Quantifying and reducing uncertainty in model calculations of global pollution fate

Updated 2000-06-30

The main objective of the project is to describe quantitatively with model calculations the global distribution behaviour of persistent organic contaminants, and to establish credibility in the results of these simulations.

This is not a National Implementation Plan (NIP) project
