Role in the Project

Jason will provide input and lead the environmental risk elements of WP 5 (WP5; Risk management and policyLeads Wellington (UK) and Taneja (I)) ensuring the quality and assurance of the risk assessments produced. He will develop recommendations for environmental monitoring guidelines to inform a risk assessment protocol with the Indian project partners. This will be achieved through the development of an environmental exposure risk model. The work will be integrated across all project disciplines in order to address the key aim above. The project will enable understanding of the many impacts of antimicrobial manufacturing waste pollution and underpin options for the future management of such antimicrobial wastes and their disposal. 


  • Risk assessment protocols will provide guidance to relevant authorities.
  • Data gathered throughout by project partners will be used to complete a risk assessment to determine the environmental and human health risks.
  • The risk assessment will contain the following information:
    • Overview of the hazard characterisation
    • Estimate of the level of risk 
    • Risk mitigation and management recommendations
  • A risk assessment will be used to develop recommendations for environmental monitoring guidelines
  • To develop better understanding of the most effective mitigation strategies for use by policymakers and regulators.
