The mutagenicity of three isomers of nitro-6H-dibenzo[b,d]pyran-6-one (NDBP), 2-NDBP, 3-NDBP and 4-NDBP, was characterized in the plate-incorporation (PI) and microsuspension (MS) assays using Salmonella typhimurium tester strains in the presence or absence of S9 mix. In both assays, all of the NDBPs showed mutagenicity in every strain. In the absence of S9 mix, TA98 was the strain most sensitive...
