ABSTRACT

The joint report of two Centers (MSC-E and CCC) includes the results of work on monitoring and modelling long-range transport of persistent organic pollutants in the EMEP region. For the sake of convenience and taking into account the interests of different groups of users - policy makers, scientists, and public - investigation results are presented in the form of the EMEP Report consisting of Part I and Part II and a number of Technical Notes.

In Part I of the report we present a summarized information on POP transport and accumulation (for PCB, B[a]P, and g-HCH) in air, sea water, soil, and vegetation of European countries in 1997 obtained by the analysis of long-range transport modelling results for the above pollutants for the period from 1970 to 1997. An attempt to compare emissions, concentrations and depositions over different European countries was made. Model calculations are compared with available measurement data. Here we present also the results of investigations of long-term accumulation tendencies within one country exemplified by Great Britain.

Part II of the report describes further development and modification of the multicompartment model and at the analysis of long-term POP accumulation and degradation tendencies in different media. Here the results of model sensitivity study with respect to a number of introduced processes and parameters are discussed.

The report is complemented by two Technical Notes [Vulykh and Putilina., 2000] and [Strukov et al.., 2000]. First work contains a detailed description of HCB physical-chemical properties, and the second one - the description of modified marine block integrated into MSC-E POP model.

The preparation of some sections was performed in collaboration with national experts as well as using result of investigations carried out under national programmes.
