This report was prepared for the Helsinki Commission (HELCOM), Baltic Marine Environment Protection Commission, based on model estimates and monitoring results presented to the twenty-fourth session of the Steering Body of EMEP (Co-operative Programme for Monitoring and Evaluation of Long-Range Transmission of Air Pollutants in Europe). This present, fourth joint summary report for HELCOM includes the measurements and results of modelling in the Baltic Sea region for oxidized nitrogen, reduced nitrogen, lead, cadmium, mercury and lindane for one particular year - 1998. It was developed in a frame of close collaboration between three modelling and monitoring EMEP centres: MSC-W, MSC-E and CCC, and for the first time will be available only on internet, at the beginning on the EMEP WEB pages and finally on the HELCOM WEB pages. The report, as a draft, was presented at the second MONAS Meeting in Helsinki (22-23/02/2001) and participants were asked for comments and corrections which are included in the final version. Further comments, corrections and suggestions should be sent to Jerzy Bartnicki or co-authors, preferably by e-mail.

Acknowledgements. The authors are indebted to the scientific teams at MSC-E, MSC-W and CCC for providing the results included in this report and especially to Egil StÝren and Amund Bjerve from MSC-W for their help in designing the internet version. We are most grateful to Sergey Dutchak, Alexander Ryaboshapko, Ilia Iliyn, Victor Shatalov, Larissa Zayavlina, Irina Strijkina, Olga Rozovskaya and Svetlana Yevdokimova from MSC-E, and to Anne-Gunn Hjellbrekke and Rita Larsen from NILU for their help in preparation of this report.
