In the rapidly evolving domain of vapor intrusion (VI) assessments, traditional methodologies encompass detailed groundwater and soil sampling coupled with comprehensive laboratory measurements. These models, blending empirical data, theoretical equations, site-specific parameters, evaluate VI risks by considering a spectrum influential factors, from volatile organic compounds (VOC) concentrations in to nuanced attributes. However, challenge variability, influenced dynamic ambient conditions intricate properties, remains. Our study presents an advanced on-site gas sensing station geared towards real-time VOC flux monitoring, enriched array sensors, spearheaded reliable PID sensor for detection. Integrating this system machine learning, we developed predictive notably random forest regression, which boasts R-squared value exceeding 79 % mean relative error near 0.25, affirming its capability predict trichloroethylene (TCE) accurately. By synergizing monitoring insights, our methodology refines risk equipping communities proactive, informed decision-making tools bolstering environmental safety. Implementing these models can simplify residents, reducing dependence on specialized systems. Once proven effective, there's potential repurpose stations other VI-prone regions, expanding their reach benefit. The model leverage weather forecasting data provide alerts future events.

Abstract In this paper, we analyze the performance of diffusion-based gas distribution in antiresonant hollow-core fiber-based absorption cells. Performed theoretical analysis was based on Fick’s second law using OpenFOAM® software and finite volume method (FVM), followed by an experimental verification obtained simulations. The diffusion time tested for a 1.25 m long fiber, with laser-micromachined microchannels. Full correlation between microchannel count, position, separation rate at which cell filled target presented. Experimental results showed that proper configuration, purely-diffusion-based exchange fiber could be reduced from 6 h, down to 330 s. Obtained correlated simulations, giving perspective development implementation novel miniaturized passively cells compact laser spectrometers.

Abstract Prolonged exposure to alcohol vapors can have detrimental effects on human health, potentially leading eye irritation, dizziness, and in some cases, damage the nervous system. The present article aims provide a comprehensive understanding synthesis characterization of zinc ferrite (ZnFe 2 O 4 ) nanoparticles, as well their interactions with range vapors, including methanol, ethanol, n‐propanol, isopropanol. These alcohols differ molecular weight, boiling points, diffusivity, other properties. study reveals semiconducting ZnFe nanoparticulate sensor‘s capability for reversible, repeatable, sensitive detection vapors. sensor exhibits highest response ethanol within operating temperature (225–300 °C). An attempt is made establish correlation between properties target analytes observed sensing signals. Additionally, conductance transients under studied are modeled based Langmuir‐Hinshelwood adsorption mechanism. characteristic time constants obtained from this modeling justified respect analytes.
