Over the last two decades, quantitative risk assessment has received increa
sing attention in Germany. By now it is also acknowledged that probabilisti
c techniques in risk assessment seem to be superior to the conventional poi
nt estimate approach. An important prerequisite for the use of probabilisti
c techniques is seen in the provision of 'standard' probability density fun
ctions for key exposure factors. For such exposure factors like body weight
, time budget, etc., default probability density functions which are repres
entative for Germany need to be developed. Guidance on probabilistic modell
ing will be needed, too. (C) 2001 British Occupational Hygiene Society. Pub
