Pesticides - rare residues - in apple

P2716-RT puts the spotlight on the outsiders which are permitted in theory, but rarely detected in practice. Low experience with those pesticides in routine is the analytical challenge to overcome in this ring test.

The scope of pesticides is mentioned below. 6 to 10 active substances are spiked.

The analytical data are assessed with respect to

the comparability (z-score), and
the trueness (70 to 120% of the spiked level, as far as applicable).
