Prof. Pacyna’s expertise is on biogeochemical cycling and fluxes of mercury, other heavy metals, persistent organic pollutants, and radionuclides in the environment. Another field of his expertise is the assessment of environmental and socio-economic impacts of energy production and other anthropogenic sources on climate change and human welfare. He has carried out more than 30 EU projects within these topics. Prof. Pacyna has also been active in the implementation of environmental strategies and policies defined within international agreements on emission and flux reductions, including cost-benefit analysis of this implementation. He provided a scientific justification for the establishment of an UN Convention on reduction of mercury contamination, signed in Minamata in 2013. Prof. Pacyna is the author of more than 450 scientific publications, including more than 120 papers in peer-reviewed journals and more than 30 books and book chapters. His works have been cited more than 7500 times, bringing his citation index H to 40. In 2012 he received Life Achievement Award for recognition of his outstanding contribution to advancing scientific knowledge of heavy metals in the environment, and their impact upon human health.In 2010 Prof. Pacyna received the Bene Merito honorable decoration by the Minister of Foreign Affair in Poland for strengthening position of Poland in the international arena and in 2011 he was presented with the “White Tiger” award, the highest award in the Polish energy sector for outstanding achievements in energy and environment research.Elisabeth G. Pacyna Elisabeth G. Pacyna is a Senior Scientist at the Norwegian Institute for Air research in Kjeller, Norway. She received M.Sc. in industrial economics and Ph.D. in environmental engineering.Scientific experience of Dr. Pacyna is in the field of energy, resources, and the environment interactions. The overall topic of her research is on the development and application of tools for the assessment of socio-economic impacts of energy production on climate change and human welfare. These tools include Life Cycle Assessment (LCA) analysis and various monetary valuation methods used to value environmental benefits from the implementation of various environmental policies. She has carriedout 16 EU projects within these topics. Dr. Pacyna has also participated in several projects for the UNEP Chemicals and Nordic Council of Ministers on socio-economic and ecological impacts of energy production and other anthropogenic sources on the contamination of the environment. She has also participated in projects on development of new measures for reduction of greenhouse gas emissions from coal-fired power plants and improvement of coal combustion efficiency in power plants.
