Mutagenicity and Acute Toxicity Evaluation of 2-Dodecylcyclobutanone
: Mutagenicity and acute toxicity of 2-dodecylcyclobutanone (2-DCB), a unique radiolytic product, were evaluated. Mutagenicity was evaluated by the Ames assay using 5 standard Salmonella tester strains with S9 enzyme activation and 5 concentrations of 2-DCB. Sodium azide (NaN3), fenaminosulf, and2-a...

| 520 | |a : Mutagenicity and acute toxicity of 2-dodecylcyclobutanone (2-DCB), a unique radiolytic product, were evaluated. Mutagenicity was evaluated by the Ames assay using 5 standard Salmonella tester strains with S9 enzyme activation and 5 concentrations of 2-DCB. Sodium azide (NaN3), fenaminosulf, and2-aminofluorene (2-AF) served as positive controls. The Ames assay showed no difference between the 5 concentrations of 2-DCB and the controls, including samples incubated with S9. The results indicate that 2-DCB does not produce point or frameshift mutations in Salmonella and is not activated by S9. Acute toxicity of 2-DCB was evaluated by the Microtox acute toxicity system and compared with cyclohexanone and 2-nonenal (both GRAS additives). The effective concentrations that caused a 50% reduction in light emission by Vibrio fischeri cells (EC50) were; 21.72 6 14.57 ppm for 2-DCB, 37.40 6 0.45 ppm for cyclohexanone, and 1.65 6 0.26 ppm for 2-nonenal. The maximum number of cells affected by 2-DCB was 65% 6 4%, while it reached 90% to 100% for the other 2 compounds. Our results suggest that even though the EC50 for 2-DCB is lower than that for cyclohexanone, it was not toxic enough to decrease light emission of V. fischeri beyond 60% to 70%. These results indicate that the potential risk from 2-DCB, if any, is very low. | ||

Mutagenicity and Acute Toxicity Evaluation of 2-Dodecylcyclobutanone |
| abstract |
: Mutagenicity and acute toxicity of 2-dodecylcyclobutanone (2-DCB), a unique radiolytic product, were evaluated. Mutagenicity was evaluated by the Ames assay using 5 standard Salmonella tester strains with S9 enzyme activation and 5 concentrations of 2-DCB. Sodium azide (NaN3), fenaminosulf, and2-aminofluorene (2-AF) served as positive controls. The Ames assay showed no difference between the 5 concentrations of 2-DCB and the controls, including samples incubated with S9. The results indicate that 2-DCB does not produce point or frameshift mutations in Salmonella and is not activated by S9. Acute toxicity of 2-DCB was evaluated by the Microtox acute toxicity system and compared with cyclohexanone and 2-nonenal (both GRAS additives). The effective concentrations that caused a 50% reduction in light emission by Vibrio fischeri cells (EC50) were; 21.72 6 14.57 ppm for 2-DCB, 37.40 6 0.45 ppm for cyclohexanone, and 1.65 6 0.26 ppm for 2-nonenal. The maximum number of cells affected by 2-DCB was 65% 6 4%, while it reached 90% to 100% for the other 2 compounds. Our results suggest that even though the EC50 for 2-DCB is lower than that for cyclohexanone, it was not toxic enough to decrease light emission of V. fischeri beyond 60% to 70%. These results indicate that the potential risk from 2-DCB, if any, is very low. |
