Summary: The study reported the removal efficiencies of eight typical EDCs at two domestic WWTPs in Dongguan City, China, through instrumental analysis and bioassay results. Despite high removal rates, bioassays revealed the presence of steroidogenesis-disrupting effects and ER/AhR activities, indicating potential ecological risks that cannot be ignored. Nonylphenol was identified as the major chemical type present among the tested EDCs, while estrone was found to be the most hazardous chemical in terms of ecological risk assessment.

Summary: An integrated study was conducted on the occurrence and fate of eleven organophosphate esters (OPEs) in two wastewater treatment plants (WWTPs) in Thessaloniki, Greece. The study found that biodegradation and sorption onto sludge were the main removal mechanisms for OPEs. The emissions of OPEs through effluents and sludge did not pose considerable risk to the aquatic and terrestrial environment.

Summary: This study investigated the presence of bisphenols (BPs) in drinking water and evaluated their removal efficiency, estrogenic activity, and human exposure risk. The results showed that all nine BPs were detected in the raw water, with BPA being the main substance. The treatment processes in DWTPs had a significant removal efficiency for BPs, and a combination of physical adsorption and biological oxidation showed the best removal effect. The health risk evaluation indicated that BPs did not pose a significant health risk through drinking water.

Summary: This study investigated the occurrence and removal efficiency of pollutants, estrogenic effects, and fecal coliform in sewage from village sewage treatment plants (STPs) in the Yangtze River Basin. The study found significant seasonal and spatial variability in the water quality of sewage from village STPs. The removal rates of pollutants and estrogenic compounds were low, and ultraviolet disinfection was unable to meet the discharge standard for fecal coliform. Sequential chlorine-UV disinfection was found to be effective in improving the removal rate of estrogenic effects and achieving up-to-standard discharge of fecal coliform.

Summary: The increase in anthropogenic impact has led to the constant discharge of new substances into the environment, including endocrine-disrupting compounds (EDCs). EDCs have drawn global attention due to their potential health risks to animals and humans' endocrine systems, as well as the uncertainty surrounding their long-term effects. Recent advancements in analytical technologies have allowed for the identification of EDCs and the proposition of suitable treatment processes, with many research publications focusing on detection methods and treatment processes for EDCs over the last decade.

Summary: The widespread occurrence of artificial sweeteners in wastewater treatment plants in China poses potential risks to aquatic environments, with sucralose and aspartame showing higher concentrations and potential risk. The overall removal efficiency of artificial sweeteners in WWTPs varied greatly, with southern cities showing higher per capita mass loads than northern cities, correlating with population density. Advanced treatment processes like UV/H2O2 and UV/PDS were found to be more effective in removing artificial sweeteners, with UV/PDS being the most suitable for removing sucralose and acesulfame.

Summary: Anammox is an efficient nitrogen removal technique, but its long start-up time limits industrial application, therefore the use of carriers to accelerate start-ups is essential. Preservation of anammox bacteria is crucial, and adding polyurethane sponge can shorten the start-up and reactivation time by retaining more anammox bacteria in the reactor.

Summary: This study investigated the abundance, characteristics, and retention of microplastics (MPs) in different sewage treatment plants (STPs), as well as the ecological risks posed by MPs entering the environment. The results showed that a significant portion of MPs can be trapped and transferred into dewatered sludge during the sewage treatment process. The dominant colors of MPs were transparent, black, blue, red, pale brown, green, and gray, with the main species being polypropylene and polyethylene. Furthermore, MPs were found to be absorbed by oyster mushrooms, with fibrous materials widely distributed in their stipes and pileus.

Summary: This study investigated the aquatic toxic effects and mechanisms of MoS2 nanosheets on the freshwater green microalgae Selenastrum capricornutum. The results showed that low concentrations of single-layer MoS2 nanosheets stimulated algal growth, while higher concentrations inhibited growth through oxidative damage and membrane destruction. Additionally, MoS2 nanosheets accelerated the secretion of extracellular polymeric substances and changed their fluorescent components, thus influencing algal growth.
