  9. The CORINAIR 1990 Inventory covers 11 main source sectors (as agreed with EMEP)(McInnes, 1996) • Public power, cogeneration and district heating plants • Commercial, institutional and residential combustion plants • Industrial combustion • Production processes • Extraction and distribution of fossil fuels • Solvent use • Road transport • Other mobile sources and machinery • Waste treatment and disposal • Agriculture • Nature Point – Area – Line Sources Completeness Consistency Transparency

  14. Biogenic Emissions • Isoprene (2-methyl-1, 3 –butadiene, C5H8) – most abundant of BVOCs. – oak, pine, spruce, sweetgum, eucalyptus, and aspen – light and temperature dependent – isoprene is removed through reactions with O3, OH, and NO3 • Monoterpenes (C10H16) – spruce and fir are large sources – temperature dependent • NO – emitted from soil – soil temperature and moisture dependent • OVOCs

  15. For forests, grasslands and other vegetation, an appropriate system describing the emissions flux of NMVOC species, is based on Guenther [1997]: • Flux (μg m-2 yr-1) = ∫ ε D γ dt εis the average emission potential (μg g-1 h-1) for any particular species D is the foliar biomass density (g dry weight foliage m-2) γis a unit-less environmental correction factor

  16. BVOCs play a significant role in the Troposphere chemistry • The hydrocarbons isoprene and several monoterpenes (α-pinene, β-pinene, limonene, etc.) are generally considered the most important compounds for regional ozone formation in Europe (Simpson, 1995; Stockwell et al., 1997). • Some of the VOCs from biogenic sources, such as monoterpenes, can be oxidized by hydroxyl radicals (OH), nitrate radicals (NO3) and ozone (O3), and directly take part in the secondary organic aerosol (SOA) formation processes.

  23. a study of this magnitude for Turkey had never been carried out before emission modeling alone has been the most challenging task a significant impact of European emissions to PM10 concentrations in Istanbul has been demonstrated to be 50% in this study, the first task has been carried out in a comprehensive approach for the long-range PM10 transport, but plenty of sensitivity analyses should be performed for other pollutants in an ensemble way of thinking observation network system Anthropogenic / natural emissions an emission processing strategy should be developed considering national characteristics This emission inventory and emission modeling processes should match and be made suitable for the current studies and technologies in Europe evaluation should be researched for a long period of time CONCLUSIONS AND FUTURE STUDIES
