A survey was carried out on an offensive odor at the source as well as on other environmental odors from facilities where fish refuse, animal bone and feather treatment were being carried out among fertilizer plant or fodder plant which act as a source of an offensive odor pollution. The following results were obtained. The method of measurement consists of ASTM type injection syringe method and method of odorometry of Kinoshita type by Odor Research Institute as an organoleptic analysis. A gas chromatography and a Kitagawa type detecting tube methods were carried out as an instrument analysis. The degree of an offensive odor at the drier outlet for treatment of fish refuse was 140-300 by the method of odorometry of Kinoshita type by Odor Research Institute . It was 3-6 X 10<SUP>4</SUP> by the injection syringe method. The degree of odor by the injection syringe method at the outlet of the water-flushing deodorization tower was 4 X 10<SUP>4</SUP>. At the drier outlet for treatment of feathers it was 200-1, 000 by the method of odorometry of Kinoshita type by Odor Research Institute. By the injection syringe method it was 8, 000-100 X 10<SUP>4</SUP>. The odor at the outlet of the water-flushing deodorization tower was mixed, consisting of feather treatment and fish bowel bone treatment odors. It was found to be 250 by the method of odorometry of Kinoshita type by Odor Research Institute, and 12 X 10<SUP>4</SUP> by the injection syringe method. The autoclave exhaust air was 5 X 10<SUP>4</SUP>. At the drier outlet for animal bone treatment it was 200 by the method of odorometry of Kinoshita type by Odor Research Institute, 6 X 10<SUP>4</SUP> by the injection syringe method. Feeding in larger amounts of material than usual resulted in a high odor degree. Heat-treated animal bone and autoclave exhaust emission odors were 6 X 10<SUP>4</SUP>, 40 X 10<SUP>4</SUP>. Analysis of exhaust emissions from each treatment process by gas chromatography revealed the presence of acrolein. It was 36-93 ppm at the drier outlet for fish refuse treatment, 70-352 ppm for feather treatment, and 41 ppm for animal bone treatment. The degree of odor in and around the facilities was 12-50 within a range of 200m and below 10 in the 300-600m range.
