TEMPE, Ariz. -- Arizona State University researchers will lead a multi-university project to aid industry in understanding and predicting the potential health and environmental risks from nanomaterials.
Nanoparticles, which are approximately 1 to 100 nanometers in size, are used in an increasing number of consumer products to provide texture, resiliency and in some cases antibacterial protection.
The U.S. Environmental Protection Agency (EPA) has awarded a grant of $5 million over the next four years to support the LCnano Network as part of the Life Cycle of Nanomaterials project, which will focus on helping to ensure the safety of nanomaterials throughout their life cycles from the manufacture to the use and disposal of the products that contain these engineered materials.
Paul Westerhoff is the LCnano Network director. Westerhoff is the associate dean of research for ASU's Ira A. Fulton Schools of Engineering and a professor in the School of Sustainable Engineering and the Built Environment.
The project will team engineers, chemists, toxicologists and social scientists from ASU, Johns Hopkins, Duke, Carnegie Mellon, Purdue, Yale, Oregon's state universities, the Colorado School of Mines and the University of Illinois-Chicago.
Engineered nanomaterials of silver, titanium, silica and carbon are among the most commonly used. They are dispersed in common liquids and food products, embedded in the polymers from which many products are made, and attached to textiles, including clothing.
Nanomaterials provide clear benefits for many products, Westerhoff says, but there remains "a big knowledge gap" about how, or if, nanomaterials are released from consumer products into the environment as they move through their life cycles, eventually ending up in soils and water systems.
"We hope to help industry make sure that the kinds of products that engineered nanomaterials enable them to create are safe for the
