Abstract: OBJECTIVE:Electric mosquito repellents are widely used therefore their toxicologic effects should be better understood. The purpose of this study was to investigate genoxicity of the repellents in plant cells. METHODS:Plant cells were exposed to various concentrations (25%,50% and 75%) of 3 brands of electric mosquito repellents (BBN,JJ and YB electric mosquito liquid). The micronucleus test was used to monitor genotoxic effects. RESULTS:When the Vicia faba root tip cells were exposed to the three brands of electric mosquito repellents at the 75% concentration,the micronucleus rates were significantly higher than that in the untreated control group (P < 0.05). Under the similar experimental conditions using the garlic root tip cells,only the JJ and YB brands showed significant induction of micronuclei (P < 0.05). Under the similar conditions using the onion root tip cells,both the 50% and 75% concentrations induced significantly higher micronuclei frequencies (P < 0.05). The micronucleus rates in the treated onion root tip cells at the 75% concentration were significantly higher than those of Vicia faba (P < 0.05). The genotoxic effects from the three kinds of electric mosquito repellents showed no significance differences (P > 0.05). CONCLUSION:Three brands of electric mosquito repellents caused genotoxicity to root tip cells of Vicia faba,garlic and onion,and the damage to onion cells was significantly higher than that to Vicia faba. There was no statistical difference in the damage caused by three kinds of electric mosquito repellents.
