目的了解某车用空气净化器对空气中细菌的杀菌功效及毒性。方法据《消毒技术规范》(2002年版),将车用空气净化器置于密闭空间,通过实验观察车用空气净化器对空气自然菌的杀菌效果;将小鼠置于车用空气净化器工作环境中观察小鼠反应。结果车用空气净化器在正常工作情况下,对1m3密闭空间空气消毒0.5h,空气自然菌平均消亡率95.2%;消毒1h,空气自然菌平均消亡率98.1%;20只雌雄各半小鼠置于车用空气净化器工作环境2h后正常饲养,无不良现象。结论该车用空气净化器对密闭小空间内的空气有较好的消毒效果;在无人情况下使用无毒性问题。
Objective To understand the bactericidal efficacy and toxicity of a car air purifier to airborne bacteria. Methods According to the Technical Specifications for Disinfection (2002 Edition), the car air purifier was placed in a confined space, and the bactericidal effect of the car air purifier on natural air bacteria was observed through experiments. The mice were placed in the car air purifier Mouse response was observed in the environment. Results Under normal working conditions, the car air purifier disinfected the air for 1 h in airtight air for 0.5 h and the air natural bacterium averaged 95.2%. The sterilized air for 1 h had an average mortality of natural air bacteria of 98.1%. Twenty female and male mice Car air purifier working environment after 2h normal breeding, no adverse phenomena. Conclusion The vehicle air purifier has a good disinfection effect on the air in a small closed space; it is non-toxic when used unattended.
