A school-based study was conducted in Tianjin, China, including 212,566 students in grades 4-6. The 3-yr mean concentrations of particulate matter with aerodynamic diameter ≤ 2.5 μm (PM_2.5), its major components (sulfate (SO₄^2-), nitrate (NO₃^-), ammonium (NH₄⁺), organic matter (OM), and black carbon (BC)), and ozone (O₃) were estimated using machine-learning exposure models and linked to school locations. Restricted cubic splines and quartile-based modified Poisson models were used to assess single-pollutant exposure-response relationships, and quantile-based g-computation was applied to estimate joint pollutant associations. In single-pollutant models, the highest quartile of SO₄^2- was associated with higher myopia prevalence compared with the lowest quartile (PR = 1.10; 95% CI, 1.07-1.13). O₃ showed weaker and non-monotonic positive patterns (Q4 vs Q1: PR = 1.03; 95% CI, 1.00-1.05). In mixture analyses, a one-quartile increase in joint exposure was associated with higher myopia prevalence (PR = 1.017; 95% CI, 1.007-1.027).

It markedly impaired olfactory signal transduction and processing (e.g., gnal; ∼56% decrease), while visual function was more severely impaired in females (e.g., a 48% decrease in velocity during visually guided behavior). Correlation analysis further showed that Cu induced coordinated changes between olfactory tissue and eyes. Meanwhile, such olfactory and visual impairments, together with altered neurotransmitter levels and disruptive appetite regulation (e.g., ∼1.2-fold increases in the orexigenic neuropeptide Y (NPY) and the anorexigenic pro-opiomelanocortin (POMC)), may collectively contribute to the 6.0-17% decline in feeding-related behavior.

This is especially true in high-altitude alpine environments, where abiotic stress is naturally heightened, but which so far have received little attention in environmental pollution studies. As we were interested in the tolerance mechanisms at play on very fine spatiotemporal scales for alpine plants growing under multi-stress conditions, we chose Cardamine resedifolia as our biological model. This plant is indeed frequently found in areas contaminated by Trace Metals and Metalloids and Polycyclic Aromatic Hydrocarbons in high elevation. We studied populations from former copper, silver-lead, and coal mines in alpine environments, along with populations growing on nearby reference soils. We measured genetic variability within populations as well as genetic differentiation between them, and tested for local adaptation to soil contamination using reciprocal transplants. Population pairs showing signs of local adaptation were then examined using genome scans to identify genes potentially under selection. We found high levels of genetic differentiation between populations growing on contaminated and reference soils a few dozen meters apart. In most cases local adaptation was detected, especially in former copper mines. Genome scans identified genes involved in metal stress management as potentially being under selection. This study provides evidence for rapid adaptation to human-induced pollution in alpine plants at remarkably small spatial scales.

Here, using the estuarine fish Scatophagus argus, we demonstrated that primary particle size (20, 60, and 100 nm) and the bidirectional Ag⁰-NPs/dissolved Ag ⁺ interconversion critically governed in vivo toxicity. Our results revealed that Ag exposure induced the most pronounced pro-inflammatory immunotoxicity, characterized by selective enrichment of gut Gram-negative bacteria, lipopolysaccharide (LPS) translocation across a compromised intestinal barrier, and subsequent activation of the TLR/MyD88/NF-κB (Toll-like receptor/myeloid differentiation primary response 88/nuclear factor kappa-B) signaling pathway, an effect most pronounced with 20-nm Ag⁰-NPs and Ag⁺ exposure. Counterintuitively, 20-nm Ag⁰-NPs at an environmentally relevant concentration (10 μg/L) caused significantly higher mortality than equimolar Ag⁺ exposure (15.75 μg/L AgNO₃). This disparity arose because administered Ag⁺ (∼10%) was rapidly sulfidated into low-bioavailability Ag₂S-NPs, constituting an endogenous detoxification mechanism, whereas 20-nm Ag⁰-NPs sustained elevated intracellular and luminal Ag ⁺ levels through continuous dissolution. Prolonged Ag⁰-NPs exposure exacerbated gut microbiota dysbiosis and systemic inflammation. Crucially, fecal microbiota transplantation from exposed donors into germ-free medaka recapitulated elevated serum LPS and enhanced inflammatory response, confirming a causal link between nanoparticle exposure, gut microbiota perturbation, and host immune dysfunction.

Although machine-learning approaches have shown promise in predicting odor characteristics of compounds, existing models primarily rely on molecular physicochemical properties while overlooking the biological interactions between odorants and the human olfactory system. Here, a computational framework integrating molecular descriptors, structural fingerprints, and simulated molecule-olfactory receptor (OR) binding affinities was developed to predict ODTs and odor qualities of volatile compounds. Our framework outperforms conventional physicochemical-based models, with particularly strong discriminative capability for garlic, alliaceous, and sulfurous odors-compound classes commonly associated with odor pollution. The molecular polarity, structural complexity, and OR binding affinity are further identified as prior factors for odor perception.
