The objective of this phase of the CAPE-24 program was to develop and validate an analytical method for the analysis of PNA in diesel exhaust particulate. The first year of work included construction of a test engine facility, development of an analytical method for the measurement of PNA, and development of an exhaust tracer injection methodology. The method for the analysis of PNA in diesel exhaust was developed based on the use of stable isotopically labeled PNA as exhaust tracers. A tracer PNA injection method was developed to introduce the tracer PNA to the undiluted exhaust as vapors to insure that the tracer PNA would be subjected to the same temperature and dilution profile as the engine exhaust. Analysis of particulate filter samples indicate that the quantity of engine PNA was much lower than the quantity used to evaluate the analytical method. Although the analytical method was capable of analyzing the engine BaP, the method must still be evaluated for precision and accuracy using levels of PNA equal to the quantities measured in the particulate.
