Analysis of the chemical data on some odor sources

Since the odor pollution has been controlled, in this ten years the measurement methods of odor substances were developed and the odor grade of each substance was determined. Therefore, today the samples with odor are estimated by chemical analysis. In this paper, the technique of this estimations explained with the exhaust gas from some sewerage plants. The samples were analyzed by GC or GC-MS. And about 30 components, Such as aldehydes, acids, sulfur compounds, nitrogen compounds, etc. were measured. Then, the odor intensity of each compound was calculated by using the equation between the concentration and the odor intensity, which obtained previously, and then, as shown in a table, the main component and its amount is determined with one sample, by which the plan to treat the exhaust is considered respectively. According to such many examinations, it was found that almost all odor sources were able to be analyzed chemically and to be controlled to good advantage
