大气挥发性有机化合物环境基准研究进展与展望

挥发性有机化合物(VOCs)中的许多物种对人体具有危害性,同时,VOCs对大气环境产生着重要的影响。目前我国部分区域大气VOCs污染已经十分严重,控制大气VOCs污染对于改善环境空气质量,保护人体健康具有重要意义。国际上许多国家或国际组织制定了大气VOCs环境基准或者发布了大气VOCs环境基准指导值,这对于加强VOCs污染控制及环境管理可以起到重要作用。我国尚未制定大气VOCs环境基准,亟待开展系统的研究工作。在综述国际大气VOCs环境基准研究进展,介绍当前我国大气VOCs环境基准研究情况的基础上,分析了我国大气VOCs环境基准的研究需求,并对今后的系统研究提出了建议。

Advances and Prospective of Research on Atmospheric Environment Criteria of VOCs

Many species of volatile organic compounds (VOCs) may have a variety of harmful health effects to human beings, and VOCs play a significant role in the atmospheric environment. The pollution of VOCs in the atmospheric environment of some regions in China has become a serious problem in recent years; therefore, pollution control of VOCs in the atmospheric environment is important for the improvement of ambient air quality and the protection of human health. Atmospheric environment criteria of VOCs have been formulated in some developed countries or ambient air quality guidelines of VOCs have been designated by some international organizations, which is very helpful to the implementation of the control countermeasures of VOCs in the atmosphere or to the environmental management of VOCs pollution. However, atmospheric environment criteria of VOCs have not been developed in China up to now, thus it is necessary to carry out the systematic research work in this field in China. In this paper, some atmospheric environment criteria of VOCs formulated by developed countries and international organizations were first summarized, then the study status of atmospheric environment criteria of VOCs in China was introduced, and the research needs of atmospheric environment criteria of VOCs in China were analyzed. Finally, the suggestion was put forwarded for the future research on atmospheric environment criteria of VOCs in China.
