  • Chemicals with risk ratios greater than or equal to 1 are in bold.
    Risk Ratios in italics are based on noncarcinogenic effects.
    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.
