Mr. Mark Bonnell

Senior Science Advisor - Integration and development of sciences related to the ecological risk assessment of chemicals

Fontaine Building (Gatineau, QC)

CURRENT S&T / RESEARCH - Working to ensure that chemicals assessed under the Chemicals Management Plan (CMP) best reflect the global science of ecological risk assessment

  • Provide expert scientific opinion and direction related to the risk assessment of new and existing chemcials assessed under the Chemicals Management Plan
  • Coordination and integration of global bioaccumulation assessment science for new and existing substances assessed by Environment Canada
  • Provide expert advice on the application and interpretation of quantitative structure-activity relationship (QSAR) models and mass balance environmental fate models for the PBT/POPs assessment of substances under Canadian Environmental Protection Act
  • Develop and enhance the expertise of regulatory scientists within the Science and Risk Assessment Directorate (SRAD) through technical training
  • Act as a conduit between global expert groups (e.g., OECD, HESI, SETAC, ECETOC) and regulatory scientists within SRAD


Risk assessment of over 1000 new and existing substances

QSAR PBT/POPs, long-range transport modelling and environmental fate and bioaccumulation kinetic mass balance modelling

EC representative at international expert forums on hazard (PBT) and risk assessment science (OECD, SETAC Global Advisory Groups, HESI)
