环境卫生学监测细菌菌落总数换算简表的应用研究

Study on the Application of the Simplified Conversion Table for Count of Total Bacterial Colonies in Environmental Hygienic Monitoring

目的免去以往环境卫生学监测中对单位空气和单位面积细菌菌落总数繁琐的换算过程,提高监测工作效率,保证监测结果计算的准确性。方法针对不同监测对象,依据相应的公式、方法和相关条件,经反复计算和实践编制出包括空气、物品和环境表面、皮肤、粘膜、手等监测项目的《环境卫生学监测细菌菌落总数换算简表》。结果该《环境卫生学监测细菌菌落总数换算简表》完全可替代环境卫生学监测中对单位空气和单位面积细菌菌落总数的换算过程。只用平板或基条上的细菌菌落总数即可在表中直接查到每m3空气或每cm2面积所含的细菌菌落总数。结论该《环境卫生学监测细菌菌落总数换算简表》计算依据规范,可靠,数据精确;使用方便,换算快捷;实用性强,并具有无限的扩展性。不仅适合医院环境卫生学监测细菌菌落总数的换算,也适用于卫生防疫、制药业和有关科研等单位。使用该换算表可明显提高监测工作效率,并保证数据换算的准确性。

Objective To avoid the complex conversion process of total count of bacterial colonies per unit volume of air and per unit area in environmental hygienic monitoring,to raise the efficiency and ensure the accuracy of the monitoring.Methods According to related calculation formulas,methods and conditions,based on the repeated calculation and numerous practice of monitoring data analysis,The Simplified Conversion Table for Total Count of Bacterial Colonies in Environmental Hygienic Monitoring,which was applicable to the bacterial monitoring of different monitored objects including air,articles,object surface in environment,skin,mucous and hands was drawn up.Results The complex conversion process of total count of bac-terial colonies per unit volume of air and per unit area could be replaced by this table.The total count of bacterial colonies per unit volume of air and per unit area on the plates could be derived from this table.Conclusion The simplified conversion table was reliable,accurate,simple to use,practical and expandable.It was suitable not only for the sanitary bacterial monitoring in hospital,in pharmaceutical industry and scientific research institutes,but also for epidemic prevention.The monitoring efficiency could be improved by using this table obviously.
