Summary: Endogenous hydrogen (H2) is produced through rhizobium-legume associations and can influence the microbial ecology and biogeochemistry of contaminated soils. This study shows that endogenous H2 promotes the biodegradation of tetrachlorobiphenyl PCB 77 by selecting bacteria harboring PCB degradation genes.

Summary: Endophytic bacteria Bacillus subtilis N-1 can effectively degrade toxic phthalate, and their colonization and function in soil-crop system have been investigated. The inoculated strain N-1-gfp can colonize in soil and rice plant, resulting in a shift in indigenous bacterial community and increased pollutant degradation. Furthermore, strain N-1-gfp displayed strong interaction with indigenous bacteria for accelerating phthalate degradation, reducing phthalate accumulation in plants, and promoting plant growth.

Summary: Intercropping of hyperaccumulator Sedum alfredii and oilseed rape significantly increased biomass, seed yield, and Cd accumulation in oilseed rape compared to monoculture, with Cd accumulation varying in different soil types. The study also showed that intercropping enhanced Cd phytoextraction potential and benefits evaluation index, providing a technical approach for phytoremediation practices and theoretical references for Cd phytoextraction and benefits evaluation development.

Summary: This study investigated the microbial diversity from the three domains of life in a long-term contaminated brownfield. The results showed a significant increase in microbial abundance according to PCB concentrations in soil samples. Some bacteria belonging to the Gammaproteobacteria class and fungi affiliated with the Saccharomycetes class or Pleurotaceae family, known for their ability to transform PCBs, were abundantly found in highly polluted soil samples.

Summary: In this study, we found that bioaugmentation with aerobic, polychlorinated biphenyl (PCB) degrading microorganisms can effectively reduce PCB emissions from contaminated sediment to air. Through synthetic samples and qPCR analysis, it was observed that the total PCB mass in the bioaugmented treatment decreased by 57% on average, with a preferential biodegradation of lower-chlorinated PCBs. The use of the phytogenic biosurfactant, saponin, was also found to enhance the abundance of the degrading microorganisms and promote the biodegradation process. These findings demonstrate that bioaugmentation can be an effective approach to reduce PCB emissions and minimize exposure risks in surrounding communities.

Summary: This study investigated the effect of photo-aged polystyrene microplastics (MPs) on microbial dechlorination of polychlorinated biphenyls (PCBs). The results showed that photo-aging increased the proportion of oxygen-containing groups in MPs and enhanced their inhibitory effect on microbial reductive dechlorination of PCBs. Furthermore, MPs altered the microbial community structure and interactions, leading to increased competition among bacteria. This study provides theoretical guidance for the in situ application of PCB bioremediation technology in the presence of MPs.

Summary: Biochar is gaining importance for remediation applications due to its attractive removal properties. Studies show that modified biochar can effectively remove antibiotics, polycyclic aromatic hydrocarbons (PAHs), and pesticides. The addition of inducer compounds and metal modifications further enhance the degradation capabilities of biochar. The interaction with microorganisms not only improves bioremediation levels but also offers better environmental and socio-economic prospects.

Summary: Intercropping hyperaccumulators with crops is a promising method for remediating arsenic-contaminated soil. The response of intercropping hyperaccumulators with legume plants to different gradients of As-contaminated soil was studied. Results showed that soil As concentration significantly influenced the As uptake by plants. Intercropping Pteris vittata with Sesbania cannabina increased As accumulation, while intercropping with Cassia tora decreased it. The As concentrations in the seeds of both legume plants met the national food standards.

Summary: Intercropping with hyperaccumulators and using engineered biochar are effective methods for remediating contaminated soil without affecting crop production. In this study, a root box experiment was conducted to investigate the effects of different biochars on plant growth and cadmium accumulation. The results showed that biochar significantly increased soil pH and reduced available cadmium. Intercropping favored the phytoextraction of cadmium by Sedum alfredii, while celery exhibited a decrease in cadmium uptake with biochar addition. These findings provide new insights into the application of engineered biochar for efficient remediation of cadmium-contaminated soils.

Summary: This study compared the sorption behavior of different carbon materials and NOM-loaded carbons on PCBs, finding that AC had a higher adsorption capacity than BC, but NOM loading had significantly different effects on the two materials. As sorption time increased, BC's sorption efficiency increased while the reduction effect of NOM on BC's sorption also increased, whereas AC's adsorption attenuation decreased over time.

Summary: Despite global restrictions, polychlorinated biphenyls (PCBs) are still present in the environment due to their persistence and anthropogenic production. This study investigated PCBs in tree bark across China to estimate atmospheric concentrations of dioxin-like PCBs and calculate toxic equivalents. The results showed that the 12 dioxin-like PCBs accounted for up to 34.7% of the total PCB concentration. Additionally, 41% of the sites exhibited carcinogenic risks, with PCB-126 and PCB-169 serving as convenient indicators of toxicity and risk.

Summary: The VL/Bi2WO6/PMS process was constructed to efficiently remove organics, with the degradation rate of carbamazepine (CBZ) increasing by over 33 times. The study demonstrated the activation of PMS by photogenerated holes and the formation of reactive species, which greatly enhanced the pollutant removal performance. This research provides a potential avenue for improving photocatalytic efficiency and widening the application of photocatalytic technology in wastewater purification.
