Summary: Ultraviolet disinfection is a promising solution for decentralized drinking water systems, but photorepair of pathogens after UV disinfection poses a health risk. This study constructed a quantitative microbial risk assessment (QMRA) for photorepair after UV disinfection of drinking water in a decentralized system. The risk of infection was found to be below 1-in-10,000 under certain conditions. The model can be expanded to other pathogens and used to inform the placement of community water access points to reduce photorepair risk and ensure safe storage of UV disinfected water.

Summary: This research explores the application of advanced oxidation processes (AOPs) for wastewater reclamation at pilot scale, which has been a major limitation in this field. Pilot-scale studies on sulfate radical-based AOPs (SR-AOPs) are rare, although there has been an increasing interest in them in recent years. The activation of peroxymonosulfate (PMS) can be enhanced by UV-A radiation or other oxidants like hydrogen peroxide (H2O2) or ozone (O3), leading to more efficient processes with lower reagent consumption. The combination of 0.5 mM PMS and 0.25 g·h-1 O3 showed the fastest inactivation of Enterococcus faecalis, achieving complete inactivation in less than 45 minutes. The combination of PMS, H2O2, and UV-A radiation also exhibited significant synergy to achieve total inactivation in less than 120 minutes, albeit with lower performance than the PMS/O3 system. Mechanistic studies revealed that the sulfate radical (SO4-) was responsible for bacterial inactivation in the PMS/O3 system, while the dominant species varied in the PMS/H2O2/UV-A system depending on the molar ratio of the oxidants. The treatments studied were effective in simultaneously eliminating pathogenic microorganisms such as Enterococcus faecalis, Escherichia coli, and Staphylococcus aureus, making this technology a viable alternative to conventional disinfection treatments.

Summary: Solar driven advanced oxidation processes (AOPs) such as SPF and SCL show promising potential for disinfection of roof-harvested rainwater, with SPF and SCL being the most effective in controlling bacterial regrowth after treatment. UV-C radiation, while fast in disinfection, was less effective in controlling bacterial regrowth.

Summary: The high transmission rate of COVID-19 has led to the use of various disinfection techniques, including hydrogen peroxide vaporization, microwave generating steam, UV radiation, and dry heat-ing, to prevent the further spread of the virus. Chemical-based techniques are commonly used for sanitization but may have unknown effects on human health and the environment. UV lamp-based radiation sanitization has limitations in penetrating different materials, and the use of UV-C in open environments is limited due to its harmful effects on human skin and eyes. Far UV-C (222 nm) technology has emerged as a potential option for sanitization in open areas and the degradation of microorganisms. This review evaluates the technical aspects of UV and the control of COVID-19 spread in the atmosphere, including the possibility of human body sanitization in working conditions.

Summary: This study investigated the effect of flow channel configuration on the water disinfection efficiency of a photoreactor with UV-C LEDs. The results showed that the serpentine and spiral configurations had similar microbial residence times, but the serpentine configuration had higher efficiency in Escherichia coli inactivation due to its high mixing efficiency. Although the pin configuration achieved the highest average UV fluence, the E. coli inactivation value in this configuration was low because some microbes received insufficient UV fluence. The study modified the pin configuration and found that it effectively increased the UV fluence received by microbes and eliminated low-fluence particles.

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.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. 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.
