Contaminants linked to sturgeon decline in Columbia river
... contamination," Schreck said. "The fish move, the stuff they eat moves and the water and sediments bearing the contaminants moves. The Columbia receives input from numerous sources, so any population of fish at any one site can be exposed to a myriad of substances."

There is scant evidence of impacts at the time of other major extinctions e.g.,...Chemists report progress in quest to use hydrogen as fuel for cars and electronic devices
