Description: This service contains annual concentrations measured at monitoring sites for air toxics covered in the 2019 AirToxScreen. These sites were not used directly to generate the AirToxScreen risk estimates because nationwide there are too few sites and monitored air toxics. For sites and pollutants with sufficient monitored values, measurements are summarized to indicate the distribution of measured concentrations. We provide concentrations for the AirToxScreen year, 2019, plus other years with enough monitoring data for us to compute annual concentration averages.
