| Abstract |
A commercially available turbidimeter, modified by the addition of a magnet, was evaluated for the measurement of asbestos in water. The instrument was used to measure the turbidities of asbestos fiber dispersions in non-boiling still water, as functions of both mass and numerical fiber concentrations, for crocidolite, amosite and chrysotile. Results showed that, for well-characterized water sources, the turbidimeter could be used for routine monitoring of amphibole asbestos fibers at the 1 million fibers per liter (MFL) level, if a simple pre-concentration step was included. Additional modifications would be required before the detection level could be reduced to make the technique useful for monitoring of chrysotile at the 1 MFL level. |
