摘　　要：二氧化氮(NO_(2))是重要的室内空气污染物,室外大气来源和室内燃烧源均会影响室内NO_(2)的暴露水平。考虑到高浓度的NO_(2)可能对机体造成不良影响,《室内空气质量标准》(GB/T 18883-2022)的修订中进一步收紧了室内NO_(2)的标准限值,将NO_(2)的1 h平均浓度限值由0.24 mg/m^(3)修订为200μg/m^(3)。本研究对确定该标准限值的相关技术内容进行了分析和讨论,包括室内NO_(2)的来源和暴露水平、健康影响、限值修订依据,并对NO_(2)室内标准的实施进行了展望。Nitrogen dioxide(NO_(2))is an important indoor air pollutant,with both outdoor and indoor sources contributing to indoor NO_(2) exposure levels.Considering the association of high NO_(2) exposure with adverse health effects,the Standards for indoor air quality(GB/T 18883-2022)have been revised to further restrict indoor NO_(2) limit values.The 1-h average concentration limit value for NO_(2) has been reduced from 0.24 mg/m^(3) to 200μg/m^(3).This study analyzed the technical contents related to the determination of the limits of indoor NO_(2) in Standards for Indoor Air Quality(GB/T 18883-2022),including source,exposure level,health effects,and the process and evidence basis for determining the limit value.It also proposed prospects for the direction for the implementation of the indoor NO_(2) standard.
