The impact on the hydrologic cycle of permafrost degradation under the influence of climate change has caused an inestimable threat to sustainable regulation of the ecosystem. This study quantified the responses of main hydrological elements, including soil moisture, groundwater, runoff components and discharge to totally degraded permafrost in eastern High Asia by establishing cases with and without thermodynamics using a cold region model combining hydrological processes and thermodynamics.…

Direct discharge of untreated industrial waste water in water bodies and then irrigation from these sources has increased trace metals contamination in paddy fields of southern China. Among trace metals, cadmium (Cd) and lead (Pb) are classified as most harmful contaminants in farmland to many organisms including plants, animals and humans. Rice is a staple food which is consumed by half population of the world; due to longer growth period it can easily absorb and accumulate the trace metals …

Biochar has attracted wide interest due to its important role in the synthesis of functionalized carbon materials. Molten alkali carbonates (MC) pyrolysis as a novel mean was explored to obtain superior bamboo biochar compared with alkali impregnation pretreating bamboo powder associated with pyrolysis. The properties of biochar produced by MC pyrolysis were enhanced, suggesting an increase in BET surface area of 43.59 m/g compared with non-pretreat biochar of 5.76 m/g, and possessed preferab…

Catalytic elimination of chlorinated volatile organic compounds (CVOCs) from the industrial sources of emission usually confronted with catalyst deactivation and secondary pollution. As a widely used catalyst in selective catalytic reduction (SCR) of nitric oxides, VO-WO/TiO catalysts (denoted as VWT) have been also applied for eliminating the CVOCs, especially those from the municipal solid waste (MSW) incineration. However, the effect of heavy metals on the reaction characteristics of this …

This study developed a novel calcium-based magnetic biochar by pyrolysing rice straw mixed with calcium carbonate and iron oxide for stabilization of contamination of multiple metals. A 160-day incubation study was conducted to investigate its performance in stabilization of cadmium and arsenic co-contamination in soil. Both biochar and Ca-MBC treatments increased soil pH, decreased the bioavailability of cadmium. Ca-MBC decreased but biochar enhanced the bioavailability of arsenic. The BCR (…

A series of Fe doped LaMnO catalysts were prepared to control the production of byproducts such as O, NO, and CO, during the degradation of volatile organic compounds with a non-thermal plasma. Eliminating these potentially toxic byproducts will make non-thermal plasma technologies applicable for a wider range of commercial applications. The modified LaMnO catalysts are combined in NTP-catalysis reactor with optimal configuration. Experimental results show that doping Fe on LaMnO catalysts ca…

Detection and characterization of interactions between crop plants and hydrogen peroxide (HO) is significant for the exploration of the mechanisms in plant pathology. The objective of this research is to estimate spectral characteristics of rapeseed leaves (Brassica napus L.) during treatment with different HO concentrations (0, 0.5, 1.0, and 3.0 mmol/L) by using Raman spectroscopy (RS) (800-1800 cm) and hyperspectral imaging (HSI) (400-1000 nm). Cluster analysis of RS and HSI data between th…

The effects of an on-site biomass (rice straw) equivalent biochar-returning strategy (RSC) on rice yield, soil nutrients and bacterial community composition were examined in a four-year field trial (2013-2016) conducted in a paddy field in south China. Three treatments were set up including annual on-site biomass return (RS, rice straw at 8 t ha yr), annual on-site biomass equivalent biochar-return (RSC, rice straw biochar at 2.8 t ha yr with a 35 % carbonization rate) and control (CK, no ric…

Composite beads are packed in the anode chamber of a microbial fuel cell (MFC), providing more area for microbial attachment and growth, increasing the efficiency of removal of toluene from toluene-contaminated groundwater. The composite beads were fabricated by integrating carbon coke (CC) with a relatively large specific surface area to which microorganisms easily adhere with conductive carbon black (CCB), which has low electrical resistance. Since the advantages of both are complementary, …

The present study was to investigate the molecular mechanism underlying lymphocyte activation by total polysaccharides from Atractylodis macrocephalae (RAMPtp). The results showed that RAMPtp significantly promoted the secretions of cytokines (IFN-γ, IL-1α, IL-21, IFN-α, CCL4, CXCL9 and CXCL10), increased the proportions of CD4 and CD8 subpopulations, and enhanced the expressions of c-JUN, NFAT4, STAT1 and STAT3. microRNA sequencing identified 67 differentially expressed miRNAs (DEMs) in RAMP…
