Analytical method for Octachlorodibenzo-p-dioxin (OCDD) in sea foods was studied by ECD-gas chromatography and mass fragmentography. The sample was extracted with hexane in an Omni-Mixer. The concentrated extract was chromatographed over a Florisil column and the column was eluted with 30 ml of hexane and 150 ml of ethyl acetate. The second eluate was purified by chromatography over alumina column, the column was eluted with 100 ml of 5% ether in hexane, and the eluate was used for analysis of OCDD by ECD-gas chromatography and mass fragmentography. Detection limit and minimum amount of OCDD that could be detected by ECD-gas chromatography were 0.01 ng and 0.2 ppb, respectively. Recovery of OCDD added to homogenized samples (fortification level, 0.1 ppm) was 85.3% in average. Detection limit and minimum amount of OCDD that could be detected by mass fragmentography were 0.01 ng and 0.1 ppb, respectively.
