Reference Methods for Measuring Airborne Man-Made Mineral Fibres (MMMF)

摘要

The WHO/EURO Technical Committee on Monitoring and Evaluating Airborne MMMF, consisting of experts from six countries, has developed an international reference scheme to harmonize evaluation, fibre counting and sizing procedures and to assess counting differences between laboratories participating in the scheme. The volume summarizes the progress made on the scheme in harmonizing fibre counting levels by the use of standard evaluation procedures and regular interlaboratory sample exchanges. Also included are the reference methods for monitoring concentration of fibres using a phase contrast optical microscope and for determining size of fibres using a scanning electron micoscope.
