Proposal for a 'standard' field study for the evaluation of the effects of parasiticides on dung and soil organisms

Numerous published studies and most authorisation procedures of parasiticidal products have shown that simple laboratory studies typically demonstrate a risk for dung fauna and/or soil dwelling invertebrates. Hence, there is a need for a more advanced standard test in order to evaluate risk under more realistic field conditions. In order to develop and validate such a field test, comparable investigations were conducted under varying conditions at Lethbridge (Canada), Montpellier (France), Zurich (Switzerland), and Wageningen (the Netherlands). Results of this project were published in 2016 in a series of articles in Environmental Toxicology and Chemistry vol. 35(8):1914-1977. This poster presents some of the lessons learned and recommendations from a methodological point of view.
