INTERA Indoor exposure knowledge management system

Intera

Scope

Indoor exposure knowledge management system (KMS) that incorporates as much as possible of the information needed in exposure assessments related to indoor environments and provides a user-friendly access to that information through this interface. The knowledge management system accommodates the data produced in the previous studies and allows powerful way to utilize the information already available. All content can be updated by anyone providing the possibility to spread the available and newly produced information fast and easily among the various target groups in the field.

The work has been done in a project called INTERA (Integrated Exposure For Risk Assessment In Indoor Environments), which is sponsored by the CEFIC LRI. More information of the project is available in the project web-pages.

Work in progress

The indoor exposure knowledge management system includes links to available data, tools and documents and also provides some processed information that has not been available in a form of a database earlier. The content collected to this page is under the following disclaimer.

Data Exposure concentrations for indoor exposure This group of data includes information on measured concentrations in indoor and outdoor air. In addition data for concentrations in consumer products and measured personal exposure levels and biomonitoring data are provided. This kind of data can be used for predicting the personal exposure levels resulting from indoor exposure. Sources and source strengths of indoor air pollutants Housing, sociological conditions and physiology determining exposures This group of data includes information on housing, such as floor area and volume, air exchange rates, habitant information, building materials etc.). This information can be used to determine the exposure levels of pollutants for cases when measured information is not available or cannot be modeled due to lack of data. Housing statistics Air exchange rate for European residences Human physiological factors Exposure modifiers This group of data includes information on exposure modifiers and this kind of data can be used to describe the features that affect to the level of exposure indoors. consumer behaviour indoor:outdoor ratio

Modelling tools This group includes the modeling tools that can be used for evaluating the levels of indoor exposure. Models can be used for calculating source emissions, concentrations and/or exposure levels. Indoor exposure models

Documents This section provides documents relevant for indoor exposure. Guidance documents General guidance on exposure assessment Guidance documents for consumer products Project documents EnVIE report - Indoor Air Pollution Exposure. The indoor exposure agents reviewed in this report include those, originally selected for EnVIE, namely tobacco smoke, (combustion) particles, carbon monoxide, radon, moisture, moulds and dust mites and VOCs. In addition this report reviews the indoor exposures to the INDEX high priority chemicals, benzene, formaldehyde, naphthalene, carbon monoxide and nitrogen dioxide, INDEX second priority chemicals, acetaldehyde, xylenes, toluene and styrene, INDEX chemicals requiring further research (Ammonia), δ-limonene and α-pinene.
