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

The IMEP-116 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, which sets maximum levels for certain contaminants in foodstuffs and contributes to the implementation of high quality and uniform analytical results.
The main objective of this exercise is to evaluate the capabilities of nominated National Reference Laboratories (NRLs) in the determination of heavy metals in mushrooms, which maximum limits are set according to EU Regulation 1881:2006. It is therefore a proficiency test (PT).
Participation in IMEP-116 is mandatory for all NRLs having experience in this kind of analysis.

Only appointed NRLs can participate in this exercise.

Registration is free of charge.

Test materials and analytes

The test material to be analysed is freeze dried mushroom contained in a glass bottle. Each participant will receive one bottle of the test item.
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 test sample.

Reporting of results: Deadline 15/06/2013
