Air Quality Benefits Assessment Tool (AQBAT)
The Air Quality Benefits Assessment Tool (AQBAT) is a computer application developed by Health Canada which is designed to estimate the human health impacts of changes in Canada’s ambient air quality. It is used to estimate the benefits (positive impacts) or damages (negative impacts) of proposed regulatory initiatives related to outdoor air quality as mandated by the Treasury Board Cabinet Directive on Regulatory Management.
- allows the user to define a wide range of scenarios combining pollutants, health endpoints, geographic areas and scenario years
- consists of a Microsoft Excel file with numerous controls to enable the user to define, run, examine and save the inputs and outputs for specific scenarios
- contains sheets of historical and projected population data, pollutant concentration data, annual baseline health endpoint occurrence rates, and Health Canada endorsed concentration-response functions and health endpoint valuations
- utilizes the @Risk add-in software to perform Monte Carlo simulations, which allow the user to examine the effects of uncertainties on estimated health impacts
