The risk assessment for workers handling hazardous substances is based on the evaluation of substance-intrinsic properties and the occupational exposure assessment.
Currently the measuring methods for occupational dermal exposure are not harmonized. For existing measurement methods scientific studies are missing concerning the evaluation of significance and applicability. There is a lack of systematic investigations carried out by means of different measurement methods for the determination of dermal exposure. Especially information concerning the comparability of measurement results from different methods is missing. Additional there is a need for a better investigation how far a measurement method takes into account the physical and chemical properties of the individual hazardous substance.
There is an open question, which measurement method would be the most suitable for which task. In addition, the comparability of results from different measurement methods will be investigated.
For this purpose the dermal exposure of probands performing selected tasks under defined and standardised conditions is to be determined in test chambers. The dermal exposure will be quantified for different exposure situations (task + ambient conditions + substance) by various measurement methods respectively.
The aim of the research project is the generation of scientific knowledge to improve and standardise measurement methods for dermal exposures to chemicals at the workplace.
