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/m. 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.
甲醛作为室内空气中的一种重要污染物，一直备受关注。在新发布的《室内空气质量标准（GB/T 18883-2022）》中，甲醛的标准限值已被限制为0.08毫克/立方米。为了更好地推动这项新标准的实施与应用，本研究对确定该标准限值的相关技术内容进行了回顾与解读，包括甲醛的室内浓度和人体暴露水平、甲醛对健康的影响以及安全参考值的推导。同时，还对未来室内空气中甲醛质量标准的发展与修订提出了展望。
