摘　　要：三氯乙烯和四氯乙烯具有明确室内空气污染来源,大量流行病学证据证实其具有致癌毒性和非致癌毒性,已有多个国家和国际相关组织关注室内空气三氯乙烯和四氯乙烯。基于三氯乙烯和四氯乙烯健康风险评估最新研究结果,我国新颁布的《室内空气质量标准》(GB/T 18883-2022)新增指标三氯乙烯和四氯乙烯,指标要求分别为8 h浓度均值6、120μg/m^(3)。本文对室内空气中三氯乙烯和四氯乙烯标准限值制定相关的技术内容进行了分析和讨论,包括室内空气三氯乙烯和四氯乙烯的来源、暴露状况、健康影响和标准限值的确定等,并对标准实施提出建议。There are clear indoor air pollution sources of trichloroethylene and tetrachloroethylene.A large number of epidemiological evidence has confirmed their carcinogenic toxicity and non-carcinogenic toxicity.Several countries and international organizations have paid attention to indoor air trichloroethylene and tetrachloroethylene.It has been also assessed that there should be certain potential health risk of indoor air trichloroethylene and tetrachloroethylene in China.Based on the latest research results of health risk assessment of indoor air trichloroethylene and tetrachloroethylene,the"Standards for indoor air quality(GB/T 18883-2022)"added trichloroethylene and tetrachloroethylene as indicators.The index limit of trichloroethylene is 6μg/m3 for an 8-hour average concentration.The index limit of tetrachloroethylene is 120μg/m3 for an 8-hour average concentration.The technical contents related to the determination of the standard limits of trichloroethylene and tetrachloroethylene in indoor air were analyzed and discussed,including the sources,the exposure,the health effects,the determination of the limit values,and the recommendations for standard implementation.It also proposed recommendations for the implementation of"Standards for indoor air quality(GB/T 18883-2022)".
