Research continues to raise alarm about the impacts of the microplastics to which many people have become widely exposed. The tiny plastic particles that are in the air, water, food and many common materials and objects are more prevalent than ever. The nearly continuous exposure to microplastics is a growing and potentially serious risk to human health, say experts such as Rolf Halden, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. Halden, director of ASU’s Biodesign Institute Center for Environmental Health Engineering, stresses the need for public education to inform people how to reduce their exposure to the threatening microparticles.
