Summary: This study investigates the effect of dry-wet ratios and temperature on the chloride corrosion resistance of concrete. Results show that a higher dry-wet ratio intensifies the deterioration of concrete performance. Compared to a dry-wet ratio of 1:3, a dry-wet ratio of 3:1 leads to decreased strength and increased chloride content and erosion depth. Additionally, variable temperature cycles accelerate the decay of mechanical strength and chloride erosion resistance in concrete.

Summary: Atmospheric aerosol deposition is an important nutrient source for primary production in the low latitude oligotrophic ocean. However, the response of phytoplankton to aerosol deposition events, in terms of magnitude and community composition, is not well understood. In this study, we investigated this using field and satellite observations in the subtropical North Atlantic. We found that wet deposition events led to a doubling of chlorophyll a and a shift in dominance from Synechococcus to Prochlorococcus, suggesting the importance of aerosol-derived nitrogen in alleviating nutrient limitation and driving rapid phytoplankton response.

Summary: All ecosystems face anthropogenic contaminants, leading to numerous toxicology studies. Inconsistencies in expressing contaminant concentrations in wet or dry mass units and the lack of reporting tissue composition render cross-study comparisons challenging. This study explored the effects of variables on moisture and lipid contents in red fox tissues and their consequence on contaminant concentrations when converting between wet and dry mass units. Recommendations include systematic reporting of tissue composition and the use of tissue/species specific conversion factors.

Summary: This article studies the application of the flux globalization based central-upwind scheme in the Saint-Venant system of shallow water equations. It is found that the scheme can preserve moving-water equilibria but fails to preserve lake-at-rest steady states. The authors modify the computation of the global flux variable and develop a well-balanced scheme to accurately handle both still- and moving-water equilibria. Additionally, the scheme is extended to handle dry and/or almost dry areas using a hybrid approach.

Summary: This study investigated the effects and mechanisms of microplastics and ciprofloxacin on phosphorus removal by phosphorus-accumulating organisms. The findings show that microplastics reduce the toxicity of ciprofloxacin and ciprofloxacin stimulates the production of extracellular polymeric substances, thereby reducing the stress on phosphorus-accumulating organisms. These results contribute to understanding the effects of emerging pollutants in sewage systems and propose measures to improve biological phosphorus removal.

Summary: With the increase in industrialization and population growth globally, proper treatment of sewage sludge, which is generated in large amounts, has become necessary. The pyrolysis of sewage sludge into biochar has proven to be a sustainable solution for pollutant adsorption and waste treatment. This study investigated the adsorption behavior of sulfamethoxazole (SMX) antibiotics on sludge-based biochar from different sources and ZnCl2-modified biochar. The findings revealed that raw sludge-based biochar exhibited the highest adsorption capacity, and the pore-forming effect of ZnCl2 significantly increased the adsorption. Various mechanisms, including electrostatic interactions, pore filling, hydrophobic interactions, hydrogen bonding, and pi-pi interactions, were involved in the adsorption process. This research demonstrates the potential of sewage sludge biochar for the treatment of antibiotics-containing wastewater.
