The application of structure-activity relationships in human hazard assessment: a first approach

De toepassing van structuur-activiteitsrelaties in humane effect beoordeling: een eerste aanzet

Synopsis

In this report an overview is given of structure-activity relationships (SARs) described in literature that can be helpful for the daily human hazard evaluation of chemicals. SARs describe the relation between molecular structure and biological- or physical-chemical activity of the chemical. Chemicals that share structural features are presented that can have an effect on the toxicological endpoints: irritation, sensitisation, neurotoxicity (acetylcholinesterase-inhibition), genotoxicity and reproductive and developmental. These SARs were discussed in a Workshop. The results of this Workshop, which was attended by RIVM and TNO risk assessors and experts, are presented also. One of the results is a list of structural features with possible effects on the above mentioned toxicological endpoints. It is proposed to test these SARs in the next two years on chemicals for which experimental data are available. This report may help to increase the quality of the hazard assessment.
