Summary: Landfill gas emissions, including methane and volatile organic compounds (VOCs), are effectively reduced by using up-flow biofilters packed with inorganic materials. Different pollutant mixtures were treated with varying empty bed residence times (EBRTs), resulting in different removal efficiencies for methane and VOCs. The highest removal efficiency for methane was achieved at a longer EBRT, while the highest removal efficiencies for VOCs were obtained at a shorter EBRT, indicating different degradation patterns for different compounds.

Summary: Air-fuel equivalence ratio has a significant impact on engine emissions, with higher ratios leading to lower NOX emissions but higher organic compound emissions. For ratios greater than 3, a significant amount of uncombusted fuel passes through the engine, resulting in extremely low NOX concentrations in the exhaust. Lower ratios are associated with the formation of more reactive organic compounds and increased NOX emissions. The study found lower NOX emissions but significantly higher volatile organic compound emissions compared to regulatory emissions inventory. These discrepancies may be due to changes in engine emissions at lower loads and with aging. This work improves emissions inventories, strengthens regulatory efforts, and enhances photochemical models' ability to predict the atmospheric impacts of oil and gas development.

Summary: This study reveals the stereoselective degradation patterns and biodegradation mechanisms of metolachlor and napropamide in integrated vertical flow constructed wetlands. The higher interphase transferability of napropamide leads to higher degradation rates, while the enantiomers of metolachlor and napropamide demonstrate highly selective biodegradation patterns. The antioxidant enzyme activities and fluorescence parameters of plants are positively correlated with the degradation efficiency and enantioselectivity of the pesticides. Adaptive regulations by plants promote the growth of microbial genera and the enrichment of specific herbicide-degrading bacteria, facilitating the degradation of the pesticides. The presence of Ferruginibacter contributes to the co-removal of napropamide and NO3--N.

Summary: The larvae of Pachnoda marginata have a complex gut microbiota capable of converting lignocellulosic biomass effectively. Enrichment cultures were established using wheat straw as a substrate in an alkaline medium from the midgut and hindgut contents of the beetle larva under mesophilic conditions. The inoculum preparation method significantly influenced methane production and acetic acid concentrations in the cultures. Dysgonomonadaceae, Heliobacteriaceae, Ruminococcaceae, and Marinilabiliaceae were found to be the most abundant bacterial families, while Methanobrevibacter, Methanoculleus, and Methanosarcina were the most abundant methanogenic genera. The findings suggest that incomplete conversion of volatile fatty acids to methane may occur in samples processed with certain inoculation preparations.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
