Exposure scenarios and exposure factors

Consumer exposure to chemical substances

Exposure factors are actions and media that bring us in contact with environmental agents. Important exposure factors are for instance consumption of food and beverages, housing conditions, time use in micro-environments, but also inhalation rates and consumer products use. Also activities of people contribute to the exposure to environmental agents.
Two major initiatives are mentioned that describe exposure factors for the European as well as the American population in the navigation section on the left.

ConsExpo Factsheets

The ConsExpo factsheets give important information for the consistent estimation and assessment of the exposure to, and the uptake of, substances from consumer products. Exposure factors are included in these documents.

European Exposure Factors (ExpoFacts) Sourcebook

The European Exposure Factors (ExpoFacts) Sourcebook is a collection of statistics and references and contains data from 30 European countries: Austria, Belgium, Bulgaria, 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. 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.

US-EPA Exposure Factors Handbook

The US-EPA also has made a summary of the available statistical data on various factors used in assessing human exposure. These factors concern the general (US) population as well as various segments of the population who may have characteristics different from the general population. Specific data for children are included in the latest version of the report. (US-EPA, Exposure Factors Handbook (2011) Final Report)

US-EPA Consolidated Human Activity Database (CHAD)

The American Consolidated Human Activity Database (CHAD) contains data obtained from pre-existing human activity studies that were collected at city, state, and national levels. CHAD is intended to be an input file for exposure/intake dose modelling and/or statistical analysis. CHAD is a master database providing access to other human activity databases using a consistent format.
