Summary: Exposure to endocrine-disrupting chemicals (EDCs) can lead to a variety of disorders by disrupting the complex endocrine signaling pathways that regulate development, physiology, and behavior across the body. The mechanisms of endocrine disruption, such as gene regulation and DNA/protein binding, are linked to differences in individual susceptibility within diverse populations. Research is needed to further understand how gene-environment interactions across these pathways may contribute to differences in susceptibility to EDCs, with a focus on the intricate thyroid pathway.

Summary: Endocrine-disrupting chemicals (EDCs) are widely spread pollutants that have raised concerns about their impacts on reproductive health. Diminished ovarian reserve (DOR) is a disorder of ovarian function, and the association between EDCs and DOR has been inconsistent. In this study, we found that the likelihood of DOR significantly increased with rising levels of a mixture of 21 EDCs, and specific chemicals within the mixture were driving this association. These findings emphasize the importance of considering the effects of EDC mixtures on female reproductive health.

Summary: UV/chlorine process is effective in eliminating pathogens and refractory micro-pollutants in the reclamation of municipal secondary effluent. However, the high organic nitrogen content of effluent organic matter (EfOM) can lead to the formation of nitrogenous disinfection byproducts (N-DBPs) of health concern. This study tracked the molecular-level changes of hydrophobic (HPO) and transphilic (TPI) EfOM fractions during UV/chlorine treatment and observed the formation of diverse and intense N-DBPs. Toxicity bioassays showed that these N-DBPs can induce oxidative stress-induced DNA damage. The study highlights the importance of evaluating EfOM characteristics and transformation for the practical application of the UV/chlorine process.

Summary: The status of emerging contaminant profiles in Southeast Asia is unclear and often overshadowed by research conducted in developed regions. High population density and poor sanitation infrastructure in Southeast Asia introduce large amounts of emerging contaminants into the aquatic environment. Antibiotics, nonsteroidal anti-inflammatory drugs, per- and polyfluoroalkyl substances, and phthalate esters are among the most frequently studied groups of emerging contaminants in this region. Overutilization of antibiotics and pesticides in Southeast Asia's agrarian economies poses a major threat to aquatic environments and human health.

Summary: This study reveals that the commonly occurring manganese(IV) secondary mineral birnessite can catalyze the chlorination of guaiacol, a natural organic compound found in lignocellulose. The formation of chloroguaiacols is dependent on the concentration of chloride, and oxygen is not required for the MnO2-mediated chlorination process. This mechanism can explain the detection of organochlorines in forest soils, where manganese accumulation during the decomposition of wood and leaf litter occurs.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
