This report has been prepared for the Helsinki Commission (HELCOM), Baltic Marine Environment Protection Commission, based on the model estimates and monitoring results which have been presented to the Third Joint session of the Working Group on Effects and the Steering Body of EMEP (Co-operative Programme for Monitoring and Evaluation of Long-Range Transmission of Air Pollutants in Europe). This joint summary report for HELCOM includes the measurements and results of modelling in the Baltic Sea region for oxidised nitrogen, reduced nitrogen, lead, cadmium, mercury and POPs for the year 2015. It has been produced in the frame of close collaboration between the three modelling and monitoring EMEP centres MSC-W, MSC-E and CCC, and is available now on the EMEP web site and later on the HELCOM web site. The report, as a draft, was presented to and discussed at the PRESSURE Meeting in Vilnius, Lithuania, together with corresponding drafts of the Baltic Sea Environment Fact Sheets (BSEFS). Participants of this meeting were asked for comments and corrections which were taken into account in the final version of the report, which can be found below, and also in the final versions of the BSEFSs.

Acknowledgements. The authors are indebted to the scientific teams at MSC-E, MSC-W and CCC for providing the results included in this report. We are grateful to Dr. Ilia Iliyn and Prof. Victor Shatalov for their contribution to this work, valuable remarks and comments.

Separate Chapters of the report, including the Baltic Sea Environment Fact Sheets can be found below.
