Biological agent reference value

from Wikipedia, the free encyclopedia

The biological agent reference value ( BAR value) is used to describe the background exposure in the human body to an agent. The working-age population who has no professional contact with the substance used is used to record the background exposure. By orienting itself towards the 95th percentile of a defined population group, the BAR does not take any health effects into account .

Since 2008, the permanent Senate Commission for the testing of harmful substances of the German Research Foundation (DFG) has published BAR values. So far (as of July 2015) there are BAR values ​​for 24 substances. They are documented in the occupational health and toxicological explanations for BAT values , EKA, BLW and BAR .

According to the occupational health rule (AMR) 6.2 " Biomonitoring ", the biological reference values ​​of the DFG may be used to assess biomonitoring findings that were collected from an employee as part of preventive occupational health care .
