International co-operation among OECD member countries on (Q)SARs started in the early 1990s. The objective of the OECD (Q)SAR project is to facilitate practical application of (Q)SAR approaches in regulatory contexts by governments and industry and to improve their regulatory acceptance.
Structure-Activity Relationship (SAR) is an approach designed to find relationships between chemical structure (or structural-related properties) and biological activity (or target property) of studied compounds. As such it is the concept of linking chemical structure to a chemical property (e.g., water solubility) or biological activity including toxicity (e.g., fish acute mortality). Qualitative SARs and quantitative SARs,

This document contains an analysis of data on 205 polymers to identify correlations between polymer characteristics and the potential for health or ecotoxicological concern.
L’OCDE vient de mettre au point un instrument novateur, la Boîte à outils sur les applications des (Q)SAR, pour évaluer les propriétés dangereuses des produits chimiques en analysant leur structure moléculaire.
Revised Guidance for Grouping of Chemicals. Considers closely related chemicals as a group, or cateogory, rather than as individual chemicals. In this approach, not every chemical needs to be tested for every endpoint.
The main electronic tool for data submission, evaluation and exchange used in the OECD Cooperative Chemicals Assessment Programme is the International Uniform Chemical Information Database (IUCLID). IUCLID is a software program for the administration of data on chemical substances.
The OECD Harmonised Templates are standard data formats for reporting reults of studies with chemicals in order to determine their properties and effects on human health and the environment.
