Project Details


Arsenic exists in many different chemical forms in the marine environment, of which the water-soluble arsenicals are well studied. However, knowledge regarding the socalled arsenolipids (lipid soluble arsenic compounds) is so far limited, although arsenolipids are present in considerable quantities in fish oil (reported concentrations range from 4 to 15 mg As/kg).
The present project aims to generate knowledge on arsenolipids in fish oil and other marine samples, with a main aim of developing methods for the determination of arsenolipids in marine samples using capillary HPLC-ICPMS and capillary HPLC-ESI MS/MS.
The results obtained within the project will be of importance to national and international food authorities in their evaluation and risk assessment of the consequences of arsenolipids for food safety and fish welfare. Furthermore, the results will also be of value for the aquaculture industry and the fishery sector.
