Ccording to the Ames test specification, TA97, TA98, TA100 and TA102 strains were used and the ammounts of 3 kinds of dust and their mixture with benzopyrene were 5000, 500, 50 and 5 μg/plate, respectively. The number of colony was counted after culturing for 48 h at 37 ℃. SCE test was performed with peripheral blood lymphocytes of healthy men. The ammounts of 3 kinds of dust and their mixture with benzopyrene were 500, 50 and 5 μg/plate, respectively. The chromosome specimen slide was made after culture 72 h at 37 ℃ and the frequency of SCE was counted. There were triplicate plates in each group and negative and positive controls were set up in Ames and SCE tests.

The mutagenicities of 1|nitropyrene(1|NP), 2|nitrofluorene(2|NF), 1, 6|dinitropyrene(1, 6|DNP), and five PAHs on Salmonella typhimurium TA98, TA100, YG1021, YG1024, YG1026, YG1029 were studied. The results showed that 1, 6|DNP is the most potent mutagen, next is 1|NP and the last is 2|NF; However, the mutagenicities of all PAHs tested are negative.
