Desk-Based Ecotoxicology Assessment


We evaluate potential effects on non-target organisms using existing experimental data and validated alternative methodologies.

Capabilities include:

  • Systematic data gathering and reliability assessment

    • Endpoint relevance and comparability analysis

    • Use of read across, analogue approaches, and QSARs

    • Derivation and justification of assessment endpoints

      • Weight of evidence hazard evaluation

      Data gaps and uncertainties are clearly identified and scientifically addressed.



            Environmental Fate Assessment


            Environmental fate assessment forms a core component of our desk-based services and underpins exposure and risk characterisation.

            We assess:

            • Degradation and abiotic/biotic transformation processes
            • Persistence and mobility in environmental compartments
            • Partitioning behaviour and environmental distribution
            • Bioaccumulation and biomagnification potential
            • Interpretation of laboratory, field, and monitoring data


            Where appropriate, modelling outputs are integrated and critically evaluated.

              • Environmental Exposure & Risk Assessment

              We integrate hazard and fate information into structured environmental risk assessments tailored to the substance use profile and regulatory framework.

              ERA services include:

              • Problem formulation and conceptual exposure modelling
              • Predicted Environmental Concentration (PEC) derivation
              • Effects threshold selection and PNEC derivation
              • Risk characterisation and refinement
              • Evaluation of uncertainty and conservatism

              All assessments are fully documented to support regulatory review.
