The AIPBR was operated with synthetic wastewater containing ammonium concentrations of 1800 ± 100 mg/L and salinity gradients ranging from 1 to 10 g/L, followed by a fixed salinity period at 6 g/L, with ammonium concentrations approximately 850 mg/L.

Anammox bacteria adapted by enriching genes involved in the synthesis of osmoprotective compounds and activating energy-producing pathways like the tricarboxylic acid cycle (TCA). These adaptations, along with modifications in membrane composition, were essential for sustaining system stability under elevated salinity. Under prolonged high salinity stress, anaerobic ammonium oxidizing (AnAOB) exhibited improved salt tolerance, maintaining a total nitrogen removal efficiency above 85 % and stabilizing after an adaptation phase. The metagenomic data revealed a marked enrichment of genes associated with ion transport, stress response mechanisms, and DNA repair pathways.

We hypothesize that exposure to a mixture of BPA and its substitutes will enhance their endocrine-disruptive effects, disrupt steroid hormone homeostasis, and further impair reproductive system functionality. In the animal study, both female and male mice were exposed to 333 μg/kg of BPA, BPF, BPS, their mixture (333 μg/kg (MIXL), and 1 mg/kg (MIXH)) via gavage daily for four weeks. The study demonstrated that bisphenols (BPs) affected the expression of genes related to steroid hormone synthesis. The MIXL group of female mice exhibited an increasing trend in estradiol (E2) levels and a decreasing trend in progesterone (Pg) and testosterone (TT) levels. Additionally, follicular development was impacted, resulting in an increased number of atretic follicles. In contrast, a significant increase in E2 concentration and disruption of testicular morphology were observed in the MIXH group of male mice, accompanied by a decline in sperm quality. Importantly, these results were corroborated by a population-based investigation. Collectively, the animal experiments indicate that mixed exposure to BPs disrupts hormone levels and adversely affects reproductive function, while epidemiological evidence further establishes correlative links between bisphenols and hormone levels.

This study investigated CO₂ fluxes (<em>f</em>CO₂) in two different backwater bays (Hanfeng Lake and Gaoyang Lake) within the Three Gorges Reservoir (TGR), to reveal the spatio-temporal dynamics and driving factors of CO₂ emissions. The two backwater bays serve as minor sources of CO₂ emissions, exhibiting lower <em>f</em>CO₂ compared to other water areas within the TGR. In the subsiding and low water level periods of the TGR, the <em>f</em>CO₂ in the two backwater bays were significantly lower, with some areas even converting into CO₂ sinks due to extensive eutrophication. However, the water flow backward caused by the TGR water level elevation simultaneously enhances CO₂ emissions by diluting algae density and constraining primary production. We highlighted that nutrients enrichment, eutrophication, and water level fluctuations co-dominate the temporal dynamics of CO₂ emissions from backwater bays in the TGR. The CO₂ fluxes decreased from upstream to downstream in the two backwater bays. The spatial distribution of nutrients and related algal density are critical factors driving this pattern.
