In terms of an epidemiologic investigation in Beijing, a higher incidence of lung cancer appears in the population of traffic policemen and workers involved with automobile exhausts which might be a biomarker of the polycyclic aromatic hydrocarbons contamination in their environment. Recently, a purification catalyst containing cheaper metal oxides and rare earth metal oxides for automobile exhaust has been developed in this laboratory. After catalysis the CO, benzene and lower hydrocarbons oxidize completely to form CO{sub 2} and H{sub 2}O. The mark of polycyclic aromatic hydrocarbon (PAH) pollutant penteno(cd)pyrene, can not be found after the catalysis. Other PAH which have been carcinogenicity tested by animals or predicted in terms of Di region theory, were not found in the catalyzed exhaust.
