Summary: This study aimed to investigate the estrone degradation pathway and identify key degrading bacteria in the activated sludge of a major wastewater treatment plant in Bahrain. It was found that estrone degradation proceeds via the 4,5-seco pathway and is most likely mediated by alphaproteobacterial taxa.

Summary: This study aimed to investigate the interactions of sulfate and glucuronic acid conjugates of luteolin and naringenin with human serum albumin, cytochrome P450 enzymes, and organic anion transporting polypeptide transporters. The main findings indicate that sulfate conjugates formed more stable complexes with albumin than the parent flavonoids, while certain conjugates of luteolin and naringenin are potent inhibitors of OATP1B1 and/or OATP2B1 enzymes. These conjugated metabolites may play an important role in the pharmacokinetic interactions of these flavonoids.

Summary: Poly ferric sulfate (PFS) has a significant impact on methane production in activated sludge, leading to decreased methane potential and production rate, as well as extended lag time. PFS causes physical enmeshment, disrupts enzyme activity, and inhibits the bioprocess of hydrolysis, acidogenesis, and methanogenesis.

Summary: Anaerobic digestion is a commonly used method for treating waste activated sludge, and natural zeolite has the potential to improve methane production from this process. The optimal dosage of natural zeolite was found to be 0.1 g zeolite/g volatile suspended solids, resulting in a 20.1% increase in methane yield compared to the control. Natural zeolite had a greater effect on protein transfer and conversion than polysaccharides, and it improved the hydrolysis, acidification, and methanogenesis stages of anaerobic digestion. The dosages of natural zeolite also influenced bacterial and archaeal communities in biofilm and suspension.

Summary: This study investigated the use of ferrous-iron (Fe(II))-activated sulfite to overcome the slow hydrolysis and low acid production efficiency of waste-activated sludge (WAS) in traditional anaerobic fermentation. The results showed that Fe(II)-activated sulfite significantly promoted the breakdown of extracellular polymers and the production of short-chain fatty acids (SCFAs). The highest concentration of SCFAs reached 7326.5 mg COD/L under the optimal dosage of Fe(II)/S(IV). The analysis also revealed that Fe(II)-activated sulfite had a synergistic effect on sludge cell rupture and extracellular polymer stripping, generating key radicals such as SO4- and OH.

Summary: Efficient dewatering of sewage sludge is achieved using the combination process of chalcopyrite and sodium percarbonate (SPC). This process effectively weakens the water-holding capacity and hydrophilicity of sludge, leading to improved sludge-water separation. The chalcopyrite + SPC system generates reactive oxygen species that degrade the macromolecular extracellular polymeric substances (EPS), reduce water-holding affinity, and enhance self-flocculation and flowability. This system can be considered as an economically advantageous and environmentally friendly alternative to Fenton/Fenton-like strategies for sludge dewaterability.

Summary: In managing chemicals in the environment, efforts should be focused on substances posing the greatest threats. Policymakers often struggle with uncertainties about evidence and restorative actions, and broader adoption of weight-of-evidence approaches is urged. Progress requires long-term monitoring of wildlife and chemicals, as well as structured evidence collection for protecting ecosystems and human health.

Summary: The presence of pharmaceuticals in the environment, especially in aquatic environments, has been a topic of concern for over 20 years. However, the two most important questions regarding pharmaceuticals in the environment - assessing their threat compared to other stressors and identifying which pharmaceuticals are of concern - remain unanswered. These key questions have received little attention despite being identified as crucial a decade ago. Addressing these questions is essential for effective environmental protection.

Summary: Antidepressants are commonly prescribed drugs, but their adverse effects on humans and aquatic organisms are not well known. A study in Japan developed an assay to detect the inhibitory activities of antidepressants in wastewater, but the specific drugs responsible were unclear. This study prioritized antidepressants in effluent wastewater in England and Japan based on various factors, and found that sertraline and O-desmethylvenlafaxine had the highest contribution to inhibitory activities against serotonin transporters.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
