Air Quality Madeling Report Asummary of the health risk assessment is presented below in Table 5-2. As shown, the total combined cancer inhalation risk far total PAH is belew 1 in a million (1 x 105 or 1E-06) and the hazard quotient for each individual PAH with a corresponding RC is below 1. indicating negligible risk.
