Health Assessment and Translation

About OHAT

The Office of Health Assessment and Translation (OHAT)  (formerly Center for the Evaluation of Risks to Human Reproduction (CERHR)) serves as an environmental health resource to the public and to health research and regulatory agencies.

• Conducts technical assessments focused on understanding the potential for adverse effects on human health by agents, substances, mixtures, or exposure circumstances (collectively referred to as “substances”). These evaluations can lead to NTP  opinions on whether these substances may be of concern given what is known about current human exposure levels.
• Organizes workshops or state-of-the-science evaluations to address other issues of importance in environmental health sciences.
