Summary: Glyphosate is a widely used herbicide that poses a threat to the environment and human health. This study evaluated the effectiveness of various oxidative processes in degrading glyphosate and analyzed the phytotoxicological effects of the oxidation products on maize seed germination. The photoelectro-Fenton treatment was found to be the most effective in degrading glyphosate and generating non-toxic by-products. Maize seed germination was not adversely affected by the oxidation products. However, a stimulatory effect of glyphosate was observed at low concentrations.

Summary: A pilot field study was conducted to assess the remediation efficiency of sodium persulphate (SPS) activated with calcium peroxide (CP) to degrade diesel from Arctic soil. The study found that the chemical oxidation process successfully removed 35% of the diesel over a 33-day period. The temperature increase during SPS activation was not significant, and the soil columns did not experience clogging from by-products.

Summary: In this work, waste tire-derived carbon was used as an electroactive material to manufacture a gas-diffusion cathode for electrochemical production of H2O2. Acidification with HNO3 was found to significantly enhance the H2O2 production. The cathode was also able to effectively degrade tinidazole (TNZ), a nitroimidazole antibiotic. The study demonstrates the potential of waste tires as a source of inexpensive carbon for in-situ H2O2 synthesis and water decontamination.

Summary: This study evaluates the effect of Fenton's reagents on wastewater odor and concentration, and demonstrates that the Fe2+/H2O2 system is the most effective in inhibiting odor formation and reducing odor concentration. By introducing Fe2+/H2O2, the generation of odors in wastewater can be effectively suppressed, resulting in a significant decrease in odor concentration.

Summary: The degradation of the emerging environmental contaminant tetrabromobisphenol S (TBBPS) by thermally activated persulfate (PDS) oxidation was systematically investigated. The results showed that this method can effectively remove TBBPS but may lead to potential risks of brominated disinfection by-products (DBPs).

Summary: Alkali activated materials (AAMs) can be used as an alternative to cement-based products or ceramics, and can incorporate large amounts of aluminosilicate rich materials. The sediments collected at hydropower plant dams were calcined and activated to improve their properties, and the mechanical performance of AAMs can be enhanced by adding fly ash or ladle slag.

Summary: This study assesses the prevalence and characteristics of microplastic pollution in the Arvand River, Iran. The study finds a wide range of microplastic concentrations in the water and sediment, with majority being fibers and colored black/grey and yellow/orange. Polyethylene terephthalate (PET) and polystyrene (PS) are the most abundant polymers in the water and sediment samples. The presence of urban wastewater effluents likely contributes to the microplastic pollution. The study highlights the need for interventions to reduce microplastic inputs to the river and sea.

Summary: This study investigated a control strategy for spore-forming bacteria (SFB) in drinking water treatment. The results showed that pre-oxidation, coagulation sedimentation, and UV-AOPs inactivation were effective in transforming, removing, and inactivating SFB spores. The study also demonstrated the enhanced inactivation of the most chlorine-resistant SFB strain by adding chemicals to the UV irradiation process. The findings provide valuable references for dealing with SFB outbreak risk in drinking water treatment.

Summary: The discharge of widely used fluorinated aromatics (FAs) leads to their notoriously high persistence and toxicity in natural environments. Defluorination is the key step for FAs pollutants detoxification. In this study, 4-fluorophenol (4-FP) was selected as a model compound to optimize the electrochemical hydrodefluorination (HDF) process and understand the reaction mechanism. The investigation showed that Rh coating outperformed Pd coating due to its higher reactivity towards C-F bond cleavage.

Summary: A simple technique for fabricating TiO2 thin film photocatalyst was developed in this work. The fabricated photocatalyst featured a homogeneous nanowire layer grown in situ on the Ti plate. The photocatalytic activity of the fabricated TiO2 thin film photocatalyst showed efficient degradation of RhB and CBZ under UVC irradiation, and the degradation kinetics were affected by the pH and the presence of Cl-, SO42-, or NO3-.
