PORTLAND, Ore. (KOIN 6) — A new study found some fish in the Columbia River contain toxic chemicals.

According to the study conducted by scientists at the U.S. Geological Survey, the chemicals found could cause health concerns for people who eat large quantities of the fish known as largescale suckers.

The study found several of the chemicals are at levels that exceed the safe standards and could have an adverse effect on the river system’s food web in general.

Contaminants included pesticides, flame retardant compounds and ingredients from common household products.
