Detection and quantitation of PAH-derived DNA adducts requires authentic synthetic standards to act as internal standards and therefore a knowledge of adduct structure. Adduct structure can often be used to provide information on the mechanism of PAH activation that must have occurred. Unfortunately, this is quite challenging since PAH-DNA adducts can be difficult to detect and quantitate since they may be present in only 1 108 nucleotides. State-of-the art methods requiring stable isotope dilution liquid chromatography/multiple reaction monitoring/mass spectrometry (LC/MRM/MS) are necessary to provide sufficient sensitivity to detect these adducts reliably. Additionally, PAH-DNA adducts have different rates of repair and yield different rates of mutation. Thus, each adduct must be assessed so that it can be ranked according to its half-life and miscoding potential. [Pg.133]
