Whole diesel exhaust has recently been classified as a portable carcinogen, and particulate exhaust known to contain mutagenic and carcinogenic chemicals, has clearly shown to be mutagenic in several genotoxicity studies. The goal of this study was to determine whether, and to what extent, the installation of some exhaust aftertreatment devices on two light-duty diesel engines (1930 cc and 2500 cc) EGR-valve equipped may reduce mutagenic activity associated to particles collected during both USA and European driving cycles. The preliminary results point out the usefulness of mutagenicity tests in the research of even new more efficient automotive emission aftertreatment devices. The aim of this investigation is to determine whether, and to what range, the use of some new aftertreatment devices on light-duty diesel engines could reduce the particle-associated genotoxic potential of diesel emissions. 24 refs., 3 figs., 1 tab.
