  • Chemicals with risk ratios greater than or equal to 1 are in bold.
    Risk Ratios based on noncarcinogenic effects are in italics.
    The symbol ug/m3 is micrograms per cubic meter, the amount (in micrograms) of a chemical in a cubic meter of air. This is also known as a concentration.
    For diesel particulate matter, onroad and nonroad concentrations include a model-estimated background concentration.
    *Acetaldehyde, acrolein and formaldehyde concentration estimates include secondary formation, which is the process by which chemicals in the air are transformed into other chemicals.
    **PAH/POM is "polycyclic aromatic hydrocarbons/polycyclic organic matter." These define a broad class of compounds. The chemicals making up this class were broken up into 8 groups based on toxicity, and each group was assigned a cancer-weighted toxicity estimate. 0.0072 ug/m3 is the health benchmark average across the 8 groups.
