Interlaboratory exercise for improving the quality of trace element determinations in estuarine waterFunded under: FP3-MAT
Analyses of estuarine water are routinely performed by a number of organisations to monitor the level of contamination by toxic compounds such as trace metals. To improve and control the quality of these determinations, the Community Bureau of Reference (BCR) has organised an interlaboratory exercise to detect and remove most of the pitfalls observed in the determination of a series of 9 elements, namely 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 this 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.
