José-J. Ortega-Calvo is a Researcher at the Institute of Natural Resources and Agrobiology of Seville, Spanish National Research Council (IRNAS-CSIC). He has worked on bioavailability and biodegradation of organic pollutants for the last 25 years. After obtaining his PhD in 1991 at the University of Seville, he worked on different microbial ecology aspects during postdoctoral stays at the University of Amsterdam (UvA, The Netherlands) and Cornell University (USA). Dr Ortega was in 2016/2017 the European President of the Society for Environmental Toxicology and Chemistry (SETAC Europe) and, from June 2017 to June 2023, a member of the Stakeholder Bureau of the European Food Safety Authority (EFSA). He is a member of the External Science Advisory Panel (ESAP) of the Long-Range Research Initiative at the European Chemical Industry Council (CEFIC-LRI), and Associate Editor of Science of the Total Environment and Critical Reviews in Environmental Science and Technology journals. Frederic Coulon is a Professor of Environmental Chemistry and Microbiology at the Centre for Water, Environment and Development at Cranfield University, UK. He has a 24-year international research and consultancy career in water, energy and soil science, diagnostic strategy and risk analysis and management. Trained in chemistry, microbiology, and environmental engineering (University of Perpignan, France) and risk management (Cranfield, UK), he led several projects on soil and water protection and recovery, industrial and hazardous waste management, wastewater treatment and risk management. His work enabled to construct innovative decision-support tools for contaminated sites that improved the confidence in remediation (restoring to use) technology, reduce remediation costs and minimize waste disposal to landfill, with subsequent savings in CO2 emissions. His work further influences policy development and provides pragmatic, risk-based solutions to remediate contaminated sites. He has published numerous articles in leading environmental engineering and science journals, book chapters and articles for the popular press with substantive contributions to oil remediation, process emission and control at industrial sites and environmental risk management. He is the chair of the NICOLE Academic subgroup, the leading European network on sustainable land management of industrially contaminated sites, co-Editor in Chief of Environment International, Section Editor of Heliyon Environment and Associate Editors of Science of the Total Environment and Critical Reviews in Environmental Science and Technology journals.
