摘　　要：为了解天津市工业区氨气污染现状,于夏、秋季节对该地区氨气进行监测采样.分析结果表明,夏季氨气的平均浓度要明显高于秋季.氨浓度要低于我国厂界一级标准限值,不过与欧洲环境质量标准比较,大部分都高于标准中目标限值的要求.氨的气味品质是厌恶型,厌恶度和浓度指数二者之间的关系,符合二次多项式模型;当厌恶度为-1时,氨的臭气浓度值为45,此浓度下人们开始感到身心不愉悦.基于此,建议将臭气浓度值45,作为氨环境影响限值的参考值,即使只是理论层面的研究,也可以为氨控制标准的制定指引一个新的方向.To understand the contamination status of the malodorous gas in Tianjin industrial estate, the sample of NH3 in that area had been monitored and it showed that, the average concentration of NH3 in Summer was apparently higher than that in Autumn. Although the NH3 concentration is in the limitation of the standard of the plant community, it is higher than that in European countries. The hedonic tone of NH3 is belongs to unpleasant, the unpleasant increases with the increase in their odour concentration index. The fitting results showed a quadratic polynomial relationship between the hedonic tone and odour concentration for NH3. From the characteristic curve of hedonic tone, we can define H of-1 as acceptable, and the odour concentration(45) at this point could be proposed as impact criteria.
