Abstract

It is intended to study the contribution of sugarcane burning to atmospheric contamination through the emission of PAHs and nitro-PAHs and evaluate the occupational exposure of sugarcane cutters to these compounds by means of the determination of these emissions in the particulate matter in suspension and inhablable and through monitoring of the biological indicator excreted in the urine as 1-hydroxypyrene. The samples of IPM will be collected through Hi-vol samplers in the city and in the canefields, throughout the year, to obtain a seasonal view of the contamination studied. The IPM will be collected in the respiratory zone of the sugarcane cutters and from these same workers urine will be collected for the determination of the biological indicator. (AU)
