The ESA is a three step process which helps us to identify candidates for evaluation:
Step 1 – High throughput selection of candidates by using hazard and exposure information to develop a risk profile.
Step 2 – Application of weighting modifiers to determine relative risk:
- reports of adverse events
- international regulatory action
- effects occur at low exposures
- vulnerable sub-populations identified
- potential for bioaccumulation
- extreme persistence
- known introduction in Australia including detection of the chemical in Australian monitoring data.
- volume introduced
- stakeholder need for information.
Step 3 – Determining overall priority for evaluation based on risks and available resources, data, and information:
- our capacity and resources
- maximising work efficiencies
- quality and quantity of available data
- relative risk weightings
- initial risk profile and existing risk management controls
- capacity of risk managers and stakeholders to respond to evaluation outcomes.
