Introduction: Phytoremediation is one of the available techniques for removing the volatile organic compound from the air. Benzene and toluene are volatile organic compounds that exist in many occupational environments. Plants are able to reduce benzene and toluene in the air and the use of plants is a simple and consistent solution for the nature to reduce these compositions in the air and imp...

tire manufacturing industry has a history of more than half a century in iran, where 14 thousand workers are employed. the old and semi-automated processes equipment, backward technology, and raw materials impurity lead to significant exposures to occupational carcinogens such as benzene. this study was to assessment of benzene exposures and evaluation the resulting cancer risk in two tire-manu...

The current study aimed to examine the overall feasibility of the use of copper oxide nanoparticles (CuO-NPs) as a catalyst in ozonation process for the removal of benzene from aqueous solutions under experimental conditions. This experimental study was conducted on a laboratory scale reactor in a semi-batch mode. The effect of critical operating parameters such factors as pH, concentration of ...

Abstract Background: To establish a method for determination of in-cabin benzene and evaluate the occupational exposure, a cross-sectional study was conducted. Methods: In this descriptive study, 30 taxi-cabs were selected and the concentrations of benzene was measured in stopping and driving conditions using solid phase microinstruction (SPME) method. Results: The overall average conc...
