This report describes the additional certification of Pb in BCR-320R (channel sediment). This material has already been certified for its total trace element content (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni Sc, Th, Tl, U, V and Zn. Indicative values have been established for Se and Sn).
Difficulties with the characterisation of Pb made an additional certification necessary. During the first characterisation exercise in 2002, a result for Pb obtained by one of the participating laboratories significantly differed from the rest, but no reasons were found to reject the result obtained. Therefore a decision was taken to use completely different laboratories for the present characterisation.
