Science: Source Apportionment.

Source Apportionment

Source Apportionment studies refer to studies which attempt determine the sources of various air pollutants at a particular location. These studies are just beginning to be performed. As Burning Issues acquires the results of additional studies, we will happily post them on our site.

This study compares two sites in downtown San Jose, CA. Refer to Table 3 showing the the relative proportions of pollution sources in San Jose. Note that the pollution from wood smoke is 4.4 times that of gasoline vehicles and 8.2 times that of diesel emissions.
