Determining a risk level posed by an air pollutant

摘要

A method and system for determining an amount of risk an air pollutant poses to a subject. A risk level is calculated by determining a dosage of the air pollutant, received by the subject over a predetermined period of time, and obtaining historic information about historic dosages of the air pollutant. The risk level is then calculated using the dosage and the historic information to thereby determine a risk level associated with the accumulated deposition of the air pollutant in the portion of the subject's respiratory tract.
