Student groups with an even number of female and male students at the age of 20 to 29.

The students come usually from different regions in Germany to the universities and are selected for non-specific exposure. With individuals and groups moving home frequently in a mobile society, it is assumed that almost the entire country is represented.

At each of the four sampling places about 100 students donate blood and a 24h-urine sample every year. Until 2004 they provided additionally saliva, scalp hair, and pubic hair. The anamnesis data and habits are collected in a standardised questionnaire.

Target organs/Matrices

  • Ideal matrix for most chemicals because it is in contact with the whole organism and in equilibrium with the organs and tissues in that chemicals are being accumulated
  • Ideal matrix for most chemicals because it is in contact with the whole organism and in equilibrium with the organs and tissues in those chemicals are being accumulated.
  • Particularly suitable matrix for human biomonitoring because chemicals and/or their metabolites excreted with urine have been in direct contact with the organism. Therefore, measurements in urine can give valid information regarding the internal human body burden.
  • Via element analysis in saliva release of alloy components of dental (prothesis) materials can be assessed.
  • Ideal matrix for the detection of internal exposure to methylmercury.
  • Ideal matrix for the detection of internal exposure to methylmercury.
