A GIS based anthropogenic PM10 emission inventory for Greece

An anthropogenic, chemically speciated PM10 emission inventory was compiled for Greece in 10 km spatial resolution. The inventory comprises of all anthropogenic particulate matter sources and it was compiled using a Geographical Information System (GIS) integrated with SQL programming language. Input data from the national and international databases were used for the calculation of spatially and temporally resolved emissions for the road transport and all the subsectors of the other mobile sources and machinery sector using top–down or bottom–up methodologies. Annual data from existing emission databases were also used and were temporally and spatially disaggregated using source relevant statistical data and high resolution maps. The sectoral emission totals are compared with other emission databases or studies conducted in the area. Total anthropogenic emissions in Greece were estimated to be 182 219 t for the base year 2003. The results indicate the industrial sector as the major PM10 emission source (39.9% contribution) with the major industrial units though to be situated inside the organised industrial areas of the country. The power generation sector (21.4%) is the second largest contributor in national level mostly derived from one specific industrial region at north. International cargo shipping activities (9.6%) is also an important source category for particles. Heat production and road transport are found to play a significant role inside the urban centres of the country.
