HEI Special Report 16, "Mobile-Source Air Toxics: A Critical Review of the Literature on Exposure and Health Effects" summarizes the health effects of exposure to the 21 Mobile-Source Air Toxics (MSATs) defined by the U.S. Environmental Protection Agency’s 2001 rulemaking and critically analyzes the literature for a subset of seven important MSATs (acetaldehyde, acrolein, benzene, 1,3-butadiene, formaldehyde, naphthalene, and polycyclic organic matter). An Expert Special Panel reviewed the literature on MSATs and assessed and summarized research gaps and unresolved questions, as understood in the context of the current regulatory agenda.

The Report focuses on MSATs for which mobile sources are a sizable source of human exposure and for which existing data suggest that health effects might be observed at concentrations approaching those found in
ambient air. For each MSAT, the following questions are addressed:

(1) To what extent are mobile sources a significant source of exposure to this MSAT?
(2) Does this MSAT affect human health?
(3) Does this MSAT affect human health at environmental concentrations?

The report also includes an extensive hyperlinked database of the most current sources of information on each of these substances.
