SPECIEUROPE: The European data base for PM source profiles

Özet

A new database of atmospheric particulate matter emission source profiles in Europe (SPECIEUROPE)developed in the framework of the Forum for air quality modeling in Europe (FAIRMODE, Working Group3) is accessible at the website http://source-apportionment.jrc.ec.europa.eu/Specieurope/index.aspx. Itcontains the chemical composition of particulate matter emission sources reported in the scientificliterature and reports drafted by competent authorities. The first release of SPECIEUROPE consists of 151measured (original), 13 composite (merging different subcategories of similar sources), 6 calculated(from stoichiometric composition) and 39 derived (results of source apportionment studies) profiles.Each profile is related to one or more source categories or subcategories. The sources with the highest PMrelative mass toxic pollutants such as PAHs are fuel oil burning, ship emissions, coke burning and woodburning. Heavy metals are most abundant in metal processing activities while halogens are mostlypresent in fertilizer production, coal burning and metallurgic sector. Anhydrosugars are only measured inbiomass and wood burning source categories, because are markers for these categories. The alkalineearth metals are mostly present in road dust, cement production, soil dust and sometimes coal burning.Source categories like traffic and industrial, which contain heterogeneous subcategories, show thegreatest internal variability.The relationships between sources profiles were also explored using a cluster analysis approach basedupon the Standardized Identity Distance (SID) indicator. The majority of profiles are allocated in 8 majorclusters. Some of the clusters include profiles mainly from one source category (e.g. wood burning) whileothers, such as industrial source profiles, are more heterogeneous and spread over three differentclusters.
