For the last eight years we've been conducting research at Simon Fraser University in Vancouver. We've been looking at the fate of phthalate esters in the environment. We know they biodilute. They do not bioaccumulate. They don't stay in the environment.
We've been looking at about 26 different species. As you go up the species range, you get fewer and fewer phthalates, so they do biodilute. We know they're not around forever.
