Pesticides Modelling

ENVIRONMENTAL MODELLING of PESTICIDES

(02/12/2022)

This page is an entry point to information that comes from the European Environmental Modelling of Pesticides Workshops that have been organized since 2001.

The scope of the European Modelling workshops is to provide a forum to discuss scientific and regulatory issues related to pesticide fate and exposure modelling at the European level. Communication between scientists from academic and regulatory backgrounds is very important to raise awareness of new developments and to facilitate the implementation of relevant new approaches into pesticide regulation. The European Modelling Workshops provide a forum for this exchange of information. Key achievements were the vivid interactions of the participants that were taken up in the appropriate fora and led to further development of  pesticides regulatory guidance in Europe.

The meetings are jointly organised by scientists from industry and researchers active in European pesticide risk assessment and bring together members of European research institutes, industry and regulatory authorities. Key topics are identified for each workshop and scientists involved in the selected topics are invited to participate and to present details of their work.

Whilst the focus was on pesticide fate and behaviour in the first workshops, scientists from the ecotoxicological effect modelling were invited to the last workshops to join the developments in different areas of environmental risk assessment of pesticides.

This work is related to the work on FOCUS (FOrum for Co-ordination of pesticide fate models and their USe) and PERSAM (software tool for predicting environmental concentrations of plant protection products. (PPPs) in soil ), conducted by the European Commission and the European Food Safety Authority.

The outcomes (agenda, presentations, resolutions) of the first 10 workshops can be found on http://www.pfmodels.org/. Results from future workshops will be reported here. The contents for the 10th European Modelling Workshop (held in York, UK, 29-31 August 2022), the 11th European Modelling Workshop, (Montpellier, France, 25-27 September 2023), and the 12th European Modelling Workshop (held in Palermo, Italy, 6-8 October) are also presented below.
