Summary: The pyrolysis of biomass containing excessive heavy metals can result in heavy metal contaminated biochar (BC). In addition to higher charring temperature, particle size of BC also plays a critical role in the content of heavy metals and its ecotoxicity. Content and chemical forms of cadmium (Cd) in BC fractions as well as the related algal toxicity were examined. The results showed that particle size significantly modified the chemical forms and ecotoxicity of Cd in BC, which has important implications for understanding the behavior and potential risk of heavy metal contaminated BC in the environment.

Summary: Worldwide rapid urbanization and development have led to the release and dispersion of anthropogenic heavy metals, posing serious threats to aquatic ecosystems and human health. Although various methods for removing heavy metal ions from aqueous solutions have been explored, there is still a need for improvement in the efficient and pertinent treatment of heavy metal pollution. Adsorption is considered the best technique for heavy metal removal, and metal-organic frameworks (MOFs) are recognized as one of the most promising emerging adsorbents with excellent adsorption properties. This review provides a comprehensive overview of MOFs synthesis techniques, functionalization methods, and adsorption mechanisms, as well as a detailed comparison of their applications in heavy metal removal, aiming to offer a strong reference for MOFs synthesis and a feasible solution for heavy metal treatment.

Summary: In this study, the characteristics of corn stalk biochar and its adsorption mechanisms for two heavy metals, Pb and Cd, were investigated. The results showed that the corn stalk biochar exhibited a porous structure and contained functional groups such as phenol and carboxyl groups, which played important roles in adsorption. The adsorption capacity was influenced by factors such as pH, temperature, and ionic strength. The kinetic experiments indicated that the adsorption processes could be described by the pseudo-first order model, and the adsorption isotherm could be fitted well by the Langmuir model. Overall, this study provides insights into the potential application of corn stalk biochar for metal pollution treatment in wastewater.

Summary: Due to their high biological toxicity, the simultaneous removal of lead (Pb (II)) and methylene blue (MB) is a challenging problem. In this study, a new material called 13-cyclodextrin (13-CD) modified magnetic alginate/biochar (13-CD@MBCP) was developed. The material showed efficient removal of contaminants over a wide pH range. The presence of MB facilitated the elimination of Pb (II), while the presence of Pb (II) inhibited the uptake of MB. The study revealed the important roles of electrostatic attraction, complexation, 7C-7C interactions, host-guest effect, and H-bonding in the removal of both Pb (II) and MB. The 13-CD@MBCP showed good renewability after four cycles, making it a promising remediation material for Pb (II)/MB adsorption in aqueous environments.

Summary: In this study, cellulose nanowhiskers (CNW)/chitosan nanocomposite films were synthesized using deep eutectic solvents (DES) to change the chemical structures. The incorporation of CNW into chitosan films resulted in sharper and stronger peaks, as well as an infusion of more amide elements. The mechanical properties of the nanocomposite films, including tensile strength (TS), Young's modulus (YM), and elongation at break, were enhanced with CNW filler, although YM and TS decreased due to the hygroscopic nature of the films. DES, as a green solvent, has the potential to replace ionic liquids in materials synthesis while reducing the environmental impact of chemical production.

Summary: This study evaluated the impact of exposure to poly-styrene nanoparticles (PS NPs) on the behavior, brain antioxidant activity, and DNA damage in male Swiss mice. It was found that mice exposed to PS NPs exhibited anxiolytic-like behavior and altered defensive response when confronted with a predator. Additionally, the exposure to PS NPs led to reduced brain antioxidant activity and increased DNA damage. These findings highlight the potential impact of PS NPs on mammals and underscore the ecotoxicological risks associated with their dispersion in natural environments.

Summary: Water is a major source of human diseases due to contamination with bacteria and other pathogenic microorganisms. This review focuses on microbial hazards in water and wastewater, and the use of sonochemical reactors (SCRs) combined with advanced oxidation processes (AOPs) for disinfection. Various types of cavitation reactors, including acoustic cavitation reactors (ACRs) and hydrodynamic cavitation reactors (HCRs), have been employed for the treatment of contaminated waters. Bacterial degradation is primarily caused by thinning of microbial membranes, local warming, and free radical generation due to cavitation. The mechanisms and effects of cavitation in the disinfection process are still poorly understood.

Summary: Emerging pollutants (EPs) are toxins with low concentrations but substantial toxicity that have gained attention due to environmental concerns. These trace contaminants can accumulate in various sources and pose a public health risk when they make their way into human bodies. Biochar adsorbents have been used as low-cost and effective means for treating wastewater and removing EPs. However, improvements are needed for the treatment of emulsifiable concentrated water using biochar adsorbents. Modified biochar (mBC) techniques have been investigated to confiscate EPs from effluents, resulting in different impacts and adsorption processes. Therefore, it is important to systematically evaluate and assimilate information regarding the adsorption of EPs by modified biochar.

Summary: The presence of heavy metal chromium (VI) in water environments can cause various diseases in humans. This review analyzes the effectiveness of different adsorbents for chromium (VI) adsorption, including biosorbents, activated carbon, nanocomposites, and polyaniline (PANI). It also examines how operational parameters such as initial concentration, temperature, pH, contact time, and adsorbent dosage affect the adsorption capacity. The study finds that biosorbents, activated carbons, and certain nanocomposites are effective in achieving high adsorption capacity, and operational parameters significantly influence the adsorption capacity. The evaluation of different adsorbents provides valuable insights for treating water contaminated with chromium (VI).
