Foreword
This document (CEN/TR 14589) has been prepared by Technical Committee CEN/TC 292 "Characterization of
waste", the secretariat of which is held by NEN.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
Speciation is one of the growing features of analytical chemistry of the last years. It is now recognized that the
determination of total trace element contents is no longer sufficient, because the biological and environmental
impact of an element is dictated by the physico-chemical form in which it is present in the sample.
Chromium belongs to the category of problematic elements in analytical chemistry, because it behaves as a
valence chameleon. The chemistry of chromium compounds is rather complicated, inorganic chromium compounds
may occur in oxidation states ranging from -II to +VI [1,2]. However, in natural systems, Cr(III) and Cr(VI) are the
most stable forms. Besides Cr(III) which is an essential trace element for mammals, including man, Cr(VI)
compounds are genotoxic and potentially carcinogenic in humans. Evidence exists for the carcinogenity of calcium,
strontium and zinc chromate [2,3]. The inoffensive nature of Cr(III) ion
