Mercury in its many chemical forms is highly toxic to human, animal and environmental health. It occurs naturally in the environment, and in addition human activity has increased mercury levels over the last 100 years.
In order to prevent the global environmental pollution and damage to health caused by mercury, a new global and legally binding convention aimed at reducing global mercury emissions, the Minamata Convention, was signed and agreed by 185 countries in 2013.
European Directives on mercury require the enforcement of target values for mercury in the environment. This project developed new traceable measurements and the measurement infrastructure needed to support EU legislation and the global convention aimed at reducing global mercury emissions.
