Studies of the elemental content of reaerosolized coal fly ash revealed increased concentrations of biologically active trace elements, Cd, Co, Cr, Cu, V, and Zn, compared to the initial stock material. Concentrations of the matrix elements, Al, Si, and Ti, were not altered during reaerosolization. Because of the absence of concentration dependence on particle size and on analytical recovery experiments, aluminum was chosen as an indicator element for quantification of lung-deposited fly ash in rat inhalation studies. Calculated lung depositions for inhaled fly ash were in agreement with expected values.
