abstract
In the Ashida river and Hironishiohkawa of Hiroshima Prefecture, PCB water contents, sediments, and aquatic organisms were detected.
The results can be summarized as follows:
1) Not all the water samples contained PCB.
2) PCB contents in fish and shellfish in the Ashida river reached 0.01 and 0.24 mg/kg.
3) The PCB distribution pattern in different grain-sized sediments in both rivers points out that PCB was distributed mostly in smaller grain-size sediments.
Therefore, analysis of PCB in sediments should take special account of the grain size.
