Database information

The purpose of the Concentration Database (ConcDb) is to gather data from published exposure concentration studies and provide a simple way to search through the results of the studies. Selection criteria for the studies included is that the study design has to be representative in the city or national level. At least the following comprehensive studies are included: EXPOLIS, SHIELDS, NHANES, GerES, TEAM, NHEXAS and MACBETH. For practical reasons results are usually presented as statistical values (mean, percentiles etc.), but in addition this database also provides the measured concentrations of EXPOLIS study as individual samples.

At the moment this database provides following information for each case:

• Agent of the study
• Target area of the study (in country and/or city level)
• Type of concentration environment

  • Describes the microenvironment or medium where concentrations have been measured (home indoor/outdoor, personal, work, drinking water, indoor dust, human, soil, beverage, food, in-vehicle, school)

• Description of the data
• Description of the study
• Reference of the study
• Some relevant additional information

The user can define the search according to the specific compound, target country and few larger studies by their name.

This database is compiled as a part of the EU projects INTARESE, HEIMTSA and EnviRisk
