Volatile organic compounds (VOCs), the precursors of ozone and fine particulate matter, are one atmospheric pollutants harmful to human health. The emission characteristics VOCs in Anyang, a typical industrial city Central Plains China, unclear. To determine level composition local VOCs, this study conducted on-site sampling 20 factories eight key industries. A total 105 VOC species seven categories were observed. concentration emitted from industries order large small was as follows: packaging printing > pharmaceutical paint manufacturing coating chemical industry metal smelting furniture textile dyeing. In addition coating, their corresponding formation potential organized emissions (1.44–87.64, 1.52–181.61 mg/m3) higher than those unorganized (0.38–24.17, 0.38–125.55 mg/m3). concentrated central, south-central, south-eastern parts city, mainly printing, pharmaceutical, paint, (4.55 × 10−3) (1.66 at high risk carcinogenesis, while (3.61 10−4) moderate carcinogenesis.

Waste disposal in landfills remains a global concern. Despite technological developments, landfill leachate poses hazard to ecosystems and human health since they act as secondary reservoir for legacy emerging pollutants. This study provides systematic scientometric review of the nature toxicity pollutants generated by means assessing their potential risks. Regarding health, unregulated waste pathogens are leading causes diseases reported local populations. Both vitro vivo approaches have been employed ecotoxicological risk assessment leachate, with model organisms ranging from bacteria birds. These studies demonstrate wide range toxic effects that reflect complex composition geographical variations climate, resource availability, management practices. Based on bioassay (and other) evidence, categories persistent chemicals most concern include brominated flame retardants, per- polyfluorinated chemicals, pharmaceuticals, alkyl phenol ethoxylates. However, more general literature microplastic suggests these particles might also be problematic leachate. Various mitigation strategies identified, focussing improving design or treatment, developing alternative methods reducing volume through recycling using sustainable materials.

Abstract Methanol, a toxic volatile compound, poses significant threats to human health and the environment. Traditional methanol sensors require high operating temperatures, exhibit poor selectivity, have limited long-term stability, which restricts their application in portable monitoring devices. This study proposes flexible chemoresistive gas sensor based on laser-induced graphene (LIG) electrodes cobalt phthalocyanine (CoPc)- multi-walled carbon nanotubes (MWCNT) composite. Experimental results demonstrate that achieves an excellent sensitivity of 0.589 Ω/ppm low limit detection 165 ppb over wide range 10–1000 ppm, covering international exposure limits. Moreover, exhibits selectivity towards comparison other interfering organic compounds (e.g., ethanol, isopropanol, acetone). Under 500 ppm methanol, response time (τ45) is 5 s, recovery (τ85) 108 hysteresis only 2.77%. The synergistic effects three-dimensional porous structure LIG, conductivity MWCNT, electron transfer characteristics between CoPc molecules collectively optimize charge transport adsorption efficiency, enabling achieve sensing performance at room temperature. Additionally, it shows also outstanding stability 30 days, with degradation rate less than 4.25%. These attributes indicate LIG-CoPc/MWCNT holds great potential industrial safety environmental applications while providing critical technological support for development high-performance, low-power sensors.
