  1. Emissions Inventory MATES III Technical Advisory Group March 13, 2008

  2. Outline • Methods • Results for carcinogens � Species apportionment � Source apportionment � Emissions and air quality changes since MATES-II

  3. Methods • 2007 AQMP inventory forms the basis of the MATES-III toxic inventory. • 2002 baseline emissions projected to 2005. • “Top-down” approach used for developing toxic emissions. – i.e., chemical composition of TOG and PM emissions determined by ARB’s speciation profiles. – http://www.arb.ca.gov/ei/speciate/speciate.htm. • Emissions spatially allocated to 2 km by 2 km grid cells.

  4. Why “Top-down Approach? • Speciating TOG and PM inventories affords consistency with 2007 AQMP. – Fits in with AQMD’s goal of a comprehensive plan • Photochemical modeling requires complete speciation of TOG; an inventory of just toxics would be insufficient. • AQMP tools for projecting future emissions & air quality benefits can also be used for MATES-III to estimate cancer risk benefits from the AQMP.

  5. Pollutants Inventoried Acetaldehyde* Elemental carbon Organic carbon Acetone Ethylene dibromide* p-Dichlorobenzene* Arsenic* Ethylene dichloride* Perchloroethylene* Benzene* Ethylene oxide* Propylene oxide* 1,3 Butadiene* Formaldehyde* Selenium Cadmium* Hexavalent chromium* Silicon Carbon tetrachloride* Lead* Styrene Chloroform* Methyl ethyl ketone Toluene Chromium Methylene chloride* Trichloroethylene* 1,1 Dichloroethane* MTBE* Vinyl chloride* Diesel particulate* Naphthalene* 1,4 Dioxane* Nickel* * denotes carcinogen

  6. Emission Inventory Results

  7. Preliminaries • Slides that follow only consider carcinogens. • Emissions are in diesel PM currency. – i.e., emissions weighted by the ratio of the carcinogen’s cancer potency to the cancer potency of diesel PM. • 1998 = MATES-II; 2005 = MATES-III

  8. Species Apportionment of Cancer Potency Weighted Emissions Contribution Contribution Toxic Toxic (%) (%) Diesel particulate 86.94 Arsenic 0.66 1,3-Butadiene 4.02 p-dichlorobenzene 0.30 Benzene 2.95 Cadmium 0.29 Perchloroethylene 2.92 Hexavalent chromium 0.26 Formaldehyde 0.97 Naphthalene 0.24 Total 99.6

  9. Carcinogenic Source Apportionment Area Point 5% 2% On-road 36% On-road Off-road Point Area Off-road 57%
