ANALYTICAL PROCEDURES FOR CHARACTERIZING UNREGULATED POLLUTANT EMISSIONS FROM MOTOR VEHICLES
Analytical procedures are described that may be used to assess motor vehicle emission rates of several unregulated pollutants including aldehydes, organic amines, sulfur dioxide, nitrous oxide, several individual hydrocarbons including benzene, hydrogen sulfide, total cyanide, organic sulfides, nickel carbonyl, ammonia, sulfate, and N-nitrosodimethylamine (sampling conditions only). A series of validation experiments involving motor vehicle exhaust with injects of known quantities of the compounds of interest and the Constant Volume Sampling system commonly used in emissions certification are described for several of the analytical procedures. The Clean Air Act as emended August 1977 requires in section 202(a) 4 that unregulated pollutants emitted from motor vehicles be measured to assure that no unreasonable risk to public health and welfare exists.
