Engineers and scientists have been warning that plastics waste has increasingly been making its way across larger expanses of land and water throughout much of the world. And it’s no longer accumulating only in the environment but in our bodies. That is the latest warning from environmental engineer and Fulton Schools Professor Rolf Halden and others who have been tracking the growing accumulations of discarded plastics. Halden, director of ASU’s Biodesign Center for Environmental Health Engineering, is among the experts spreading the word that microplastics are in our food, water and air, and that now there is evidence plastic polymers are getting into the human bloodstream. The effects on our health of microplastics in our blood is yet to be understood. So, the news about the increasing presence of plastics inside us is eliciting calls for more research to assess the potential dangers.
