摘　　要：系统介绍了我国建筑室内VOC的定义、来源、浓度、健康危害、评价标准、控制技术的研究应用现状,总结了过去10多年我国在室内VOC控制方面采用的技术途径及效果.基于未来室内环境VOC控制指标数量、限值、健康风险等的发展趋势,同时结合室外源、室内固定源和活动源的特征,提出了我国近期和未来应当采取的技术路径,以及工程、产品、环境质量评估方面面临的主要任务.In China,VOC pollution in indoor air is quite serious,and the control of VOC concentration in indoor air has always been a difficult problem.It is also an important control target of healthy buildings in China,since VOC has significant health hazards to human body.This paper introduces the definition and source of volatile organic compounds in indoor air,analyses the present situation of pollution and expounds the human hazards of VOC.There are differences between VOC control indexes in China and other countries in terms of indoor air quality standards.In the future revision of standards,health needs,industry status and implement ability should be fully considered.There are three ways to control indoor VOC pollution:Source control,ventilation dilution and air purification.Source control is the most fundamental way to avoid indoor air pollution.The identification of"health performance"of building materials and furniture products will be the main development direction.The main idea of control is"release rate"instead of"content"control method.For high-risk substances,developing alternative products is the most direct solution,but this method depends on technological progress.Diluting indoor air pollutants with outdoor fresh air is the most convenient way to reduce VOC concentration.How to achieve precise ventilation according to the emission characteristics of pollution sources will be the main task of ventilation research in healthy buildings.Air purification is an indispensable means of controlling indoor air pollution in modern buildings.With the standard limit of VOC concentration in indoor environment getting lower and lower,the application of air purification technology will be more and more widely.High CADR,high CCM,low resistance and no secondary pollution will become the main development direction.Since 2017,JGJ/T 436-2018(Technical Standard for Interior Decoration Pollution Control of Residential Buildings)and JGJ/T 461-2019(Design Standard for Controlling Indoor Air Quality of Public Building)have been re
