Chemical emissions from building materials may significantly impact indoor air quality and potentially human health, since individuals spend most of their time indoors. With rising global temperatures more frequent heatwaves, materials’ resilience becomes crucial for structural integrity. However, the effects temperature rise on material are not systematically studied. This study investigates effect a moderate volatile organic compound (VOC) aldehyde eighteen commonly used materials, such as engineered hardwood, nylon carpet, terrazzo flooring, acoustic tile, at two elevated yet realistic points. The chemical were collected using micro-chamber setup analyzed thermal desorption/gas chromatography/mass spectrometry high-performance liquid chromatography. results showed that 78% tested demonstrated increased higher temperatures. Wood-flooring statistically significant increases in formaldehyde temperatures, which could be associated with health risks. Eight particularly those large surface area applications, half these labeled “low-VOC”. These findings inform updating standards third-party certification respect to variation when assessing emissions. research aims provide comprehensive understanding VOC emerging environmental conditions due extreme heat climate scenarios.

Microbial remediation is an eco-friendly and cost-effective method for treating organic-contaminated soil, essential sustainable land use due to its minimal secondary pollution operational simplicity. However, during the degradation of polycyclic aromatic hydrocarbons (PAHs), formation polar or toxic intermediate metabolites can lead unpredictable ecotoxicological impacts. In this study, we investigated effects microbial soils on wheat seedling growth physiology, evaluated soil ecotoxicity throughout process. The results showed that concentrations benzo[a]anthracene (BaA) benzo[a]pyrene (BaP) decreased by 70.4% 49.9%, respectively, following degradation, with process a second-order kinetic model. Despite reduction in pollutants, toxicity increased from days 10 20, peaked day then gradually decreased, but it remained elevated Increased inhibited seed germination, growth, chlorophyll content, induced oxidative stress, suppressed enzyme activity. Gas chromatography–mass spectrometry (GC-MS) analysis identified as primary contributors enhanced ecotoxicity. Wheat germination potential, plant height, root length, superoxide dismutase (SOD) catalase (CAT) activity roots effectively indicate These parameters facilitate optimization strategies ensure restored functionality long-term ecological sustainability.

The synthetic phenolic antioxidant 2,4-di-tert-butylphenol (2,4-DTBP) is an emergent contaminant and can disrupt the delicate balance of aquatic ecosystems. This study aimed to investigate 2,4-DTBP-induced hepatotoxicity in common carp underlying mechanisms involved. Sixty were divided into four groups exposed 0 mg/L, 0.01 0.1 mg/L or 1 2,4-DTBP for 30 days. Here, we first demonstrated that exposure caused liver damage, manifested as hepatocyte nuclear pyknosis, inflammatory cell infiltration apoptosis. Moreover, induced hepatic reactive oxygen species (ROS) overload disrupted capacity, indicated by reduced activity enzymes superoxide dismutase (SOD), catalase (CAT) glutathione peroxidase (GSH-Px). In addition, transmission electron microscopy revealed autophagosome accumulation carp. Western blot analysis further significantly decreased protein levels mTOR increased LC3II/LC3I ratio. Furthermore, inhibited lysozyme (LZM) alkaline phosphatase (AKP) activity; immunoglobulin M (IgM), complement 3 (C3), 4 (C4) serum; mRNA proinflammatory cytokines (NF-κB, TNF-α, IL-1β IL-6); three types proliferator-activated receptors (PPARs) (α, β/δ γ). Molecular docking directly binds internal active pocket PPARs. Overall, concluded systems could induce regulating autophagy controlling responses. present provides new insights mechanism organisms furthers our understanding effects on public health ecotoxicology.
