Determination of total As, Cd, Pb, Hg, MeHg and iAs in fish
The EURL-HM-22 proficiency test (PT) focuses on the determination of the mass fraction of total arsenic, cadmium, lead, mercury, methylmercury and inorganic arsenic in fish. This PT is organised in support to Commission Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs.
The main objective of this exercise is to assess the analytical capabilities of nominated the National Reference Laboratories (NRLs) in the determination of the specific toxic trace elements in fish.
Participation in EURL-HM-22 is open ONLY to NRLs and obligatory for those having mandate for this type of analysis.
Participation is free of charge.
Test materials and analytes
The test material to be analysed is fish. Each participant will receive one test item. The measurands are total As, Cd, Pb, Hg, MeHg and iAs in fish.
General outline of the exercise
Participants are requested to perform one to three independent analyses using the method of their choice, and to report the mean of their measurement results, the associated expanded measurement uncertainty and coverage factor k.
Detailed instructions will be sent together with the test item.
