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.
