Interlaboratory exercise for improving the quality of trace element determinations in estuarine waterFunded under: FP2-BCR 4
Analyses of estuarine water are routinely performed by a number of organisations to monitor the level of contamination by toxic compounds. To improve and control the quality of such determinations, the BCR has organised an interlaboratory exercise to detect and eliminate most of the pitfalls observed in the determination of the series of nine elements, As, Cd, Co, Cu, Fe, Pb, Mn, Ni and Zn. This work enabled the feasibility of preparation of candidate estuarine water certified reference materials (CRMs) to be tested. The materials used in the exercise were collected in Portugal (Tagus estuary). They were carefully prepared and their homogeneity and stability were verified. This paper presents the main results of the intercomparison.
