Notes | When juvenile salmonids migrate downstream towards the ocean, they can encounter and absorb harmful chemicals such as DDT, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and pesticides. The authors of this paper measured harmful chemicals in tissues of juvenile salmonids, and in their prey. They also measured stomach contents of salmon from estuaries and hatcheries. Results were not surprising: industrial estuaries such as the Columbia River, Coos Bay and Yaquina Bay showed high contaminant exporsure (Yaquina Bay was high in PCBs in Chinook salmon), while natural estuaries like the Salmon and Elk River estuaries, had low exposures to harmful chemicals. Some of the conservation estuaries, including Alsea Bay, had relatively high exposures to contaminants. . Juvenile Chinook were more vulnerable than coho salmon. |
