Abstract |
A methodology has been developed for the determination of amount and size distribution of asbestos fibers and fibrils in air at point sources and near point sources. The technique can also be applied to ambient air samples. The method employs a scanning electron microscope with microprobe capability and an image analyzing system. Complete details for manual operation have been worked out. Feasibility study for automated operation has been completed also. Preliminary results of analysis of samples collected at point sources and near point sources are also included. (Author) |
