Alice & Charles are presenting at Akademie Fresenius

We’re proud to announce that 2 of our Senior Ecotoxicologists Dr Alice Tagliati and Dr Charles Hazlerigg will be speaking at the upcoming Akademie Fresenius Endocrine Disruptors (ED) and Aquatic and Terrestrial Ecotoxicity conferences in Cologne, presenting insights on using population modelling in the hazard and risk assessment of plant protection products (PPPs).

Thursday 30th November
Endocrine Disruptors
Dr Alice Tagliati
Population relevance of endocrine disruptors

Population modelling, field studies and monitoring approaches have all been proposed for assessing the effects of Endocrine Disrupting Chemicals (EDCs) at the population level for non-target vertebrates, however, the relevant European Guidance Document by ECHA & EFSA (2018) does not specify how these approaches should be used in the regulatory EDC hazard assessment. Consequently, the regulatory procedure for the authorisation of PPPs and BPs under their European regulations is often unclear. In her talk “Population relevance of endocrine disruptors” on Day 1 at 17:05 CET of the 14th International Akademie Fresenius Conference: Endocrine Disruptors, Alice will discuss how models may be parameterised or field studies designed so that they are consistent with the regulation (i.e., specifically, performing a hazard assessment). This would reduce the need to make the (often incorrect) simplifying assumption that an effect at the individual-level will inevitably translate to an effect at the population level. Do not hesitate to get in touch with Alice during the event or via email:

Population Modelling: Risk and hazard approaches

In 2014, EFSA published a scientific opinion on the use of effects models in the assessment of chemical environmental safety (EFSA 2014). One idea being that population models can link the effects observed in standard toxicity studies on individuals with the desired protection goal at the population level. Since 2014, there are now examples of the use of these types of models in the environmental risk assessment for Annex I Renewal for a number of active substances. More recently, we have been involved in developing the use of these models in the hazard-based regulation of endocrine disrupting chemicals – an approach that needed quite different solutions regarding model choice and parametrisation Hazlerigg et al. 2023. Please join us to discuss this current issue in chemical safety over a coffee or dinner at the upcoming Akademie Fresenius Ecotox meeting where Charles will be presenting 23rd International Akademie Fresenius ECOTOX Conference.

The event will also be live streamed, so whether you’re in Cologne or attending virtually we hope you enjoy these insightful sessions.
