The Science of Public Health Protection

Toxicology Excellence for Risk Assessment joined the Department of Environmental Health, at the University of Cincinnati’s, College of Medicine on August 1, 2015.  We are now the Toxicology Excellence for Risk Assessment Center at the University of Cincinnati (the TERA Center at UC).  Read more here.


At TERA, we conduct our work at the intersection of science and health protection. Chemicals are an important part of our daily lives. Some chemicals are essential to a healthy life, but exposure to chemicals may also present health risks. TERA studies the way our bodies interact with the chemicals around us to determine the nature and extent of health risks.


Founded as an independent non-profit organization, TERA is dedicated to scientific collaboration and transparency in support of public health protection. We strive for broad communication of risk science by providing risk managers, legislators, and ordinary citizens with the toxicology information they need to make important decisions about chemical safety.

The Independent Charities Seal of Excellence is awarded to the members of Independent Charities of America and Local Independent Charities of America that have, upon rigorous independent review, been able to certify, document, and demonstrate on an annual basis that they meet the highest standards of public accountability, program effectiveness, and cost effectiveness.  These standards include those required by the US Government for inclusion in the Combined Federal Campaign, probably the most exclusive fund drive in the world.  Of the 1,000,000 charities operating in the United States today, it is estimated that fewer than 50,000, or 5 percent, meet or exceed these standards, and, of those, fewer than 2,000 have been awarded this Seal.
