TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 Decision of the Executive Body concerning the establishment a Task Force on the Hemispheric Transport of Air Pollution The functions of the Task Force will be to: develop a fuller understanding of the hemispheric transport of air pollution estimate the hemispheric transport of specific air pollutants for the use in reviews of protocols to the Convention EMEP/MSC-E

TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 The first meeting of the Task Force on Hemispheric Transport of Air Pollution (Brussels, 1-3 June, 2005) Overview of the state of the science TF HTAP Policy-Relevant Science (Questions) How does the intercontinental or hemispheric transport of air pollutants affect air pollution concentration or deposition levels in the Northern Hemisphere for ozone, PM, acidification and eutrophication; Hg; and POPs ? What processes need to be better understood to describe the relative significance of intercontinental transport ? What fraction of measured pollutant concentrations or deposition levels is due to emissions from each of the other countries in the Northern Hemisphere? . . . EMEP/MSC-E

TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 Conclusions The input of hemispheric sources to the contamination of European region is considerable for Hg and some POPs. External anthropogenic and re-emission sources is of importance for evaluation of source-receptor relationships for Hg and POPs in Europe. Compatibility of model input data for hemispheric and regional modelling should be under consideration. Close co-operation with and joint meeting of TFMM and TFHTAP on scientific and technical issues is highly appreciated. Переделать EMEP/MSC-E
