Polycyclic Aromatic Hydrocarbons are ubiquitous pollutants that usually present carinogenic and mutagenic effects. Several organisms are able to metabolize them quickly, and therefore becoming very important the development of analytical techniques for their metabolites determination. The chemical analyses of 1-hydroxipyrene is one of the first steps for evaluation of environmental assessment by PAH exposure. Pyrene is one of the principal compounds of this xenobiotic class and 1-hydroxipyrene is yours major metabolite. This study presents a method for qualitative analysis of 1-hydroxipirene. Tests were performed due to allow the use of a methodology for routine analysis in biological samples. The chosen method included acid hydrolysis followed of liquid-liquid extraction to obtain 1- hydroxipyrene. Gel permeation chromatography (GPC) was applied as a lipid separation method, and then liquid chromatography of opened column. As long as the 1- hydroxipyrene is a low volatile compound, it was included one step of derivatization with BSTFA followed by gas chromatography/mass spectrometer (GC/MS) analysis.
