The experiments indicated that overall recoveries from the acid hydrolysis, isolation and derivatization steps will be about 50%. It is apparent that a method even for BaP adducts is not yet complete. The methods described in the paper are provided in detail. Other derivatization techniques are needed that are selective and quantitative, and that will enhance the singal in the mass spectrometer to improve instrument selectivity and sensitivity. In addition to improvements in instrument sensitivity and gas chromatography column performance, there is a great need for procedures for rigorous documentation of organic analytical methods at the picogram level. 12 refs., 2 tabs.
