Ozônio troposférico e compostos orgânicos voláteis em região impactada pela agroindústria canavieira

The purpose of this study was to evaluate the concentrations of tropospheric ozone and VOCs under the sugarcane agro-industry emissions in urban and rural areas of Araraquara, SP. The sampling was performed using active and passive air samplers during the sugarcane harvest and in the period between harvests in 2011 and 2012. Also, canisters were undertaken in 3 situations: during and after the burning of the cane plantations and in an urban area. Instrumental analysis was carried out using gas and ion chromatography. The highest VOC concentrations were found for toluene and d-limonene at the urban area and for ethene during the burning of sugarcane. Although sugarcane industry is an important emission source of ozone precursors, in this study the tropospheric ozone levels do not increased significantly under sugarcane agro-industry emissions.
