Applied toxicological modeling, analysis, and decision support.

EcoTox LLC provides applied toxicological support for environmental decision-making through the work of Kevin Brix, Principal Scientist. Services emphasize defensible analysis, transparent modeling, and practical interpretation of complex environmental data. Work includes particular experience with metals and metalloids in aquatic systems, while also addressing broader environmental toxicology questions.

Toxicological and Environmental Assessment

Support for evaluating chemical stressors, biological responses, and ecological risk in aquatic systems, including interpretation of laboratory and field toxicity data for metals, metalloids, and other contaminants.

Areas include:

  • Aquatic toxicology
  • Metals and metalloids in aquatic systems
  • Ecological risk assessment
  • Effects-based interpretation of laboratory and field data
  • Water quality criteria and regulatory support
  • Weight-of-evidence evaluations
  • Technical review of environmental studies and models

Bioavailability, Bioaccumulation, Mechanistic, and TKTD Modeling

Development and application of models describing how environmental chemistry, exposure, uptake, elimination, and biological response influence toxicity and environmental risk.

Areas include:

  • Empirical bioaccumulation modeling
  • Metal bioavailability models
  • Tissue-residue interpretation
  • Adverse outcome pathways
  • Food-web and trophic-transfer modeling
  • Toxicokinetic and toxicodynamic model development

Data Analysis and Decision Support

Quantitative analysis of environmental datasets to support interpretation, communication, and defensible decision-making.

Example areas include:

  • Concentration-response modeling
  • Hierarchical and Bayesian analysis
  • Time-series exposure analysis
  • Site-specific model calibration
  • Scenario analysis
  • Data visualization and technical reporting
  • Reproducible analysis workflows
