| Abstract | The potential of microscopic characterization of fibrous and environmental particles was discussed with two examples from recent laboratory experience. Examples of the characterization of surface modified asbestos (1332214) particles using conventional secondary ion mass spectroscopy, electron spectroscopic imaging, and electron energy loss spectroscopy were given. The secondary ion images of titanium and titanium-oxide may be used to selectively indicate the contour of the asbestos fiber. The titanium ion images demonstrated that, within the lateral resolution of the ion microprobe, the titanium reacted fairly evenly over the selected area of the chrysotile (12001295) surface and no evidence of any significant build up of localized titanium containing compounds was found. The application of the scanning proton microprobe (SPM) method to characterize the North Sea aerosol was discussed. An attempt was made to quantitatively estimate from field measurements the atmospheric input of heavy metals into the North Sea and to evaluate the nature of the aerosol particles responsible for this flux. By using the scanning proton beam it was possible to reveal elemental distributions within a single aerosol particle structure. Detected total amounts for sulfur (7704349), chlorine (7782505), potassium (7440097), calcium (7440702), titanium (7440326), vanadium (7440622), chromium (7440473), iron (7439896), nickel (7440020), and zinc (7440666) were in the range of 0.01 picograms for zinc to 390 picograms for chlorine. |
