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 2018.
Air Quality – Fine Particulate Matter (PM2.5) by Census Tract, 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.
Air Toxics – Non-Cancer Risk by Census Tract
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.
Air Toxics – Cancer Risk by Census Tract
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood of hazardous exposure per 1 million population.
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.
Air Toxics – Cancer Risk by Census Tract
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood of hazardous exposure per 1 million population.
Air Quality – Fine Particulate Matter (PM2.5) by Census Tract, 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.
Air Quality – Ozone Levels (O3) by Census Tract, 2014
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.
