Fish Homogenate ( Methyl Mercury) (under recertification)

Temp. out of sales, proposed alternative is IAEA-476

The fish material was collected in 1999 from the North Sea. Most of what was collected was herring, but the sample material also contained capelan and anchovy. It was deep-frozen, freeze-dried, triple-extracted with acetone to remove fat, and then ground and sieved. The particle size fraction <250 µm was homogenized by mixing in a rotating glass bottle for 15 days.
