Exposure limit setting for the work environment

Denna sida på svenska

Today occupational exposure limits (OELs) are derived on a national level in many countries and also on the EU-level. There are also exposure limits under other legislations that may affect workers’ protection. An example is the Derived No Effect Levels (DNELs) which manufacturers and importers of chemicals substances shall derive under the EU chemicals legislation REACH. In our research we scrutinize OELs and other exposure limits from a toxicological perspective and investigate the methodology for deriving these, such as the use of assessment factors to cover uncertainties in the available data. The major objective is to contribute to transparency and consistency in the derivation of exposure limits.
