wetland ecosystems surrounded by freshwater, which at interface of terrestrial and freshwater ecosystems, rich in ecological composition function. Biodiversity plays a key role maintaining stability their habitat functions. Due to anthropogenic interference global change, biodiversity decreases, turn destroys function leads serious degradation wetlands. An in-depth understanding effects on its regulation is crucial for conservation. Therefore, this paper reviews environmental drivers wetlands, explores plant diversity microbial stability, reveals impacts mechanisms changes biodiversity, further proposes an outlook research. This provides important reference conservation enhancement.

The complexity of crude oil composition, combined with the fluctuating oxygen level in contaminated environments, poses challenges for bioremediation pollutants, because compound-specific microbial degradation petroleum hydrocarbons under certain conditions. As a result, facultative bacteria capable breaking down both aerobic and anaerobic conditions are presumably effective, however, this hypothesis has not been directly tested. In current investigation,

Abstract The confined groundwater of arid sedimentary plains has been disturbed by long‐term anthropogenic extraction, and its hydrochemical quality is required for sustainable development. present research investigates the characteristics, formation, potential health threats, suitability in central North China Plain. Results show that a slightly alkaline nature study area, predominantly dominated fresh‐soft Cl‐Na HCO 3 ‐Na types. Water chemistry governed water–rock interactions, including dissolution evaporites cation exchange. Approximately 97% sampled groundwaters exceed prescribed standard F − . It mainly due to geological factors such as mineral dissolution, exchange, competitive adsorption may also be released from compacted soils because extraction. Enriched can pose an intermediate higher non‐carcinogenic risk more than 90% population. poses greatest threat population north‐eastern part especially infants children. For development, use irrigation area should avoided, attention paid soil salinization infiltration risks. In are found excellent or good domestic purposes based on Entropy‐weighted Quality Index. However, caused high contents cannot ignored. Therefore, it recommended differential water supplies implemented according spatial heterogeneity ensure scientific rational resources. Practitioner Points hydrochemistry plain extraction was investigated. multiple drinking were evaluated. characteristics formation mechanism under influence revealed.

Abstract In South China, karst groundwater is an important water resource for industrial, agricultural, and drinking purposes. However, aquifers are highly vulnerable to pollution, leading deteriorating quality posing potential health risks local residents. this study, 22 samples were collected from a aquifer in the southwestern part of Hubei Province. The hydrogeochemical characteristics their controlling factors examined, associated with pollutant concentrations assessed. results showed that slightly alkaline low chemical oxygen demand values, indicating good quality. facies type was identified as HCO 3 ‐Ca at most sample spots, showing total dissolved solids concentrations. Substantial spatial variations Na + , CO 2− NO 2 − found, whereas K Ca 2+ Cl F small. addition, dissolution gypsum deposits magnesium carbonate sedimentary rocks sampling sites resulted types •SO 4 ‐Ca•Mg, chemistry study area mainly controlled by water–rock interactions, well specific sites. affected atmospheric precipitation. derived precipitation, domestic sewage, septic tanks, industrial activities, SO sulfate rock dissolution, sulfide mineral oxidation. These highlight absence human infants, children, adults, below corresponding regional background values. contrast, cannot be ignored, particularly infants. This offers scientific guidelines protecting allocating resources.

The makeup of soil microbial communities may serve as a crucial predictor the alpine grassland ecosystem. Climate change and human disturbance have resulted in intensified ecosystem degradation, such rocky desertification, which modify structures composition microorganisms. However, little is known about effects desertification on soil. Here, we investigated five different layers Qinghai-Tibet Plateau, including nil rock (NRD); potential (PRD); light (LRD); moderate (MRD); severe (SRD), compared bacterial community with physiochemical properties conditions. result showed that significantly altered but did not affect abundance diversity. At same time increased, organic carbon (SOC), total nitrogen (TN), alkali hydrolyzable (AN), available phosphorus (AP), potassium (AK) decreased significantly, while pH, (TP); (TK) increased. Redundancy analysis revealed AK, TP, SOC are key factors influencing communities. Our finding provides basic information scientific reference for restoration grasslands.
