Abstract Procedures used by a number of laboratories for the analysis of asbestos fibers in water samples were investigated using standardized aqueous dispersions of chrysotile, crocidolite, and taconite tailings. Filtration problems when using polycarbonate filters were solved, and an optimum filtration technique was developed that permits microscopically uniform deposits to be obtained. Replicate analyses established fiber losses and reproducibility of five filter preparation techniques. The uniformity of the deposits on all the final electron microscope preparations was expressed quantitatively, and the most satisfactory performance was given by all of the Nuclepore techniques. Ultrasonic treatment at 20 kHz increased fiber concentrations of chrysotile suspensions but had no effect on crocidolite suspensions.
