Summary: Microplastics (MPs) are widely distributed and can carry pollutants into organisms, resulting in chemical accumulation. This study investigated the desorption mechanism of antibiotics carried by tire wear particles (TWP) in simulated human gastrointestinal fluid and fish intestinal fluid. The study found that photoaged TWP in an aquatic environment had cracks, pores, depressions, and additional adsorption sites for pollutants. The desorption rate was higher in simulated human gastric fluid than fish intestinal fluid due to competition for adsorption sites and potential dissolution of antibiotics. This study enhances our understanding of TWP toxicity and has implications for risk assessments.

Summary: Activated carbon derived from waste tires exhibited higher adsorption capacities for heavy metal ions than commercial activated carbon, with electrostatic attraction and surface complexation being the dominant mechanisms. In contrast, commercial activated carbon primarily relied on ion exchange for heavy metal removal.

Summary: This study investigated the adsorption process of heavy metals Pb2+ and Cd2+ on tire wear particles. The results showed that the adsorption kinetics followed a pseudo-second-order rate equation with rate-controlling boundary layer adsorption and intraparticle diffusion process. The adsorption tendencies for Pb2+ and Cd2+ on the tire wear particles were studied, and the Freundlich and Dubinin-Radushkevich isotherms were found to be feasible for describing the adsorption. It was also found that the adsorption of Pb2+ and Cd2+ was mainly physisorption and the process was dependent on ambient conditions.

Summary: This study compared the adsorption behavior of lead (Pb(II)) onto environmentally-relevant tire wear particles (TWP), ultraviolet-aged polylactic acid microplastics (UV-PLA), and ultraviolet-aged polystyrene microplastics (UV-PS). The results showed that aging processes significantly improved the adsorption capacity of Pb(II), with TWP having the highest adsorption amount. The mechanisms of adsorption differed for each type of microplastic, with electrostatic interaction and complexation playing important roles. Furthermore, the presence of humic acid affected the adsorption capacity, and the desorption ability of Pb(II) varied among the different microplastics.

Summary: The research focused on improving the adsorption efficiency of geopolymer as an adsorbent for heavy metal ions and dyes removal. The adjustment of pH enhanced the rapid removal of methylene blue and nickel ions by exposing more negative charge adsorption sites. Additionally, the study found that the desorption of nickel ions was facilitated by a decrease in pH of the wash solution.

Summary: This study measured the concentrations of non-tailpipe particulate matter (PM2.5 and PM10) near two major highways in California and found that non-tailpipe emissions have become the dominant source of traffic emissions. Iron was the most abundant element in the measured PM10, while silicon was the second most abundant element in both PM2.5 and PM10. Furthermore, some metal elements were found to strongly correlate with brake wear indicators.

Summary: This study analyzed the composition distribution of five size-fractioned particle sizes in road dust collected from steel industrial complexes. The results showed an increase in the mass content of iron, manganese, and tire-wear particles as the particle size decreased. It was found that manual sweeping and water flushing were ineffective in removing fine particles, and magnetic separation and vacuum cleaning were recommended to reduce the exposure of fine particles.

Summary: This study investigates the treatment of heavy metal pollutants in water using red mud particle waste. The experiment explores the static adsorption of Pb2+ (or Cd2+ and Cu2+) by red mud particles and examines the effects of various factors on the adsorption performance. The results indicate that red mud particles exhibit different adsorption strengths for different heavy metal ions, with Pb2+ showing the highest adsorption capacity. Increasing the temperature enhances the adsorption of heavy metal ions. The preferred adsorption sequence of red mud under competitive conditions is Pb2+, Cd2+, and then Cu2+.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.

Summary: This study investigated the bacterial degradation of naphthalene (NPT) isolated from crude oil-contaminated soil. Bacillus sp. GN 3.4, a potential bacteria for NPT biodegradation, was isolated and the optimal conditions for NPT degradation were determined. The study suggests that Bacillus sp. GN 3.4 could potentially aid in bioremediation by eliminating NPT from the soil.
