The article "Impact of Free Calcium Oxide Content of Fly Ash on Dust and Sulfur Dioxide Emissions in a LigniteFired Power Plant" (D. Sotiropoulos, A. Georgakopoulos, and . Kolovos, Journal of Air and Waste Management, 2005:1042-1049) presents measurements of dust emissions, in \(\mathrm {mg/m}^3\), for four power plants. Thirty measurements were taken for each plant. The sample means and standard deviations are presented in the following table:

Mean
