... Most of these studies were undertaken to improve the source identification and support decision making. These studies were informational rather than regulatory; there was a desire by decision makers to understand the relative contributions from different source types.
From page 354...
... The major sources including coal combustion dust, fugitive dust (soil dust) , and construction dust accounted for 58 percent at Xi'an (Zhang X.Y.
