The Salmonella/microsome mutagenicity assay (Ames test) was based on the premise that bacterial assay systems provide an efficient way to detect the mutagenic activities of airborne mutagens and carcinogens. In routine work for detecting the mutagenic activities of airborne mutagens and carcinogens using the Ames test, the pretreatment of tremendous amounts of samples and the counting of revertant colonies can be labor‐intensive and time‐consuming.
