The vinyl monomer acrylamide (AA) was studied for its activity in a range of genotoxicity tests, including the Salmonella/microsome test, the fluctuation test using Klebsiella pneumoniae, the test for gene mutations at the TK and HPRT loci in L5178Y mouse lymphoma cells, tests for chromosomal aberrations and SCEs in V79 Chinese hamster cells, the sex-linked recessive lethal (SLRL) and somatic mutation and recombination (SMART) assays in Drosophila melanogaster and the mouse bone marrow micronucleus assay. AA showed genotoxic activity in most systems. The bacterial tests did not respond, in compliance with literature data; also in the Drosophila SLRL test, no significant increase in mutation rate was observed.

Methyl bromide is commonly used as a soil fumigant in greenhouses. In the framework of a toxicological evaluation, it was tested for possible genotoxic properties in two bacterial test systems (the fluctuation test using Klebsiella pneumoniae and the plate test using Salmonella typhimurium TA100 and TA98), two systems using mammalian cells in vitro (forward mutations at the TK and HPRT loci in L5178Y mouse lymphoma cells and unscheduled DNA synthesis in primary rat-liver cells) and in the sex-linked recessive lethal test using Drosophila melanogaster. Methyl bromide was active in all tests except the DNA-repair assay. The results indicate a relatively low mutagenic efficiency of the compound, as expected from its alkylating properties.
