Therefore increasing attention has been paid to various mobile and area sources and other efforts to control residual risks.
Ambient air pollution, especially in urban environments, arises from a spectrum of different sources, which are broadly classified as stationary, mobile, and area emission sources.
The models were also run for the source categories separately and showed strong gradients for mobile and area emission sources and nonsignificant effects for point sources (data not shown).
Separate modeling by source category showed similar results for mobile and area emission sources, but not for point sources, where persistent segregation gradients for the total population and for each racial group were not observed.
Although the relative contribution of a particular source or source category may vary from place to place, it is the blending together of combined emissions from numerous point, mobile, and area sources that makes Houston's air quality unhealthful.
The EPA National Air Toxics Assessment (NATA; U.S. EPA 2009b), which is currently available to the public with 2002 data, estimates ambient concentrations at the census-tract level (large scale) for mobile and area source emissions and at the census-block level (small scale) for major stationary source emissions].

The U.S. EPA estimates HAPs concentrations using a Gaussian air dispersion model that combines emissions inventories from mobile, point, and area sources with data on local meteorology, chemical decay rates, secondary formation, and deposition (Rosenbaum et al. 1999; Woodruff et al. 1998).
