[Study on formulation and revision of standard limit for formaldehyde in the "Standards for indoor air quality（GB/T 18883-2022）" in China].

Formaldehyde, as an important pollutant in indoor air, has always been of great concern. In the newly issued "Standards for indoor air quality (GB/T 18883-2022)", the standard limit of formaldehyde has been restricted to 0.08 mg/m3. In order to better promote the implementation and application of this new standard, this study reviewed and interpreted the relevant technical content for determining the standard limit, including the indoor concentration and human exposure levels of formaldehyde, the health effects of formaldehyde, and the derivation of safety reference values. It also proposed prospect for the future development and revision of quality standards for formaldehyde in indoor air.甲醛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）将甲醛限值收紧至0.08 mg/m3。为更好地推动新标准的贯彻和实施，本研究对确定该质量标准的相关技术内容进行了分析和解读，包括甲醛的室内污染水平和人体暴露状况、甲醛的健康效应、安全基准值的推导等，并对未来室内空气中甲醛的质量标准制修订方向提出了展望。.
