Models and software to assess wildlife health.
Qonfluens is an R&D and consulting company for environmental risk assessment. We turn laboratory, in vitro and mesocosm data into predictive models that regulators, industry and research teams can use.
What we do
From test results to risk across landscapes
We work with academic and industrial R&D teams, from a single toxicity test to the exposure of a whole food web.
Regulatory statistics
Dose-response and species sensitivity distribution (SSD) analyses that follow OECD test guidelines and OECD guidance No. 54.
Survival, reproduction and growth tests; ECx and HCx estimates.
Mechanistic modelling
Toxicokinetic and toxicodynamic (TK-TD) models, such as GUTS and PBTK, that explain effects over time and extrapolate them to new exposure scenarios.
From lab and in vitro data to predictions in silico.
Spatial risk
Exposure to pollutant mixtures and their effects across landscapes and food webs, from soil contamination maps to risk indices.
SPACEMOD and the spacemodR package.
Ecotox Lab
Free web apps for ecotoxicology
Fit dose-response models, build species sensitivity distributions and explore ecotoxicological datasets in your browser. No account needed.
Standard OECD statistics
SSD fitting, survival, reproduction and growth dose-response.
Ecotoxicology datasets
BAPPET and BAPPOP, Eco-SSL endpoints, more than 200 survival time series.
Spatial and advanced models
SPACEMOD, land-use visualisation and TK-TD model previews.
Open science & projects
Research and code you can check
Our current research projects and the tools we publish. Regulatory users need to know exactly which model produced a result, so our code is on GitHub.
SPACEMOD project
Spatially explicit modelling of chemical exposure and its impacts on terrestrial food webs, to support risk assessment and the rehabilitation of polluted sites. Its Shiny app is in the Ecotox Lab.
spacemodR R package
The R package behind SPACEMOD: models the transfer and impacts of pollutant mixtures in food webs, using soil pollution maps.
MIND project
Multi-exposure risk indices for wild vertebrates, based on pesticide concentrations measured in hair and feathers.
Neural ODEs for mixtures code
Bayesian neural ODE TK-TD models that learn how compounds in a chemical mixture interact to affect survival.
About
Translational safety and ecological modelling
Qonfluens was founded in April 2022 in Occitanie, France. We study how biological systems respond to pharmaceuticals, chemicals and pathogens across space and time, and build mechanistic models that link laboratory findings to ecological dynamics.
Our work supports environmental risk assessment, ecosystem safety and the development of safer compounds.
Virgile Baudrot, founder and president.
