Stephanie Bopp is a scientific project leader at the European Commission Joint Research Centre (JRC) in Ispra (Italy). She works in the Chemical Safety and Alternative Methods Unit, which develops, evaluates, harmonises and promotes innovative methods for the regulatory safety assessment of chemicals used in a variety of sectors, with the additional aim of protecting animals used for scientific purposes. Stephanie is leading the activities related to combined exposures to multiple chemicals and related to the Information Platform for Chemical Monitoring (IPCHEM). Furthermore, she is interested in the interface between food safety and sustainability, e.g. in relation to the sustainable use of pesticides. Before, she worked in the European Food Safety Authority (EFSA) on pesticide environmental risk assessment, at the JRC in the area of environmental toxicogenomics, and at the University of Basel on biological monitoring, ecotoxicology and passive sampling. She has degrees in Geoecology/Environmental Sciences (University of Bayreuth) and a PhD in Environmental Toxicology and Chemistry (Helmholtz Centre for Environmental Research UFZ/University of Rostock).

Tools and monitoring/surveillance data to assess the impact of multiple pesticides

Abstract of talk
Multiple pesticides are typically applied at different points in time in agricultural landscapes. Environmental risks resulting from pesticide use are assessed during the pesticide approval process. Such assessments are based on predicted environmental concentrations. A way to advance the assessment of impacts of multiple pesticide uses on the environment is to look retrospectively into exposure and effects through monitoring/surveillance. A wide range of occurrence data of chemicals for various media in Europe and beyond are made available in the Information Platform for Chemical Monitoring (IPCHEM; https://ipchem.jrc.ec.europa.eu/), run by the European Commission in collaboration with EU Agencies and many other partners, data providers and data users. IPCHEM hosts monitoring data for environmental media (water, soil, air, biota), chemical occurrences in food and feed, indoor air and humans. It currently comprises more than 450 million concentration measurements covering more than 3000 substances, including many pesticide active substances. Such data could help to refine exposure estimates and account for exposure to multiple chemical pesticides in future risk assessments. The Land Use/Cover Area frame statistical Survey Soil (LUCAS Soil; https://esdac.jrc.ec.europa.eu/projects/lucas) is an ongoing large EU monitoring campaign performed in 3-4 year intervals. Since 2018, it includes the analysis of a wide range of pesticides across a large set of soil samples collected from all over Europe. Exposure and toxicity data can then be combined to calculate risks of single or multiple pesticides to soil (micro)organisms at EU-wide level. Relationships with other stressors and impacts can also be explored, as e.g. genetic biodiversity is measured in a subset of the soil samples. Monitoring data also enable verification of exposure models for pesticides. A recent modelling exercise conducted by the JRC estimated use quantities of virtually all active substances presently authorised in the EU market. Based on the estimates and using a spatially explicit, GIS-based model, predicted environmental concentrations could be computed in EU soils and rivers. Concentrations can be combined to further compute indicators of the potential cumulative toxic effects, such as sums of toxic units. The comparison of computed and measured concentrations as available from the monitoring data increases our understanding of the fate and transport of pesticides at the continental scale.
