摘　　要：细菌总数作为室内空气的重要污染物一直备受关注,《室内空气质量标准》(GB/T 18883-2022)将细菌总数标准限值收紧至1500 CFU/m^(3)。本文对室内空气中细菌总数标准限值确定过程中相关的技术内容进行了梳理,包括细菌总数在空气中的分布水平、暴露情况、健康效应和标准限值的确定等,并对未来室内空气细菌总数限值的制修订方向提出了展望。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^(3) 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.
