| 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. |
