Abstract

In 1987 the Community Bureau of Reference (BCR) initiated a collaborative study in order to improve the determination of organic mercury in environmental samples. The object of the study was to make it feasible within the EEC to control the content of methyl-mercury (e.g. in fish) and to elucidate the different pathways of organic mercury in nature. The final goal of the study was to produce and certify different environmental reference materials for the content of different mercury species. The work focussed on methyl-mercury and an approach was selected starting with tests of the detection and calibration methods and ending with tests of the extraction procedures and analysis of a real sample. 7 different samples were tested. Results are presented for synthetic solutions and raw and cleaned extracts of a fish sample including a spiked extract. Systematic errors between laboratories are demonstrated. The study also reveals the lack of suitable capillary columns and problems in the use of internal standards.
