This study revealed that fipronil and its derivatives had a toxic effect on the survival of juvenile springtails but at high concentrations which are not realistic. F. candida reproduction seemed to be slightly inhibited by fipronil but springtails seemed to be able to avoid highly contaminated soil zones. Therefore, the global Risk Quotient might be acceptable for most of the time. Soils that were weakly contaminated by fipronil could be partly detoxified by F. candida organisms (essentially adults) to produce metabolites at a non-negligible rate. In order to assess the realistic toxicity of fipronil on springtails and to evaluate their remediation efficiency, mesocosm experiments are necessary mainly to demonstrate the avoidance of highly contaminated zones. Furthermore, field studies would be beneficial to compare former and actual agronomic soils and natural soils in terms of biodiversity and survival of Collembola populations.
