Abstract

The U.S. Environmental Protection Agency (EPA) promulgates national ambient air quality standards (NAAQS) on the basis of scientific information contained in integrated science assessments (ISAs), formerly known as air quality criteria documents (AQCDs). The ISA is a concise review, synthesis, and evaluation of the most policy-relevant science, and it communicates critical science judgments relevant to the NAAQS review. A more recent ISA for carbon monoxide (CO) was completed in 2010, and is available under downloads.

In 1991, EPA released a revised criteria document for CO which reviewed the latest evidence available at the time regarding sources, atmospheric chemistry, population exposure, dosimetry, pharmacokinetics, and health effects of CO, including effects in susceptible populations. This document was revised and updated in 2000. The 2000 CO AQCD is available under downloads.
