The European Exposure Factors (ExpoFacts) Sourcebook is a collection of statistics and references. It is primarily aimed at being a tool for environmental exposure analysis and risk assessment but it can also serve as a data source for administration, NGO's and anyone interested in European statistics.The ExpoFacts Sourcebook has three parts: a database, a reference guide, and a document library. All of these are free to use, and available through this site.The ExpoFacts Sourcebook contains data from 31 European countries: Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, The Netherlands, Norway, Poland, Portugal, Romania, the Slovak Republic, Slovenia, Spain, Sweden, Switzerland and United Kingdom.The actions and the media that bring us in contact with environmental agents are called exposure factors. Important exposure factors are e.g. housing conditions, consumption of food and beverages, and time use in different microenvironments. The European exposure factor data have traditionally been scattered around national and international institutes, in scientific articles and reports. This data has now been compiled to the extent possible into this ExpoFacts database, so that it would be easily accessible for all of those who need it.The ExpoFacts database contains a large selection of population data to make the database a better tool for exposure and risk analysis. The age pyramids, socio-economic distributions etc. enable the exposure analyst to extrapolate the results of e.g. concentration or exposure surveys to wider populations.The ExpoFacts project was funded in 2002-2006 by CEFIC - LRI contract No NMALRI-C1.5KTL-0207 and LRI-C1.5.1-KTLE-0512. Since January 15th 2007, it is hosted by the PCE Unit at the Joint Research Centre of the European Commission in Ispra.ExpoFacts DatabaseThe ExpoFacts database contains European exposure factor data, collected from more than one hundred national and international data sources; databases, reports, scientific articles etc. This data is now combined and made easily and freely available in the form of this database.The nearly one hundred data tables available in ExpoFacts database are classified under seven main titles, to make table browsing easier and faster. Also there is a possibility to filter the data according to preferences, e.g. by choosing just the countries of interest, so that the eventually printed or downloaded data tables are in a more convenient form for future use.Even though the ExpoFacts database is built primarily as a tool for environmental exposure and risk assessment, it contains information that might be interesting also for users from many other backgrounds e.g. administration, NGOs and education sector.The database contains data that are available uniformly for all or most countries, there are data that are representative of just one or few countries, and there are data that present just a particular subpopulation. This, and all other data quality issues should be kept in mind when using the data available in this database, and especially when comparing various data. Most data are not directly comparable.Access the databaseContactVittorio ReinaJRC-F2-DATAec [dot] europa [dot] eu (JRC-F2-DATA[at]ec[dot]europa[dot]eu)European Commission, Joint Research Centre,Directorate F – Health, Consumers and Reference MaterialsI-21027 Ispra (VA) Italy
