Promoting the implementation of the Minamata Convention on Mercury

Laboratory proficiency testing for mercury

In countries that see mercury-caused environmental pollution emerge, there is a growing need for capacity development regarding appropriate mercury monitoring and health impact surveys to implement provisions of the Convention. In efforts to address this situation, we, jointly with the UN Environment Programme Regional Office for Asia and the Pacific (UNEP ROAP), administer analysis proficiency testing for mercury with the view to further establishing the accuracy of analysis results in the signatory countries.

Objective of analysis proficiency testing for mercury

To assess the individual level of proficiency of a testing laboratory that performs mercury analysis in order to deliver better mercury monitoring skills.

Testing laboratories eligible for proficiency testing

Public research institutions and universities, etc. that engage (or are planning to engage) in mercury analysis for monitoring or research purposes.
