• A highly sensitive detection method of PCDDs in environmental water was developed by the concentration method using polyamide columns. PCDDs in water samples were adsorbed first to a polyamide column to which 2-chlorodibenzo-p-dioxin (MCDD) and octachlorodibenzo-p-dioxin (OCDD) were shown to be adsorbed quantitatively. The PCDDs, then, were eluted from the column by ethanol and dichloromethane containing 1% acetic acid. The eluted MCDD and OCDD were analyzed and quantified by GC-MS-SIM with 97% and 98% of recovery, respectively. By this method, the levels of PCDDs were determined in environmental water taken at four points of Tokyo Bay and four points of river flue into Tokyo Bay. The highest PCDDs levels were obtained from the sample of Arakawa River with a level of about 400 pg/liter. The concentration method using polyamide column could be used in routine work since this method enables to quantify efficiently PCDDs even at ppq levels.
