Summary: Activated carbon injection coupled with bag filtering is a promising technology for the treatment of organic pollutants in the flue gas of coal-fired power plants. The removal efficiency of VOCs in the ACI+BF system is affected by factors such as adsorption temperature, VOC concentration, AC feeding rate, and residence time. The process of VOC removal by the ACI+BF system can be divided into adsorption in the pipeline and adsorption in the bag filter, with the bag filter playing an important role in the overall removal efficiency. Increasing the pipeline length and reducing the frequency of filter bag cleaning can enhance the removal efficiency of organic pollutants.

Summary: Antibiotics have been detected in small environmental matrices worldwide, causing concern. The use of biochar adsorbents made from residual sewage sludge can remove pollutants and promote pollutant reduction and reuse, which is significant for green development. In this study, a modified biochar-based adsorbent (PBA) was used for the removal of norfloxacin (NOR) from wastewater with an overall removal efficiency of 84% achieved in 4 hours. The adsorption behavior followed the Lagergren pseudo-second kinetic model and Langmuir model, and the capacity of PBA for NOR reached 8.69 mg·L-1. A total removal efficiency of 62% was obtained for five mixed quinolone antibiotics using PBA, which could be regenerated and reused five times. This study presents a new method for utilizing sewage sludge as a bio-waste for antibiotic removal from wastewater.

Summary: This study investigated the transformations of heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) in rhizosphere soils and adaptive responses of rhizobacterial community under real field conditions during the growth stages of early rice and late rice. The results showed that the rhizosphere soils of the late rice field had mild pollution of Cd and PAHs compared to those of the early rice field. The relative abundance of bioavailable Cd and bioavailable As in rhizosphere soil increased before the heading stage but decreased at the subsequent growth stage, while the content of EPAHs decreased gradually during the entire growth period. Rhizobacteria interacted more intensively with the co-pollutant at the tillering and heading stages, and genes involved in HM-resistance and PAH-degradation were significantly enhanced. The contents of bio-Cd and bio-As in the rhizosphere soil of early rice were higher than that of late rice at each growth stage, especially at the heading stage. Bio-Cd, EPAHs, and organic matter were key factors influencing the community structure of rhizobacteria. The results of this study provide valuable insights into the interactions between HM-PAH co-pollutant and rhizobacterial community under real field conditions and contribute to the development of in-situ rhizosphere remediation techniques for contaminated paddy fields.

Summary: Global concern over microplastics is increasing due to their potential threat to ecosystems and human health. This study investigated the release of microplastics from different types of commercial disposable cups under daily use conditions. The results showed that all tested cups released microplastics, with irregularly shaped particles predominating and sizes mostly smaller than 20 µm. There was no significant difference in the quantity of microplastics released among the different cup types. High temperatures and acidic carbonated beverages were found to promote microplastic release.

Summary: A study was conducted to clarify the sorption mechanism and removal efficiency of PAHs using waste biomass-based magnetic sorbents. The sorption performance of magnetic Myriophyllum aquaticum biomass (MMaB) for PAHs was investigated, and various factors such as contact time, initial concentration, pH, ionic strength, and temperature were evaluated. The results showed that the sorption of PAHs on MMaB followed a pseudo-second-order kinetic model and was controlled by chemisorption. The as-prepared MMaB sorbent exhibited good cycling performance and has great potential as an easily-prepared and efficient biosorbent for PAH removal from wastewater.
