摘　　要：针对国内外无环境空气质量标准的污染物,环境影响评价工作中常采用阈值估算法、半数致死量估算法、经验公式法估算。为比较三种方法的优劣,本文采用三种方法估算了40种污染物的环境空气浓度限值并与标准值进行比较,结果表明阈值估算法优于半数致死量估算法和经验公式法。For many air pollutants that lack environmental quality standards at present, methods of threshold limit values （TLV） , lethal dose 50% （LD50） and empirical formula were used to estimate them in environmental impact assessment. This paper used the three methods above to calculate concentrations of 40 pollutants in the atmospheric environment, and compared with their environmental quality standards. The results showed that the method of threshold limit values （TLV） was better than the other two methods.
