1. Fine particles: the views of the WG on Strategies and Review Richard Ballaman Chairman of WGSR Swiss Agency for the Environment, Forests and Landscape

2. 2/10

3. 3/10 Tasks for the EG on PM Assess the degree of control provided by existing protocols; Review current work on PM under CLRTAP, taking also into account the forthcoming Thematic Strategy of EC; Review the characteristics of PM as transboundary pollutant (i.a. contribution from different sources or scale, implication of choosing different particle size fractions); Consider the scientific and technical requirements, as well as non-technical measures, needed for possible option on how to develop further measures to reduce PM.

4. Acidification Eutrophication Tropospheric ozone Multi pollutants / multi effects approach with new pollutants and driving forces SO 2 NH 3 NO x NMVOC Particulate matter Population exposure primary PM Heavy Metals PAH

7. 7/10

8. 8/10 Source categories to further consider Ships, diesel vehicles, off-road sector Industrial processes Small combustion (wood burning) Agriculture (animal housing, manure storage and spreading) Retrofitting of existing sources

9. 9/10 Options to be considered by WGSR Secondary PM are already covered by the MP- ME Gothenburg protocol and Primary PM could also be integrated in MP-ME. Primary PM are already partially covered by protocols on HMs which may be further developped in a Protocol on mercury and PM (including HMs) A specific protocol on primary PM.

10. 10/10 Expert views are welcomed on: Which option looks more promising ? (advantages / disadvantages) Are the necessary information on PM emission inventories and projections accurate enough to allow emission ceilings? Do we have sufficient data to define BAT and LV for primary PM?

11. 11/10 Challenges for the Convention LRTAP Increase life expectancy of European population by decrease of the mean population exposure to PM2.5 Implementation of a legal instrument to abate PM emissions (ideally with commitments of 48 countries).
