Intercalibration of Analytical Methods on Marine Environmental Samples. Trace Element Measurements on Fish Homogenate (MA-B-3/TM).

摘要

The pollution of the seas by various chemical substances constitutes nowadays one of the principal concerns of mankind. The International Atomic Energy Agency has organized in past years several intercomparison exercises in the framework of its Analytical Quality Control Service. The present intercomparison had a double aim: first, to give laboratories participating in this intercomparison an opportunity for checking their analytical performance. Secondly, to produce on the basis of the results of this intercomparison a reference material made of fish tissue which would be accurately certified with respect to many trace elements. Such a material could be used by analytical chemists to check the validity of new analytical procedures. In total, 53 laboratories from 29 countries reported results (585 laboratory means for 48 elements). 5 refs, 52 tabs. (Atomindex citation 20:018527)
