摘要：

Tuna fishes were collected in the Straits of Messina (Italy), were dissected and dorsal muscles minced, freeze-dried, ground and sieved. The obtained powder was stabilised by gamma-irradiation and filled into brown glass bottles. The homogeneity and stability at +20 degrees C and +40 degrees C were verified with regards to the total arsenic, dimethylarsinic acid and arsenobetaine contents. Ten laboratories participated in the certification study. All participants had demonstrated beforehand their ability to produce accurate results for the As speciation in fish tissue. The certified values are: total arsenic (4.8 +/- 0.3) mg/kg, arsenobetaine (52 +/- 3) mu mol/kg, dimethylarsinic acid (2.0 +/- 0.3) mu mol/kg. The material is available from the BCR since early 1998.
