Title: Establishing International Comparability of Measurements
of Trace Elements in Natural Water (IMEP-6)
Series: International Measurement Evaluation Programmes
Coordinator(s): A.
Lamberty and J.R.
Moody
Remarks: Division V and Section VII.C
Completion Date: 1998 - Project Completed
Objective:
The measurement of water quality is of paramount importance to
human health. Despite being a theoretically easy matrix to analyze,
water analyses are often in wide disagreement among laboratories.
The IMEP-6 programme examined water analytical data quality on a global
scale using certified test samples with reference values determined
by a primary method of measurement (isotope dilution mass spectrometry).
Progress:
More than 150 participants were involve in the programme. The
reference values for 14 elements in natural and artificial water were
established by the cooperation of 4 national laboratories in 3 countries.
