background: toluene is a harmful substance still being used as a solvent and catalyst in many industries that can increase the level of urinary hippuric acid (uha). this study was designed to examine the level of toluene and uha among workers of industrial site in seven companies in sidoarjo, indonesia and to analyze the risk factors for abnormal uha. methods: this study was an analytical cross...

the catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. the dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. it has been suggested that liquid phase oxidation of tolue...

exposure to toluene can be associate with genotoxicity, neurological dysfunction, reproductive toxicity, and etc. biomonitoring of hippuric acid (ha) is used for a long time as an occupational exposure index to toluene. the aim of this study was to explore efficiency of ha as a biomarker of exposure to low level of toluene for iranian petroleum depot workers in 2011. personal monitoring to tolu...

Composites of polyaniline and carbon nanotube (CNT) were prepared by in-situ chemical polymerization method using various aniline concentrations in the initial polymerization solution with p-toluene sulfonic acid (PTS) as secondary dopant and mechanical mixing of the PANI and CNT using different weight ratios of PANI and CNTs. The structural characterizations of the composites were done by Four...

With the surge of interest in miniaturized implanted medical devices (IMDs), implantable power sources with small dimensions and biocompatibility are in high demand. Implanted battery/supercapacitor devices are commonly packaged within a case that occupies a large volume, making miniaturization difficult. In this study, we demonstrate a polymer electrolyte-enabled biocompatible magnesium-air ba...

Available synthetic antioxidants such as butylated hydroxyl anisole, toluene, propyl gallate, and ascorbic acid exhibit several side effects. To curb these effects, more effective, less toxic, cost-effective drugs are required. Therefore, this study aims to screen evaluate the antioxidant well anti-inflammatory antidiabetic potential of Houttuynia cordata collected from Mairang village, West Kh...
