Benzene, as a major indoor pollutant, has received widespread attention. In order to better control indoor benzene pollution and protect people's health, the limit value of benzene in the"Standards for indoor air quality (GB/T 18883-2022)'' was reduced from 0.11 mg/m3 to 0.03 mg/m3. This study reviewed and discussed the relevant technical contents of the determination of benzene limit value, including the exposure status of benzene, health effects, and derivation of the limit value. It also proposed prospects for the future direction of formulating indoor air benzene standards.
苯作为主要的室内污染物受到广泛关注。为了更好地控制室内苯污染，保护人群健康，我国新颁布的《室内空气质量标准》（GB/T 18883-2022）将苯的浓度限值从0.11 mg/m³收紧为0.03 mg/m³。本研究对确定该卫生限值的相关技术内容进行梳理和讨论，包括苯的暴露情况、苯对人体健康的影响和苯标准限值的推导等，并提出了未来室内空气中苯标准修订方向的展望。.
