Abstract

Lead in urine has been determined for many years. Several excellent methods are described in the literature. With the exception of the method of Vander-kolk and Van Farowe, these methods generally require wet ashing of the urine prior to analysis. The ashing techniques obviously require considerably more time than would a direct method. The time factor becomes very significant when several thousand samples are processed. The time factor, therefore, was of major consideration in the development of this technique, which is adaptable to large numbers of samples.
