Evaluation of Volatile Organic Compounds Levels inside Taxis Passing through Main Streets of Tehran

International Journal of Occupational Hygiene, 2015
Air quality inside commuting vehicles has seldom been evaluated in Iran. Accordingly, this study investigates the levels of benzene, toluene, ethylbenzene and xylene (BTEX) during workdays characterized by heavy traffic inside taxis in Tehran- Iran ...

Tunable Plasma‐Polymerized Organosilicon Films for Toluene Sorption

Plasma Processes and Polymers, Volume 22, Issue 9, September 2025.
This study demonstrates that plasma conditions during PECVD tune organosilicon film structure and toluene sensing, with rubbery films offering high sensitivity, strong selectivity for toluene over water, and excellent reversibility. These insights enable the tailored design of advanced materials for sensitive, selective detection of VOC contaminants in

Collapsible Kernel Machine Regression for Exposomic Analyses

Statistics in Medicine, Volume 44, Issue 20-22, September 2025.
ABSTRACT An important goal of environmental epidemiology is to quantify the complex health effects posed by a wide array of environmental exposures. In studies of a small number of exposures, flexible models like Bayesian kernel machine regression (BKMR) are appealing because they allow for non‐linear and non‐additive associations among exposures ...

Assessment of the impact of benzene, toluene, ethylbenzene, and xylene (BTEX) on soil microbial population in selected areas of Port Harcourt City, Nigeria

Scientific African
Human activities are on the rise in these areas and consequently, the discharge of BTEX to the environment is on the rise. Benzene, toluene, ethylbenzene, and xylenes (BTEX), are known to cause cancer and mutagenesis.

Field‐Scale qPCR Data to Estimate Rate Constants for Toluene Biodegradation in Groundwater

Groundwater Monitoring &Remediation, Volume 45, Issue 4, Page 42-50, Fall 2025.
Abstract Biodegradation of petroleum hydrocarbons in groundwater occurs naturally and can be enhanced to support contaminated site management and remediation. Molecular biological tools can be used to assess the occurrence of biodegradation and monitor bioremediation efforts; however, the use of specific genes (i.e., biomarkers) to identify the rate ...

BTEX emissions from flex fuel motorcycles

Atmospheric Pollution Research, 2017
Abstract Comparative studies were developed with regard to the criteria emissions of THC - total hydrocarbons, CO - carbon monoxide and NO x - nitrogen oxides, and BTEX (benzene, toluene, ethyl benzene and xylenes). Three four-stroke motorcycles were fuelled with E22 fuel (gasoline with 22% of ethanol).

Study of the volatile organic compounds (VOCs( in the exhaust air from low heat sterilizer devices of four hospitals in Tehran

Salāmat-i kār-i Īrān, 2014
Background and aims: Application of low heat devices was increased for infectious waste sterilizing in many hospitals in Iran. Studies have shown that the generation of volatile organic compounds (VOCs) and hazardous materials is most probable in the ...

Zeolite/iron oxide composite as sorbent for magnetic solid-phase extraction of benzene, toluene, ethylbenzene and xylenes from water samples prior to gas chromatography-mass spectrometry [PDF]

, 2016
This study reports a new composite based on ZSM-5 zeolite decorated with iron oxide magnetic nanoparticles as a valuable sorbent for magnetic solid-phase extraction (MSPE). A proposal is made to determine benzene, toluene, ethylbenzene and xylenes (BTEX)
