Proficiency test on heavy metals in food supplements
The Community Reference Laboratory for Heavy Metals in Feed and Food in the frame of Commission Regulation (EC) No 1881/2006, and contributing to the implementation of high quality and uniform analytical results, organised a proficiency test on the determination of total Cd, Pb, As and Hg in food supplements.
The main objective of this exercise was to evaluate the capabilities of the nominated national reference laboratories in the determination of heavy metals according to Commission Regulation (EC) No 1881/2006.
Only appointed national reference laboratories could participate in this exercise.
