This document contains the report from the OECD/UNEP Workshop on the Use of Multimedia Models for Estimating Overall Persistence and Long-range Transport in the Context of PBTs/POPs Assessment, held on 29-31 October 2001 in Ottawa, Canada, together ...

This Guidance Document concerns using multimedia models, i.e. generic evaluative models that can calculate overall environmental persistence (Pov) and potential for long-range transport (LTRP) covering multiple compartments such as air, water, sediment and soil.

This Guidance Document is addressed to those who are involved in risk assessment and management of chemicals called POPs (persistent organic pollutants) or PBTs (persistent and bio-accumulating toxics). It is about using multimedia models, i.e. generic evaluative models that can calculate overall environmental persistence (Pov) and potential for long-range transport (LTRP) covering multiple compartments such as air, water, sediment and soil: what models you can use to identify and characterize POPs/PBTs, what data to use, and how to use model calculations.

This document provides guidance on how to use the OECD (Q)SAR Application Toolbox to build chemical categories according to the OECD Guidance on Grouping of Chemicals. It is part of an overall effort to provide guidance on the use of the (Q)SAR Application Toolbox.

This document presents principles and helpful guides for validating (Q)SAR technology for a variety of applications.

The method described in this guidance document assesses the effects of plant protection products (PPPs), and has been validated using the active Fenoxycarb, which is known to act as an insect growth regulator (IGR), to the honey bee brood (Apis mellifera L.).

This document presents a review of fish toxicity testing for the regulatory purpose of chemical safety. The main focus is on fish toxicity, but fish bioaccumulation is also considered where relevant.
