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 ...

background: nanotechnology is a new approach that has been lionized in recent years. one of its applications is its consumption as an absorbent. in this study, the single-wall carbon nanotubes (swcnts) were used as an absorbent for sampling benzene in the air. materials and methods: for this study, swcnts manufactured by iran and skc’s activated charcoal were used for sampling benzene vapors. p...

background: volatile organic compounds (vocs) are among the main air pollutants which have destructive effects on the environment and human health. considering the carcinogenic effects of some of these compounds including benzene, how to control and limit them is considered an important issue in environmental research. the aim of this study was to evaluate the use of the combined ultraviolet (u...

this paper focuses on the effects of the addition of an ionic liquid, 1-allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([abim]tfsi), which has a high affinity for benzene, into the poly(vinyl chloride) (pvc) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. when aqueous solutions of 100～500 ppm benzene were permeated ...
