Modelling of the environmental distribution and fate of persistent organic pollutants on a national, European and global scale - AQ01029

Description

The fate and behaviour of persistent organic pollutants (POPs) in the environment has attracted considerable scientific and political interest, arising from concern over human exposure to these chemicals and their discovery in pristine environments far from source regions. The ability of certain POPs to undergo long range atmospheric transport (LRAT) has resulted in the negotiation of international protocols (e.g. UN/ECE, UNEP) for their reduction or elimination, to reduce the risks to regional and global environments. The development of such protocols recognises the regional and global nature of many POP compounds. As part of this contract for Defra, Lancaster University has developed a number of modelling tools that can be used to investigate the potential environmental impact of existing and candidate POPs. The most recent model development is a regionally segmented multimedia fate model covering the European continent. This model has been designed to examine the environmental fate and behaviour of a wide range of chemicals and to investigate a number of emission scenarios and source reduction strategies. It can also be used as a predictive tool to identify potentially important sinks and for estimating the potential for long-range atmospheric transport. Models such as this can be helpful in understanding the movement from source to sinks. The model development work has been complimented by a number of measurement exercises aimed at improving the description of key processes and providing datasets for calibration and validation. Although validation of models such as these is challenging, an international group of experts has been formed which is coordinated by MSC-E in Moscow. Lancaster University is an active member of this group which is currently undertaking a programme of work which intends to compare a number of POP fate models and to eventually provide meaningful validation with measurement data.
