Guidance Document on the Use of Multimedia Models for Estimating Overall Environmental Persistance and Long‑Range Transport

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.
