Abstract

The wide variation in chemical trace measurements was first brought to my attention by Prof. De Bievre at the 1998 meeting of the Committee on Chemistry and Industry (COCI) in Johannesburg, South Africa. During our 1999 meeting in Berlin, Germany, he again presented data demonstrating a huge (5O%) variation in trace element (Pb, Cd, Fe, and Zn) concentrations in water even from "accredited" laboratories. Similar problems were demonstrated for analysis of catalyst metals (Pt) in car exhaust material. Because such data are increasingly used in decision-making areas of industrial concern, our committee adopted. "Reliability of Chemical Measurements" as a new, formal project with Prof. De Bievre as coordinator. Interest was immediately demonstrated by UNESCO (Dr. A. Pokrovsky), and cooperative information dissemination efforts began.

Although a brief summary of the concerns, "Metrology in Chemistry", had been published in chemistry and Engineering News (C&EN, 31 May 1999, p. 29), COCI encouraged Prof. De Bievre to submit a more detailed summary to Chemistry International (CI). This article provides "snapshot" pictures of chemical measurement (un) reliability, with many practical, societal implications. .
