This report has been prepared for the Helsinki Commission (HELCOM), Baltic Marine Environment Protection Commission, based on the model estimates and monitoring results which were presented to the Fourth 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, cadmium, mercury, benzo(a)pyrene and PCB-153 for the year 2016. It has been produced in the frame of a collaborative effort by the three modelling and monitoring EMEP centres MSC-W, MSC-E and CCC, and will be available on the EMEP web site and later also on the HELCOM web site. The report, as a draft, was presented and discussed at the PRESSURE Meeting in Riga, Latvia, in October 2018 along with corresponding drafts of the Baltic Sea Environment Fact Sheets (BSEFS). Participants of the PRESSURE Meeting were asked for comments and corrections which were taken into account in final version of the report and fact sheets, which can be found below.

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