For the fish Surfactant poisoning, I wonder. Gulf oil spill.
Birds, surfactant contmination: Pockets of released surfactants swept up in thunderstorms and falls with rain on birds. Feathers no workie, bird slams to ground.
In an Arkansas River???
That's an algore-basm ... Surfactants aren't poisonous ... you're playing right into their hands with a statement like that.
