摘要：

Seawater from Japanese coastal areas was extracted with a XAD-2 resin column for a study of PCDDs and PCDFs. 1.3 - 2.9 pg/L of PCDDs were detected, but no PCDFs were found. The most of detected PCDDs was OctaCDD and some HeptaCDDs. This isomer pattern is similar to non-polluted atmosphere and sediment. We could not define the source of PCDDs in seawater. However it is of interest that the composition of PCDDs in seawater is similar to natural dioxin found in ancient oceanic sediment.
