The mutagenic potential of three alkyl 2-cyanoacrylate adhesives, three commercial alkyl 2-cyanoacrylate adhesives and three methyl 2-cyano-3-phenylacrylates, was assessed using the Salmonella/microsome mutagenicity assay. Compounds were tested with and without Aroclor 1254-induced rat-liver homogenate (S9 mix).The methyl 2-cyanoacrylate adhesives were mutagenic in the standard plate test with S. typhimurium strain TA100 with and without S9 activation.Methyl 2-cyano-3-(2-bromophenyl)acrylate revealed a direct mutagenic action to S. typhimurium strain TA1535.The compounds most toxic towards the bacterium S. typhimurium, were the methyl 2-cyanoacrylate adhesives (>500 μg/plate).All alkyl 2-cyanoacrylate adhesives were tested in a modified spot test for volatile compounds with tester strain TA100.Mutagenic and toxic effects were observed with the three methyl 2-cyanoacrylate adhesives.It can be concluded from the results that the bacterial toxicity and mutagenicity of methyl 2-cyanoacrylate adhesives may be due to the methyl 2-cyanoacrylate monomer.
