Abstract
In Brazil the policy for disposing industrial sludge is changing from an emphasis on using controlled landfills to other treatment or coprocessing methods however the monitoring of organic pollutants is not mandatory The present study evaluated two general screening methods for organic pollutants in sludge generated in an automotive industrial complex in southern Brazil The screening was performed using Soxhlet and sonication extractions and Gas Chromatograph coupled with Quadrupole Mass Spectrometry GC/qMS It was concluded that both techniques were effective and that most of the compounds identified were alkanes phenols and esters Important pollutants were detected in the sludge which confirms the necessity of monitoring this type of residue
