Monte Carlo Risk Assessment

Probabilistic modelling of chemical intake from food

In a Monte Carlo dietary risk assessment the exposure to chemicals from the diet is quantified as a distribution by combining information on food consumption with information on concentrations of chemicals in food.
 
MCRA is intended for users who want to analyze their own or shared data and chemical concentration data.

MCRA is developed in collaboration between RIVM and Biometris in the context of the Dutch Programme for the Quality of Agricultural Products (KAP). 

Main features of MCRA are: 

• Data selection from e-platform of MS Access databases, or from a simple MS Excel table (7.0)
• Conversion of food-as-eaten to food-as-measured, model for brandloyalty (7.0)
• Quantification of short-term exposure (personday intake) for acute risk assessment
• Quantification of long-term exposure (usual intake) for chronic risk assessment
• Modelling of concentrations, including models for nondetects and unit variability
• Modelling of food processing effects
• Uncertainty analysis
• For acute risks comparison with point estimates (IESTI)
  

Current version are MCRA 6.2 and 7.0 beta (selected users).
