The total bacteria count has been attracting attention as an important pollutant in indoor air, and its standard limit was tightened to 1500 CFU/m in "Standards for indoor air quality (GB/T 18883-2022).The technical contents related to the determination of the indoor air standard limits for total bacteria count were analyzed and studied, including the environmental existence level, exposure status, the health effects and the derivation of the limit value. It also proposed prospects for the future development and revision of quality standards for total bacteria count in indoor air.
室内空气中的细菌总数作为一种重要污染物一直备受关注，其标准限值在《室内空气质量标准（GB/T 18883-2022）》中收紧至1500 CFU/m³。对室内空气细菌总数标准限值测定相关技术内容进行了分析研究，包括环境存在水平、暴露状况、健康影响及限值推导等。还对室内空气细菌总数质量标准的未来发展和修订提出了展望。
