摘要
道路石油沥青在加工和使用过程中,会持续释放出大量具有毒性和致癌性的挥发性有机化合物(volatile organic compounds, VOCs),这些气体会对环境和人类造成严重危害。归纳了境内外研究成果,总结了道路石油沥青VOCs的主要成分;从环境及人类健康角度探讨了道路石油沥青VOCs的危害;综述了不同环境特征下道路石油沥青有害气体的释放机理;最后,将道路石油沥青生命周期分为4个阶段,对道路石油沥青全寿命周期VOCs的排放特征进行了分析;在此基础上,提出完善评价道路石油沥青VOCs危害的统一标准、从微观角度探究其释放机理、研发在开放环境中准确测量VOCs组成和浓度的测量方法是目前亟待解决的问题。
During processing and utilization of road petroleum asphalt,a large amount of toxic and carcinogenic volatile organic compounds(VOCs)are continuously released,which can cause serious harm to the environment and humans.In the paper,the domestic and international research results are concluded,the main components of road petroleum asphalt VOCs are summarized;the hazards of road petroleum asphalt VOCs are discussed from the perspective of environment and human health;reviews the release mechanism of road petroleum asphalt harmful gases under different environmental characteristics;finally,the life cycle of road petroleum asphalt is divided into four stages,and the emission characteristics of VOCs of road petroleum asphalt throughout its life cycle are analyzed;on this basis,it is put forward that improve the unified criteria for evaluating the hazards of road petroleum asphalt VOCs,explore their release mechanisms from a microscopic perspective,and develop measurement methods for accurately measuring the composition and concentration of VOCs in an open environment are issues that need to be addressed.
