Development of analytical capabilities to evaluate unregulated emissions are discussed. The sampling and analysis methods along with some problem areas are included. Results obtained on three heavy-duty diesel engines are reported. Emphasis was placed on analysis of the particulate fraction including the solvent extractable material. Preliminary experiments suggest appreciable quantities of organic extract and BaP pass through the primary filter. Other species analyzed to obtain a baseline for emission reduction research included aldehydes, sulfates, sulfur dioxide, ammonia, hydrogen sulfide, and hydrogen cyanide. Of primary concern is the proper assessment of the results.
