ABSTRACT
This article discusses the concentrations of volatile aromatic hydrocarbons (VAC) from a tunnel carrying light-duty vehicles in Rio de Janeiro, Brazil. According to the authors, nearly three-quarters of all vehicles in Brazil use gasohol in their vehicles. This study used a gas chromatograph-mass spectrometer to measure the VAC emissions and the ozone forming potential of these gases coming out of the tunnel was determined. They found that most of the emissions consisted of benzene, toluene, ethylbenzene, and xylene (BTEX) but that the major contributors to ozone formation were the alkylbenzenes.
