Analysis of fibres in human lung tissue.

Abstract
Standard UICC [International Union Against Cancer] crocidolite fibers and fibers extracted from occupationally exposed human lung tissue were analyzed by scanning electron microscopy after different preparation procedures. A significant fiber loss was due to the adhesion of fibers to the breakers. Fibers were also discarded during the washing and extraction of the lung tissue samples. The recovery was 30-40% for UICC standard specimens and lung tissue samples.
