This project was to (1) determine concentrations of 28 toxic substances in water, sediments and fishes of 10 rivers in Taiwan; (2) to apply the investigation results for policy-making of toxic substance management; and (3) to update the database of environmental distribution of toxic substances. There were 150 water, sediment and fish samples collected from 10 rivers (each river collected 6 water, 6 sediment and 3 fish samples) in this year. There were 2,610 analytical data obtained, including 360 data from water and 1,560 data from sediments and 690 data from fish samples.

The database searching system for concentrations of regulated toxic substances has been updated with the investigation results in this year.
