Stormwater runoff containing a poisonous compound from car tires that washes into streams is deadly to protected coho salmon, Pacific steelhead, and Chinook salmon, based on new research revealed right this moment.

In distinction, sockeye salmon appear largely unaffected by the identical compounds.

The newly recognized danger to steelhead and Chinook salmon may assist inform mitigation efforts for the development and overhaul of highways on the West Coast to make sure that future runoff is much less deadly to salmon and steelhead. Some western states have already begun designing highways with inexpensive filtration measures proven to guard salmon.
