Scientists and engineers, along with health and environmental organizations, are become increasingly concerned about the amount of plastics around the world. That’s not only because plastics waste is adding significantly to the growing amount of refuse in landfills and is polluting oceans. It’s also because of the growing potential for negative impacts on the health of humans and wildlife. Fulton Schools Professor Rolf Halden, director of ASU’s Center for Center for Environmental Health Engineering, say it’s now almost impossible to find humans and animals who haven’t been exposed to plastics and possibly also to toxic additives used in manufacturing them.
