Overview
The team quantify chemical substances in fishes and molluscs to monitor the their pollution induced by tsunami. We also estimate the trophic positions of these samples to better understand the pollution reality with considering the bioaccumulation of chemical substances.

Overview of the Observation

Results and Future Plan
We collected organisms and sediments and determined abundance of PCBs.
