title: Application of pulse polarography with anodic stripping voltammetry to biological and toxicological analyses for lead and cadmium.
abstract: The development of polarographic techniques within the last thirty years has made possible exceptional increases in sensitivity ; thus the order of concentration studied has passed from 10-3 g ion/1. to 10-10 g ion/1. Pulse polarography with anodic stripping voltammetry is, therefore, particularly suitable for the determination of a large number of the so-called " biologically  essential " and " highly toxic " metals, more often than not present in extremely low concentrations in biological samples which may be of limited volume (blood, for example). Our principal concern has been to describe and apply a method for the determination of lead and cadmium, sufficiently sensitive, precise, practical and rapid for everyday use by biologists and toxicologists. A fortiori this method is applicable in hydrology to the determination of traces of these metals in water.
