摘要: 目的:电热蚊香液使用广泛,本研究旨在探讨其对植物的遗传损伤效应。方法:以蚕豆、大蒜和洋葱为实验材料,采用植物根尖细胞微核试验,测定在不同浓度(25%、50%和75%)的3种品牌(BBN、JJ和YB)蚊香液处理下,植物根尖细胞的微核率。结果:随着3种蚊香液浓度的增加,植物根尖细胞微核率也随之增加。75%的BBN、JJ和YB蚊香液分别作用于蚕豆根尖细胞时,细胞微核率均显著高于对照组(P < 0.05);75%的JJ和YB蚊香液分别作用于大蒜根尖细胞时,微核率较对照组差异显著(P < 0.05);50%和75%的3种蚊香液作用于洋葱根尖细胞时,微核率高于对照组(P < 0.05);75%的JJ和YB蚊香液处理组洋葱根尖的细胞微核率明显高于蚕豆(P < 0.05);3种品牌蚊香液对植物根尖细胞遗传损伤效应的差异无统计学意义(P > 0.05)。结论:在本实验条件下,蚊香液达到一定浓度时均对蚕豆、大蒜和洋葱根尖细胞造成遗传损伤,高浓度蚊香液对洋葱的遗传损伤显著高于蚕豆,不同品牌蚊香液对植物产生的损伤程度无明显差异。

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.
