Layer displays the modeled cancer risk associated with air toxics exposure. Figures represents the likelihood of hazardous exposure per 1 million population.
Real-time Air Quality Index (AQI) – Ozone and Particulate Matter
This US EPA feature layer is updated hourly and reflects the latest hour of air quality data received from each monitoring site that reports to AirNow. The concentration and AQI values are for Ozone and Particulate Matter (PM) only. Air … Continued
Air Toxics – Non-Cancer Risk by Census Tract
Layer displays the modeled non-cancer risk associated with air toxics exposure. A hazard index (HI) of 1 or lower means air toxics are unlikely to cause adverse noncancer health effects over a lifetime of exposure.
