This indicator reports the respiratory Hazard Index (HI) from the analyzed carcinogens in ambient outdoor air. The HI is the sum of hazard indices for those air toxics with reference concentrations based on respiratory endpoints, where each hazard index is the ratio of exposure concentration in the air to the health-based reference concentration set by…
This indicator reports the estimated concentration of diesel PM in air. The value of the indicator is in µg /m3. Areas with higher diesel PM levels (i.e., more harmful to human health) are placed higher in percentile (national ranking). The percentile could be interpreted as, for example, for a place at the 80th percentile nationwide,…
This indicator reports the estimated lifetime inhalation cancer risk from the analyzed carcinogens in ambient outdoor air. The value of the indicator is persons per million lifetime. Areas with higher air toxics cancer risk levels (i.e., more harmful to human health) are placed higher in percentile (national ranking). The percentile could be interpreted as, for…
