【摘要】：目的了解手機的污染狀況,研究實用可行的手機消毒方法。方法采用問卷調(diào)查的方式進行手機使用習(xí)慣的調(diào)查,參照《公共場所茶具微生物檢驗方法大腸菌群測定》(GB/T 18204.3-2000)的要求進行大腸菌群的采樣、檢測和評價,依據(jù)消毒技術(shù)規(guī)范(2002)的要求利用酒精擦拭法和紫外線照射法進行消毒效果的檢測和評價。結(jié)果問卷調(diào)查結(jié)果顯示,50份問卷調(diào)查顯示每人每天手機的使用次數(shù)超過20次的人數(shù)占58%,手機使用前后洗手的人數(shù)只占6%,定期對手機進行清洗消毒的人數(shù)只占到2%;污染狀況的調(diào)查顯示大腸菌群的污染率為46%;75%的酒精棉球在對染有金黃色葡萄球菌和大腸桿菌的手機表面擦拭消毒后,試驗的平均殺滅對數(shù)值為5.41和5.54(≥3.00),消毒合格,試驗重復(fù)3次;紫外線手機消毒器,在對染有金黃色葡萄球菌和大腸桿菌的手機表面作用12 min后,試驗的平均殺滅對數(shù)值為3.08和3.10(≥3.00),消毒合格,試驗重復(fù)3次。結(jié)論手機的衛(wèi)生狀況不容忽視,人們對手機的定期清潔和消毒意識薄弱,要養(yǎng)成良好的手機使用習(xí)慣,如經(jīng)常洗手和定期清潔和消毒手機,避免疾病的發(fā)生和流行。
[Abstract]:Objective to understand the status of mobile phone pollution and to study the practical and feasible methods of mobile phone disinfection. The coliform bacteria were sampled, tested and evaluated in accordance with the requirements of "determination of coliform bacteria in tea sets in public places" (GB / T 18204.3-2000). According to the technical specification of disinfection (2002), alcohol wiping method and ultraviolet radiation method were used to detect and evaluate the disinfection effect. Results the results of the questionnaire survey showed that 50 questionnaires showed that the number of mobile phones per person per day exceeded. The number of people who wash their hands before and after the use of mobile phones is only 6, and the number of people who regularly clean and disinfect the phones only accounts for 2. The pollution survey shows that the contamination rate of coliform bacteria is 46% and 75% of the alcohol cotton balls stained with golden yellow. After sterilizing the surfaces of staphylococcal and Escherichia coli cell phones, The average kill logarithm values of the test were 5.41 and 5.54 (鈮，
