| Abstract: | 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.The orders of sensitivity for six strains to both of 1|NP and 1,6|DNP is YG1024,YG1021,TA98,YG1026,YG1029,TA100,but it is not for 2|NF.The results of the joint mutagenicity of the mixtures of 1|NP and each of NO-2|PAHs showed that 2|NF and 1,6|DNP strengthened the mutagenicity of 1|NP,but inhibited by every PAHs. |

| Keywords: | NP NO 2|PAHs ames test joint mutagenicity sensitivity |
