Spatially distributed emissions in 2015       Source Global Mercury Assessment 2018


A global understanding of major process  and mechanisms effecting the dynamics of mercury in the atmosphere and and at the interfaces with other ecosystems is important for setting and implementing strategies on mercury both and at global and local levels.

Integrated and updated global assessments, based on reliable information from regional and national levels, are essential for improving global understanding of mercury and for predicting trends.

More on mercury air transport and fate research


The objective of the Partnership Area is to increase global understanding of international mercury emissions sources, fate and transport.


To meet its objective, the Partnership Area puts priority on the following actions:

  • Accelerating the development of sound scientific information in global  mercury cycling and its patterns
  • Enhancing compilation and sharing of such information among various stakeholders
  • Providing technical assistance and training
  • Enhancing the development of a globally-coordinated mercury observation system  including air and water ecosystems
  • Enhancing the exchange of information and cooperation with relevant international organizations, groups and programmes
