IMPACTOS DOS BTEX EM ÁREAS URBANAS DA CIDADE DO RIO DE JANEIRO

Most volatile organic compounds (VOC) have adverse effects on human health and the environment and react individually with different velocities and mechanisms to form ozone. The present work determined the concentration of 55 samples of benzene, toluene, ethylbenzene and xylenes (BTEX), an important subgroup of VOC, by active sampling with active carbon cartridge in the areas of Barra da Tijuca, Deodoro and Maracana between the months of December 2014 to September 2015.
