Summary: The decomposition of Apocynin (ACN) was studied using an electrolytic approach combined with radiolysis employing gamma radiation. A photo-catalytic membrane reactor (PMR) with suspended and immobilised Sr-LaNiO3 was utilized for Apocynin breakdown. The impact of residual Sr-LaNiO3 on the PMR containing basic Sr-LaNiO3 was investigated for phase procedures. An RO membrane was integrated through the PMR under continuous conditions to improve water quality. ACN deterioration by the PMR with attached and immobilized Pt-LaNiO3 was similar in both methods at a moderate Sr-LaNiO3 dosage (0.8 g/L), but improved with larger Sr-LaNiO3 doses for the reactor with coupled Pt-LaNiO3.

Summary: The current study demonstrates efficient removal of xylene using a modified adsorbent made from avocado seed. The activated carbon surface was modified using titanium dioxide, resulting in significant performance on a surface area of 67.35 m2 g-1. Xylene concentration dropped at different temperatures, and the Thomas and Adams-Bohart model showed the best fit for describing the equilibrium adsorption data. SEM patterns showed increased porosity due to surface modification, while XRD and FTIR analyses did not reveal any structural distortion. This thorough analysis resulted in the removal of 93% of xylene using a cost-effective adsorbent.

Summary: All living things depend on their natural environment for various aspects of life and development. However, due to excessive greenhouse gas emissions, the Earth's climate system is experiencing negative impacts from global warming. Climate change-induced stresses, such as rising sea levels, hotter oceans, increased droughts and floods, and deteriorating water quality, pose threats to heavily populated areas and aquatic ecosystems worldwide. As a result, global aquatic ecosystems are rapidly deteriorating. This review explores the interaction between global warming and human influences along coastlines, highlighting the importance of long-term monitoring, ecological indicators, and understanding biodiversity and ecosystem responses to climate change. The implications of current climate change on marine biological processes, including historical changes and potential roles of aquatic systems in mitigating climate change effects, are discussed.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
