RAIDAR (Risk Assessment, IDentification And Ranking ) modelRAIDAR is an evaluative, regional-scale, mass balance model for screening level exposure and risk assessment.
The model simulates chemical fate and transport in the environment, bioaccumulation in a range of species, food web bioaccumulation, far-field exposures to humans and representative ecological species, and effects (risk).
The general intent of the model is to screen and prioritize large numbers of chemicals based on hazard, exposure and risk assessment objectives for more comprehensive, higher-tiered assessments. The model has been used for high-throughput risk assessments for Environment Canada to address legislation outlined under the Canadian Environmental Protection Act 1999.
