Zn-K TXRF–XANES spectrum measured from an airborne particulate matter sample (Hungary) together with reference spectra of Zn compounds. The sample was collected from the city of Paks, Hungary, using the nine-stage May-type cascade impactor (0.3–0.6 µm fraction) onto 20 mm × 20 mm Si wafer forming a stripe with 200–500 µm width and measured at TXRF excitation geometry. |
