The Salmonella mutagenicity assay: the stethoscope of genetic toxicology for the 21st century.

abstract：:Thirty compounds of various chemical classes were investigated for mutagenicity in a collaborative study (three laboratories) using Salmonella typhimurium TA102. With five compounds, hydrazine sulfate, phenylhydrazine, hydralazine, glutardialdehyde, and glyoxal, mutagenicity was detected by all laboratories. Formaldeh...
