| 摘 要： | 为研究环境空气恶臭污染特征，以天津市区为研究区域，分别在夏秋两季对天津市内六区的环境空气中恶臭感官浓度进行了监测。结果显示，在观测期间臭气浓度在限值（以《恶臭污染物排放标准》厂界臭气浓度限值20作为参照）范围以内的样品数量夏季占63％，而秋季占18％；通过多元线性回归方法建立了典型恶臭污染物与恶臭感官浓度的定量表达式，计算出典型恶臭污染物对市区环境空气的臭气浓度贡献率占59％。通过对实测值与预测值的拟合情况的分析，表明该回归方程可以较好的预测天津市环境空气中夏季恶臭感官浓度。

| Abstract: | In order to investigate the pollution characteristics of ambient air odor, this study tested the odor sensory concentra- tions in ambient air across six districts of Tianjin in summer and autumn, respectively. The results show that the percentage of samples within the odor concentration limits （20%） was 63% and 18% in summer and autumn. A quantitative expression of the typical odor pollutants odor sensory concentration was established by the method of multiple linear regressions. Calculation results show that 59% urban ambient air odor pollution was derived from the typical odor pollutants. Analysis on fitting situation between the measured and predicted values indicates that the regression equation can better predict the ambient air odor sensory concentra- tion in summer. |
