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 2017.
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 2017.
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 are assigned by repeating each parent tract level value.
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood 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.
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.
