4.1 CCEF Life Stages

It is critical that the CCEF be able to accommodate the various life stages of a human to develop the aggregate and cumulative health effects. To effectively model the aggregate and cumulative health effects of high volume compounds, a number of different life stages must be taken into account for each scenario. The age definitions of each life stage and terminology may vary but the presented information is a good guideline to follow.

This section introduces these life stages. Move your mouse over the timeline for a description of the life stages. For information on the specific life stages involved in each Exposure Scenario, click on the individual scenario of interest.
