Air Quality – Fine Particulate Matter (PM2.5) by Census Tract, 2012
This layer displays the percentage of days with concetrations of ozone matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter.
This layer displays the percentage of days with concetrations of ozone matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter.
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood of hazardous exposure per 1 million population.
This layer displays the daily average concentration of ozone and the percentage of days with concetrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2014.
This layer displays the daily average concentration of fine particulate matter and the percentage of days with concetrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2014.
Layer displays the modelled 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.
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood of hazardous exposure per 1 million population.
This layer displays the locations of regulated facilities that discharge air pollutants in the United States. The Air Facility System (AFS) contains compliance and permit data for stationary sources of air pollution (such as electric power plants, steel mills, factories, … Continued
This layer displays the locations of air quality monitoring stations in the United States. The Air Quality System (AQS) contains ambient air pollution data collected by EPA, state, Local, and tribal air pollution control agencies from thousands of monitoring stations. … Continued
This layer displays the amount of toxic releases based on the Environmental Protection Agency (EPA) Toxics Release Inventory (TRI), a national program which tracks the management of over 650 toxic chemicals that pose a threat to human health and the … Continued
