MCRA stands for Monte Carlo Risk Assessment.
MCRA is a web-based system for probabilistic exposure and risk assessment of chemicals in the diet.
The MCRA system brings together statistical models, shared data and data uploaded by the user.
MCRA 8.3-TEST also provides Cumulative Exposure Assessment for chemicals grouped in a Cumulative Assessment Group for which a single health effect is considered relevant.
Optionally exposure from other routes can be added in an Aggregate Exposure Assessment.
MCRA 8.3-TEST was developed in EU project ACROPOLIS and is further developed in actions for EFSA and in EU project EuroMix
