Abstract
The mutagenic activities of 17 reagents used in water test were tested using Salmonella typhimurium TA 100 and TA 98. According to the results, five compounds of 17 tested reagents, such as Sodium azide, α-Naphythylamine, p-Dimethylaminobenzylidenerhodanine, o-Tolidine and 8-Hydroxyquinoline were found to be mutagenic on S. typhimurium TA 100, TA 98 or both. Therefore, we must be careful with use of these five reagents and, as soon as possible, make a new method of water test not using these mutagenic compounds.
