Regional and Extra-regional Contribution to Hg

13 April 2021 @ 11:00 15:00 UTC

The focus of the two April workshops will be on improving our ability to estimate the contribution of regional and extra-regional sources to long-term trends in Hg, POPs, and other chemicals of emerging concern.  In the workshops, we will:

  • Anticipate assessment needs of the LRTAP, Minamata, and Stockholm Conventions
  • Review progress made in other forums, including recent AMAP assessments. 
    • Identify cooperative activities that can be undertaken in the short term (2 years) and longer term (4-5 years) to improve our understanding and ability to estimate source contributions.

The 13 April workshop will focus on Hg, and the 15 April workshop will focus on POPs and other chemicals of emerging concern.

Follow up meetings will be scheduled to further organize cooperative activities identified in the workshops.
