Aims
Quantifying the risk of occupational factors such as chemical substances is essential to protect human health at workplaces. Hence, the use of the best methodology for risk assessment and derivation of dose-response relationships (DRR) is a scientific challenge. There is much experience in risk assessment among OSH-professionals. Joint research by PEROSH institutes offers a great chance to share know-how, resources and money.

The DRR project aims to collaborate on the derivation of dose-response relationships for relevant chemical substances in OSH. Knowledge transfer on risk assessment methodologies will improve the derivation of DRR’s and will be applied to a series of new chemical substances chosen by the project members.

All PEROSH institutions can make suggestions for specific, relevant chemical substances for DRR derivation, the collaboration for each substance is optional.

The DRR working group develops a consensus method paper on the derivation of scientific based dose-response relationships (DRR) for chemicals. The members of the working group want to bring together expert knowledge and want to offer recommendations for a systematic approach for this derivation.
The systematic identification and evaluation of toxicological and epidemiological studies are essential steps for this approach. So it can be very helpful to have a list of important sources and databases for identifying studies. Additionally, checking sources for finding existing risk assessment documents or scientific criteria documents for specific chemicals can provide useful information and safe time.

The following lists are draft collections on relevant sources for searching studies and criteria documents on DRR’s. A further list is about literature on DRR methodology.
