Summary: This study evaluated the ability of a constructed wetland with a bacterial-plant consortium to biodegrade chlorpyrifos and its major metabolites. Through the collaboration of bacterial strains and wetland plants, chlorpyrifos degradation without the production of harmful metabolites was achieved.

Summary: This review focuses on the sources, geochemical behavior, uptake, toxicity, detoxification, and bioremediation strategies of Uranium in soil-plant systems. It highlights mining activities as the main source of soil Uranium contamination, with Uranium mainly accumulating in plant roots but being translocated to aerial parts in some species. Plants tolerate Uranium toxicity through various defense mechanisms.

Summary: The study shows that floating treatment wetlands can effectively remove nitrogen and phosphorus from water bodies. Different plant species have varying efficiency in fixing nitrogen and phosphorus, but the amounts of nitrogen and phosphorus removed after plant harvest are similar. Harvesting plants can effectively reduce the nitrogen and phosphorus content in surface waters.

Summary: Human activities in wetlands and seasonal changes can affect the concentrations of heavy metals in soil and the types of marsh vegetation. The study found that different types of wetland vegetation and the ion composition of the soil can influence the levels of heavy metals.

Summary: Biodegradation is a sustainable and cost-effective solution for groundwater pollution. In this study, the microbial populations involved in the biodegradation of poly-contaminants in a heavily contaminated groundwater pipeline were investigated. The microbial communities were analyzed using genome-resolved metagenomic analysis, revealing the changing microbial communities in a highly effective groundwater treatment system.

Summary: This study investigates the microbial communities involved in the biodegradation of poly-contaminants in a groundwater treatment system. The genome-resolved metagenomic analysis revealed significant differences in microbial populations between the plant and the contaminated park groundwater. The findings provide valuable insights into the efficacy of microbial biodegradation in treating complex groundwater contaminants.

Summary: Polycyclic aromatic hydrocarbons (PAHs) pollution is a global ecological soil problem. The addition of nano-SiO2 increased the abundance of Acidobacteria and the genera related to PAH degradation. The S. spectabile remediation system assisted by two nanomaterials was effective for the removal of PAHs from soil, and the transfer of PAHs to easily harvested aboveground plant parts was especially worthy of attention.

Summary: Plant-mediated CH4 emission is an important part of the ecosystem CH4 emission from vegetated wetlands. The relationships between plant-mediated CH4 emissions and inundation depth are still uncertain. Inundation depth decreased soil CH4 emissions but increased ecosystem CH4 emissions. Plant-mediated CH4 transport from Phragmites australis accounted for 99% of total ecosystem CH4 emissions, and inundation depth strongly stimulated plant-mediated CH4 emission.

Summary: This study investigated the batch experiment with different aquifer materials using persulfate as a chemical oxidant to oxidize organic contaminants. The results showed that BTEX could be preferentially removed with the addition of persulfate, while ethanol could compete with sulfate radical and potentially inhibit the biodegradation of BTEX.

Summary: Soil degradation through salinization and pollution by toxic compounds is a significant threat to coastal wetlands. Bioremediation using plants, biochar, and microbes is a cost-effective option for remediation. Biochar enhances plant/microbe growth and can effectively remediate petroleum hydrocarbons (PHCs) in salinized soils. Plant-microbe interactions mediated rhizodegradation and microbial respiration is more active in biochar amendments. The use of biochar, plants, and microbes is recommended for sustainable and practical remediation of PHCs and salinization.

Summary: The study evaluated the effects of sugarcane bagasse biochar and Bacillus sp. MN54 on phytoremediation of petroleum hydrocarbons and growth of maize in diesel contaminated soil. The results showed that the addition of biochar and strain MN54 significantly reduced the toxic effects of PHs on plant growth and physiology. Additionally, the combined supplementation of strain MN54 and biochar further enhanced plant growth and PHs removal from soil.

Summary: The effectiveness of floating treatment wetland (FTW) for metal removal is influenced by nutrient availability in the water, according to a study. The research found that the metal uptake rates of plants in nutrient-rich lake water were slower compared to nutrient-deficient tap water.

Summary: The selective aromatization of n-hexane was achieved by using CO2 over a Zn modified HZSM-5 catalyst, which effectively suppressed the hydrogen transfer between olefins and aromatics. This was achieved by the dynamic evolution of the Zn-OH+-(CO)-O-Zn structure, which removed in situ H originated from C-H activation. As a result, the Zn/ZSM-5-CO2 catalyst exhibited a record high BTEX yield of 49.7%, nearly 10% higher than the Zn/ZSM-5-N2 catalyst (40.3%), indicating its potential for profitable utilization of petrochemical resources.
