IMEP-39

Total Cd, Pb, As, Hg and inorganic As in mushrooms

The IMEP-39 interlaboratory comparison (ILC) exercise focuses on the analysis of total cadmium, lead, arsenic, mercury and inorganic arsenic in mushrooms. This ILC is organised in the frame of EU Regulation 1881:2006 and contributes to the implementation of high quality and uniform analytical results, on the determination of heavy metals in mushrooms. It is therefore a proficiency test (PT).

This PT exercise runs in parallel to IMEP-116 where only appointed National Reference Laboratories can take part in.

IMEP-39 PT exercise is open to all laboratories.

The cost of this interlaboratory comparison is 350 € per registration.

Test materials and analytes

The test material to be analysed is freeze dried mushrooms contained in a glass bottle. Each participant will receive one bottle. The measurands are total Cd, Pb, As, Hg and inorganic As in mushrooms.

General outline of the exercise

Participants are requested to perform 1 - 3 independent analyses using the method of their choice, and to report their result for the PT assessment, its associated measurement uncertainty and coverage factor k.
Detailed instructions will be sent together with the sample.
