FRENCH PM WORK IN PROGRESS With the contribution of: Sonia Babu, Jean-Pierre Chang, Carole Levy, Bénédicte Oudart, Emanuel Rivière Jean-Pierre Fontelle
2
PM INVENTORY Previous inventory : (before mid 90s) TSP only New inventory : (supported by the French Ministry of Environment ) Geographical area : France Limited number of sources TSP, PM10, PM2.5, PM1.0 (primary sources) Annual time series from 1990 to 1998 200 types of sources : all defined in SNAP 97+ additional sources
3
SECTORS CONSIDERED road transport : exhaust, brake, tyre and clutch wear. other mobile sources : air traffic, railways, inland waterways, sea transport, machinery, household and gardening. Stationary sources : Agriculture Nature Waste incineration Mobile sources : Combustion – industrial and non industrial
4
COMPARISON WITH OTHER COUNTRIES Goal : to complete and to validate the French PM inventory total emissions Observations : high discrepancies in emissions by sectors emission factors source coverage methodologies
5
Industrial processes : SECTORS CONSIDERED iron and steel industries, cement, lime, plaster, glass production, road paving, bricks and tiles, fine ceramic materials, non-ferrous metal industries, aluminium, lead and zinc, adipic acid, chipboard, sugar and flour production, storage and transport of cereals, etc...
6
RESULTS IN BRIEF
7
TEACHINGS Problem in defining the inventory fields (eg : resuspension ?) Not complete (missing sources) Lack of knowledge (missing and obsolete data) Data from foreign studies possibly misused Large discrepancies between various sources of information Extremely high uncertainty
8
COMPARISON OF INVENTORIES Comparison between TNO (edit.1997), IIASA (edit.2000) results and other national inventories * related to a limited number of sources (35% of sources considered for TSP)
9
SOME EXAMPLES Combust. in manufac. industry : combustion plants > 50MW Combustion in households : EF TSP (g/GJ) Heavy fuel oil Wood CITEPA 35 15 OFEFP/ BUWAL 23 80 EF wood (g/GJ) TSP PM10 CITEPA 500 175 OFEFP / BUWAL 150 ITALY 1560 IIASA 150 EPA 870
10
SOME EXAMPLES District heating plants : combustion plants < 50MW Aluminium production (electrolysis) : EF TSP (g/GJ) Coal CITEPA 100 OFEFP / BUWAL 50 EF (kg/t) TSP PM10 CITEPA 9 5 OFEFP / BUWAL 2 ITALY 1 IIASA(uncontrolled)25 TNO (Eastern Europe) 7 TNO (Western Europe) 3
11
SOME EXAMPLES Road transport : gasoline diesel oil EF mg/km PC LD Moto. HD CITEPA highway 11 13 7 525 TSP rural 12 146 634 urban 21 207 1141 Total6 650 IIASA 4-stroke55 970 PM10 2-stroke 610
12
EXAMPLES OF DIFFERENCES IN SOURCE COVERAGE NB : 1990 TSP mass emissions are indicated in ( ) % refer to TSP
13
NEED FOR ADDITIONAL SOURCES Sugar production Charcoal manufacture Conclusion : SNAP and other nomenclatures to be revised ? Flour production Fireworks Explosives production Wood work Cereals handling Smoking meat Shoe’s sole wear Smoking Tilling of arable land crops Construction Road abrasion Quarrying Harvesting Use of BBQ
14
OBSERVATIONS From discussion between experts : limited knowledge in most countries very limited number of available inventories need for more monitoring campaigns fugitive emissions much more complex to estimate and probably represent a significant amount of total emissions stress politicians on the high level of uncertainties and risk to use irrelevant information when elaborating regulation involving high economic impact
15
CONCLUSION French inventory to complete and to improve Further French work : Need for exchange of knowledge between experts, initiatives for cooperation is welcome, especially regarding transparency of data As primary sources represent a minor part of total PM, would it not more efficient to focus essentially on secondary sources ? Need to consolidate PM inventories before use by policy makers Revision of the French Inventory in 2001 by CITEPA Comparison study on methodology used by different countries to carry out PM inventories (final report expected for September 2001) by CITEPA Projection study, 2015-2020 (expected for October 2001) by CITEPA and INERIS
