Determination of polynuclear aromatic hydrocarbons present in asphaltenes from Mexican oil. A possible environmental risk.
A supercritical fluid extraction and HPLC analysis of the asphaltenes derived from Mexican oil was performed. The aim was to identify potentially mutagenic polynuclear aromatic hydrocarbons present in asphaltenes, since roof waterproofing applications in this country present a significant exposure to hot asphaltene vapors that might conceivably carry such toxic hydrocarbons and therefore pose a health hazard to the workers who apply molten asphaltenes.
