摘　　要：近年来,化工园区突发大气环境污染事故频发,为有效评价突发大气污染事故的影响程度,急需建立恰当的有毒有害气体危害阈值体系。本研究通过对比分析IDLH、LC50、AEGLs、ERPGs、TEELs、PACs等国内外有毒有害气体危害阈值数据的由来、意义及适用条件,建议在进行有毒有害气体泄漏危害事件预测和后果分析中,有毒有害气体危害阈值建议采用的优先顺序为:AEGLs>PACs>ERPGs>TEELs>IDLH>LC50。In recent years, the sudden air environmental pollution accidents of chemical industry parks occurred frequently. In order to assess the environmental influence of them, it was necessary to establish a appropriate damage threshold system of toxic and harmful gases. Compared with the origin, significance and applicable conditions, such as IDLH, LC50, AEGLs, ERPGs, TEEL s and PACs, it was suggested that the damage threshold can be prioritized as follows ： AEGLs 〉 PACs 〉 ERPGs 〉 TEELs 〉 IDLH 〉 LC50.
