Air Toxics data released June 2009
Hamilton County Respiratory Risk Assessment Data
The data presented in this section is from USEPA’s National Air Toxics Assessment (NATA) project and covers the year 2002.
Clicking on the following chemicals will show you google maps of sources of chemicals. for the following set of maps, we selected all the chemicals which have a total “area source” contribution of over one (1) ton for that particular air toxic, in Hamilton County. Both area sources and major sources are mapped. Click on the ballon to learn the amount and whether the source is major or an area source. Some sources have very small emissions, others are large and many small sources can add up to significant emissions. Using google maps, you can see how close you live, work, got to school, etc. to that pollutant.
This spreadsheet shows air toxics by source category (major, area, point source, non-point source, etc). The ‘air toxics by source category’ file is sorted by tons of emissions per year from area sources. Another spreadsheet, for the county, shows amounts of chemicals by facility. (Most facilities have more than one chemical.) A list of air toxics analyzed by USEPA can be found on EPA’s NATA site.
Health impacts can be found at USEPA’s Air Toxics site.

There are other area point sources which emit less than one ton per year. Area point sources (less than 10 tons per year of one hazardous air pollutant and/or less than 25 tons per year of all their hazardous air pollutants combined) which emit over 1 ton per year total 113.69717 tons. Hazardous air pollutants emitted from facilities which individually emit less than one ton of individual hazardous air pollutants, emit a total of 7.822 tons per year in Hamilton County, Ohio.
