Benzene, Toluene, Ethyl Benzene and Xylene are volatile organic compounds (VOCs) with approximately similar physical and chemical characteristics. Benzene and Ethyl-benzene are known carcinogen as well as they affect the circulatory, nervous, and reproductive and respiratory systems. Toluene and Xylene also damage the nervous and reproductive systems. The main purpose of this study is to determ...

Background and aims: Volatile organic compounds (VOCs) are of environmental concern because of their adverse effects on human health. VOCs contain a large group of substances like toluene. Today application of catalytic beds is one the ways to control these kinds of emissions. In this study photocatalytic removal of toluene vapour by titanium dioxide nanoparticles immobilized on ZSM-5 zeolite h...

Previous studies have shown that toluene, which is commonly abused, depresses neuronal activity and causes behavioral effects in both animals and man similar to those observed for ethanol. In this study, the oocyte expression system was used to test the hypothesis that toluene, like ethanol, inhibits the function of ionotropic glutamate receptors. Oocytes were injected with mRNA for specific N-...

We demonstrate two simple methods to fabricate QD-stabilized toluene microdroplets in water as whispering gallery mode microscale resonators in an all-liquid phase. The toluene microdroplets show size-dependently high Q-factors up to 5100 resulting from the stable QD-loaded microdroplets. The highly QD-stabilized toluene microdroplet resonators in the all-liquid phase would be promising for mul...

The effects of experimental exposure to toluene (100 ppm), xylene (100 ppm) and their mixture (50 ppm of toluene and 50 ppm of xylene) on CNS functions were studied in 10 male volunteers aged 22-35. Changes in CNS functions were measured by means of nine psychological tests. Acute exposure to xylene produced the most adverse effect on simple reaction time SRT and choice reaction time ChRT. Expo...

We developed a cognitive-pharmacokinetic computational (CPC) model to understand how pharmacoactive substances, such as caffeine and toluene, modulate cognition. In this integrated model, dynamic physiological mechanisms are simulated to predict concentrations of the solvent toluene in the brain, which modulates specific cognitive systems in a doseresponse fashion over multiple hours. We used o...

Silicon (Si) has not been considered as an essential nutrient for plant growth however, it has been shown that supplying crops with adequate Si can improve environmental stress tolerance. On the other hand, exposure to toluene, as a hazardous organic pollutant widely found in the water resources, is an environmental stress for plants growing around many industries. The aim of this nutrient solu...
