The health problems NCEA scientists are working to protect against include respiratory illnesses, cancers, cardiac disease, birth defects, and neurological impairments. To conduct its assessments, NCEA relies on the results of scientific research produced in its sister organizations within EPAs Office of Research and Development and in research centers across the country and around the world. Assessments have been produced for hundreds of compounds including some high-profile ones like asbestos, arsenic, and lead. These are available on-line through a searchable database called the Integrated Risk Information System or IRIS. NCEA scientists also produce high-profile risk assessments known as Air Quality Integrated Science Assessments for six widespread air pollutants that are known to pose health risks.
