Abstract A set of test materials of the green alga Chlorella vulgaris with different levels of naturally bound Cd and about the same levels of other 13 essential or trace elements (BIOMA 1–4) was produced for proficiency testing of laboratories involved in elemental analysis of food. Criteria of the laboratories’ performance, such as the z-score and combination scores RSZ and SSZ were evaluated and discussed in terms of their suitability for proficiency testing using a set of test materials with the same matrix. The use of the test materials as a set of internal reference materials has also been suggested.
