This report is prepared for the Baltic Marine Environment Protection Commission under (HELCOM), based on the model estimates and monitoring results, which were presented to the Fifth Joint session of the Working Group on Effects and the Steering Body of (EMEP) in September 2019. The report includes the measurements and results of modelling in the Baltic Sea region for oxidised nitrogen, reduced nitrogen, cadmium, lead, mercury, and PCDD/Fs for the year 2017. It has been produced in a collaborative effort by the three modelling and monitoring EMEP centres MSC-W, MSC-E and CCC, and will be publicly available on the EMEP website and later also on the HELCOM website. The report, as a draft, was presented and discussed at the PRESSURE Meeting in Brussels in October 2019. Participants of the PRESSURE Meeting were asked for comments and corrections, and these were taken into account in the final version of the report and fact sheets published here.

Acknowledgements The authors acknowledge contributions from their colleagues at the EMEP Centres MSC-E, MSC-W, CCC, and CEIP for providing the data this report is based on. In particular Anne-Gunn Hjellbrekke, Dr. Ilia Iliyn and Prof. Victor Shatalov have contributed to this work, also with valuable remarks and comments.
