TOXICOLOGY OF DIESEL EMISSIONS
The almost unending complexity of diesel emissions with respect to their chemical constituents has been increasingly revealed, as evermore sensitive and specific procedures have been used for their analysis and identification. However, the character and amount of the complex exhaust mixture is drastically altered by changes in power output, motor speed, engine design and load, and fuel additives. Lack of proper engine maintenance further modifies the nature and amount of emissions. So, despite analytic advances, chemical characterization of diesel emissions is still far more complete, either as to type or amount of the various compounds. Analytic investigators often fail to agree on some classifications of emission components or fail to analyze for the same constituents, leaving comparison gaps. Those uncertainties and unknowns, coupled with potential toxicologic interactions among the exhaust constiuents, make it extremely difficult to make a definitive toxicologic evaluation, or to suggest anything but highly tentative air standards.
