TEST OF SOME METHODS FOR ANALYSES OF UNREGULATED POLLUTANTS

A method for testing the direct mutagenic effect of true gas phase automotive emissions on line has been tried. The method is only sensitive enough for test times of about 1 hour when, however, toxicity starts to be noticeable. The method is not recommended in its present form, but could possible be developed in a research project in the future. Phenol and cresols have been analysed by two different laboratories in the exhaust gases from a heavy duty vehicle. The results are congruent. Analyses of the phenol and cresol emissions from gasoline fuelled vehicles with and without catalyst correspond well with results published by for example Volkswagen. The use of a pure isoparaffine fuel result in a 10-20 times lower phenol and cresol emission compared to reference gasoline with 35% aromatic content. Phenols and cresols have a considerably "carry over" between tests and new configurations of exhaust systems as well as modified test procedure are proposed.
