The Study on Exposure Factors to Airborne Mutagens ―The comparison of the mutagenicity between personally exposed and outdoor samples―

 The mutagenicities of both samples obtained by the personal samplers and the sanplers of airborne particulates in outdoors were compared.  A significant correlation between the direct mutagenic activity levels and the number of cigarettes smoked was obtained from the personal data. These results suggest that the sampling and the bioassay technique are important to investigate.
