9/15 The protocol on Heavy Metals Annex III BAT for controlling emissions of HMs from 11 stationary source categories. Annex V with limit values for controlling (mainly particulate) emissions from major stationary sources. Annex VI with product control measures (e.g. lead free gasoline, batteries) On-going work by IFARE to review technical annexes and by TNO to explore further measures

10/15 The Protocol on Persistent Organic Pollutants Annex IV with limit values for PCDD/F from waste incineration. Annex V with BAT to control emissions of POPs from major stationary sources Annex VII with recommended control measures for reducing emissions of POPs (i.a. mass of particulates and PAH) from mobile sources. On-going work by TNO to explore further measures

11/15 Options to consider by WGSR Secondary PM are already covered by the MP- ME Gothenburg protocol Primary PM to be integrated Protocol on mercury and PM (including HMs) A single protocol on PM

12/15 Open questions Which option seems more promising (advantages / disadvantages) ? Are the necessary information on PM emission inventories and projections accurately enough to allow emission ceilings? Do we have sufficient data to define BAT and LV for primary PM?

14/15 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 for 48 countries).
