Columbia Riverkeeper tests find toxics in fish bound for dinner tables

Before they landed on local fishermen’s plates this summer, an environmental group tested five Columbia River fish to see what toxics lay within.

The results of Columbia Riverkeeper’s analysis weren’t unexpected, and for resident fish, they weren’t good.

The worst? Two walleye, which had high levels of PCBs, polychlorinated biphenyls, cancer-causing industrial chemicals banned in 1979 that accumulate up the food chain in fish.

One had 175 times more PCBs than EPA consumption guidelines allow.
