Carole BEDOSAfter a PhD in atmospheric physico-chemistry focusing on aerosol modelling, Carole Bedos has been working as a Researcher for INRAE since 1999. Her main research interests are pesticide emission to the atmosphere, atmospheric dispersion and deposition, and recently population exposure to pesticides via the atmosphere. Her area of expertise therefore covers the fate of pesticides in the atmosphere as well as the associated experimental methodologies from the lab to field conditions and modelling at the local and regional scale. She also contributes to national working groups for ministries and French Agency for Food, Environmental and Occupational Health & Safety on the mitigation of pesticide emissions to the atmosphere, recommendations for national monitoring of air contamination by pesticides or recommendations for the assessment of resident exposure to pesticides. Sophie GENERMONTSophie Génermont has been working as a Researcher at INRAE from 1992. She is an agronomist, and from her PhD. thesis in atmospheric physico-chemistry, she has been studying ammonia volatilization from cropped fields. She is developing transfer tools and structures for both measurement and modelling at local and regional scales. She is involved as task carrier or coordinator in projects on fertilization and/or air pollution. Her research theme is part of the agronomic and environmental assessment of the agricultural recycling of organic waste products generated by anthropogenic activities and the nitrogen fertilization of crops most specifically in terms of air quality. She contributes to national and international expert groups relative to these subjects. She also leads a nationwide technology network on the issues of recycling, fertilization and environmental impacts involving some 40 research, R&D, development and educational organizations.Jean-François CASTELLAfter a master degree in ecology and plant ecophysiology, Jean-François Castell has been teaching crop physiology and environmental physics at AgroParisTech from 1988. His research at INRA initially focused on the water functioning of plants and the water balance of vegetation and since the 1990s has been switched to the study of the impacts of atmospheric pollutants on the ecophysiology of plants and on crop yields and ecosystem functioning. More specifically, he is working to quantify the impact of ozone on wheat yields in France and Europe.Pierre CELLIERAfter a master degree in agronomy in 1979, Pierre Cellier has been working on physics and chemistry of the environment in the context of agricultural research at INRAE. This applied first to spring frost prediction (PhD in 1982), evapotranspiration measurement and soil temperature prediction. From the 1990’s, he moved to analysing and modelling agriculture-air pollution-greenhouse gases relationships with a focus on nitrogen and related compounds (NH3, N2O, NO, O3) and pesticide volatilization. He has also been working on dispersion and deposition of NH3, pesticides and particles in the vicinity of agricultural sources and on landscape scale modelling of nitrogen transfer and transformations.Pierre Cellier has been involved in building research programs with French applied research institutes, in European networks and research projects, as well as expert groups. He is often participating in French expert groups or scientific committees dealing with nitrogen and air pollution.
