我国VOCs的排放特征及控制对策研究

挥发性有机物(volatile organic compounds,VOCs)是一类具有刺激性、致畸、致癌、致突变作用、易燃易爆的有机物,对人体和生态系统健康有很大危害.本文从工业固定源、机动车尾气排放源和日常生活源等角度分析不同排放源的VOCs排放特征,绘制并分析了我国重点区域重点行业VOCs排放的空间分布格局,甄别出东部沿海地区VOCs 2010年总量和单位面积均高于中西部地区,且工业产生源有明显差异.进一步归类分析了欧美等发达国家针对VOCs排放控制的政策法规,对比分析我国目前治理VOCs的有关法规和标准,提出了现阶段我国VOCs管理存在的问题,并提出了相应的控制对策建议.

Characteristics and Countermeasures of Volatile Organic Compounds (VOCs) Emission in China

Volatile organic compounds (VOCs) are a kind of irritating, carcinogenic, deforming, mutagenic, flammable and explosive organic compounds which are harmful to human and ecosystem health. In terms of industrial stationary sources, vehicle exhaust sources and domestic emission sources, this paper analyzed the major characteristics of VOCs emissions. The spatial distribution of industrial VOCs emission in China's typical areas were figured out based on the statistic data issued in 2010. The results showed that the emission quantity in eastern areas was higher than that in middle and western areas, not only by total amount but also by unit area, while there was a significant difference among these areas in terms of industrial emission sources. Therefore, the current VOCs governance, including regulations, standards, and existing problems were discussed, and then based on the experiences from the developed countries and regions, the suggestions were proposed to enhance the VOCs management in China.
