Analyses of estuarine water are performed routinely by a number of organisations to monitor the level of contamination by toxic compounds, such as trace metals. In order to improve and control the quality of such determinations, the Measurements and Testing programme of the European Commission has organised two interlaboratory studies which allowed the detection and removal of most of the pitfalls observed in the determination of a series of eight elements, namely 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 interlaboratory studies carried out prior to the certification campaign.
