Plenary Overviews

Five plenary lectures will be presented, one lecture each day. Two plenary lectures are related to the Theme 1 of the Conference and one plenary lecture for each of the remaining Themes.

The titles of the plenary lectures are presented below with a short introduction of invited lecturers.

Theme 1 on How is mercury cycling changing on the global, regional and local scales in response to perturbations caused by major anthropogenic drivers of the change. ​


Plenary lecture 2 on Marine mercury cycling in a changing environment by Dr Lars-Eric Heimbürger-Boavida 

Lars-Eric is a CNRS researcher at the Mediterranean Institute of Oceanography at the Aix-Marseille-University in France. He was trained in environmental and analytical chemistry at the University of Jena and the Leibniz Institute for Baltic Research Warnemünde. After a PhD in Chemical Oceanography at the Villefranche Oceanographic Laboratory, he worked at Geosciences Environment Toulouse and the University of Bremen. Lars-Eric is interested in the application of novel techniques to outstanding questions on trace metal cycling in the ocean, with an emphasis on low-level speciation, stable isotopes and sensor approaches. Lars-Eric organized several intercalibration exercises to improve mercury species measurements in seawater. A fundamental question is how much mercury resides in the oceans, and which portion of it makes its way up the marine food chain. Trying to find answers, Lars-Eric participated in over 30 oceanographic cruises, sailing the Mediterranean, Black and Baltic Seas, the Atlantic, Southern and Arctic Oceans. During those expeditions he had the singular opportunity to visit the North Pole and the magnetic South Pole. 


Plenary lecture 3 on Terrestrial mercury cycling in a changing environment by Dr Martin Jiskra

Martin Jiskra is currently a Swiss National Science Foundation Ambizione Fellow in the Department of Environmental Science at the University of Basel, Switzerland. He received his PhD from ETH Zurich, Switzerland in 2014 and was an EU Marie-Sklodowska Curie Fellow at the French National Center for Scientific Research CNRS in Toulouse from 2015 to 2017. His research uses mercury stable isotopes to better understand the cycling of mercury in terrestrial ecosystems. The main research interests are the terrestrial-atmosphere exchange of mercury and transformation and transport processes in soils. Martin Jiskra has previously been working in boreal and Arctic ecosystems. His current work focuses on the uptake of atmospheric elemental mercury by vegetation across Europe. The research questions are addressed by combining the novel mercury stable isotope fingerprinting tool with remote sensing and modeling techniques. He is also interested in developing new analytical techniques and new applications using mercury stable isotopes.  

Theme 2 on What is the relative risk of mercury exposure to human health and wildlife in the context of human welfare?


Plenary lecture 4 on The microbiome: modulating methylation in the environment and biota by Dr. Ellen Silbergeld



Trained at Hopkins in geography and environmental engineering (PhD '72) and postdoctoral fellow in Environmental Health Sciences ('72-75). NIH staff fellowship followed by senior scientist position at Environmental Defense and professorship at University of Maryland Medical School. Served as scientific advisor to NTP-NIH, CDC, EPA, DOE, OSHA, states of Maryland and New York, World Bank, ILO, UNEP, WHO, and PAHO.

My research and professional activities bridge science and public policy, with a focus on the incorporation of research in both toxicology and epidemiology into environmental and occupational health policy. Areas of current focus include: cardiovascular risks of arsenic, lead, and cadmium; immunotoxicity of mercury compounds; health and environmental impacts of industrial food animal production. These projects include epidemiological studies and mechanistic research on gene:environment interactions and the emergence and dissemination of antibiotic resistant pathogens in populations and in the environment. Some of this research is conducted internationally (mercury studies in the Amazon; lead/cadmium/arsenic studies in Mexico; mining and development in Mongolia; zoonotic diseases in Thailand and the Netherlands). 

In 2016 I was appointed as special consultant to the WHO Food Safety Programme.

Theme 3 on How can technological development contribute to the reduction of mercury exposure and improvement of environmental responsibility. How will industry achieve more control of Hg emissions, handle waste products, and clean up contaminated site?


Plenary lecture 5 on Mercury reduction from power and industry - how much is possible? by Dr. Lesley Sloss

Dr Lesley Sloss is currently Principal Environmental Consultant with the Clean Coal Centre of the International Energy Agency where she has worked since 1990. In this time, Lesley has produced over 40 reports relating to the environmental consequences of coal combustion such as emissions, the associated policies, and, ultimately, the control technologies required to reduce the environmental impact of coal use. Lesley is lead on the United Nations Environment Coal Partnership acting as advisor to the UN Governing Council on the internationally legally binding instrument on mercury emissions (the “Minamata Convention”). Lesley has overseen mercury measurement and control projects in China, India, Russia, South Africa, Thailand, Vietnam and Indonesia.

Theme 4 on  How can scientific knowledge contribute to the implementation and effectiveness evaluation of the Minamata Conventions and other regulatory agreements? Importance of integration and implementation of emerging and future mercury research into the policy making.

Plenary lecture 1 on How the implementation of the Minamata Convention requires valuable inputs from the scientific community by Ms. Rossana Silva Repetto

Ms. Rossana Silva Repetto has over 25 years of professional international experience with the United Nations.
Before joining the Secretariat of the Minamata Convention as her Executive Secretary, Rossana was performing the functions of Senior Legal Adviser and Head of the Legal Unit in the Corporate Services Division of the United Nations Environment Programme. Prior to this post, she worked as the Legal Officer of the Ecosystems Division, where she was also the UNEP Focal Point for Small Island Developing States and a member of the Interim Secretariat of IPBES. She had previously been the Legal Officer for the Regional Seas Conventions and Action Plans, and the Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities, at the Office UNEP then had in The Hague. Prior, at the UNEP Office for Latin America and the Caribbean, Rossana was the Coordinator of the Environmental Law Programme, where she organised the first ever Environmental Law Symposium for judges in the region and was the regional focal point for the preparatory process for Rio + 10.
Before joining UN Environment, Rossana worked in the Office of the Legal Counsel at the UN Food and Agriculture Organisation (FAO), where she provided advice to the Committee on Genetic Resources. As staff of the Development Law Service, she also advised governments and supported them in the drafting of legislation on the conservation and use of natural resources in the specific field of “Plant Protection”, which covers chemicals and pesticides, phytosanitary protection, seeds and genetic resources. Within the chemicals and pesticides area, she worked jointly with UNEP in the preparatory process for the intergovernmental negotiations that culminated in the adoption of the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade. She was the FAO focal point for the World Trade Organisation Agreement on Trade-Related Aspects of Intellectual Property Rights, and she drafted national legislation on plant variety intellectual property protection and seeds legislation.
She also worked as a professor of International Cooperation at the University of Lima, Peru, as adviser for international affairs to the Peruvian Ministry of Agriculture, as a consultant with EnAct Environmental Law Consultants and as a contributor to the Latin American Social Studies Association at the University of Rome II.
Rossana holds a Master's degree in Law from the Katholieke Universitet Leuven, Belgium, and a Master´s degree in European Studies, International Law and the Law of International Organisations from the Post Graduate Institute of European Studies "Alcide de Gasperi" in Rome, Italy. She holds a degree in Law and Political Science from the University of Lima, Peru
