Proficiency test on heavy metals in feed of plant origin
The Community Reference Laboratory for Heavy Metals in Feed and Food in the
frame of Directive 2002/32/EC, and contributing to the implementation of high
quality and uniform analytical results, has organised a proficiency test on
the determination of total As, Cd, Pb, Hg, Sn and extractable Cd and Pb in
feed of plant origin.
The main objective of this exercise was to evaluate the capabilities of
nominated national reference laboratories in the determination of heavy metals
according to Directive 2002/32/EC.
Only appointed national reference laboratories could participate in this
exercise.
Test materials and analytes
The test material to be analysed was feed of plant origin. One
bottle/participant was sent to the participants in October 2009. The
measurands were total As, Cd, Pb, Hg, Sn extractable Cd and Pb according to
Directive 2002/32/EC.
General outline of the exercise
Participants were requested to perform two or three independent analyses using
the method of their choice for the determination of total As, Cd, Pb, Hg, Sn
and using a method agreed upon at the 2nd Workshop organised by the CRL for
the determination of extractable Cd and Pb.
