Abstract: This report presents the results of an ILC which focussed on the determination of total As, Cd, Pb , and Hg, as well as methylmercury and inorganic arsenic in seafood. The test material used in this exercise was the Certified Reference Material (CRM) DOLT-4, dogfish liver of the National Research Council of Canada (NRC). Each participant received one bottle containing approximately 20 g of test material. Fifty-seven laboratories from 29 countries registered to the exercise and all of them reported results. The assigned values and their associate uncertainties for total As, Cd, Pb, Hg and Methylmercury are the certified values taken from the DOLT-4 certificate. An attempt was made to establish an assigned value for inorganic As (iAs) using the results provided by a group of five laboratories expert in the field. Unfortunately, contrary to what was expected, the results obtained by the expert laboratories for iAs showed a large spread and no assigned value could be established.
