The air toxics respiratory HI indicator is the respiratory HI from the analyzed carcinogens in ambient outdoor air, as provided by the 2017 Air Toxics Data Update. The data is reported at the Census tract level. Block group level values … Continued
The traffic proximity indicator is based on AADT count divided by distance in meters from the Census block centroid. The proximity score is based on the traffic within a search radius of 500 meters (or further if none is found … Continued
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the likelihood of hazardous exposure per 1 million population.
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 locations of brownfield sites based on the September 2013 version of the EPA Assessment, Cleanup and Redevelopment Exchange System (ACRES) database.
This layer displays RSEI score by county. A RSEI Score is a unitless value that accounts for the size of the chemical release, the fate and transport of the chemical through the environment, the size and location of the exposed … Continued
This layer displays the percentage of days with concentrations 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 likelihood of hazardous exposure per 1 million population.
This layer displays the daily average concentration of fine particulate matter and the percentage of days with concentrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2014.
This layer displays the daily average concentration of ozone and the percentage of days with concentrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2014.
