Calendex™ is an advanced exposure and risk analysis tool for estimating exposure of the U.S. population and more than 30 of its subgroups, to the following substances:
- Pesticides in food and the residential environment
- Food, air, and water contaminants
- Chemical ingredients in formulated products
The Calendex™ aggregate exposure model estimates human exposure to chemical residues in foods and home-based chemical treatments, such as pest control and turf treatments. The model assesses acute, short-term, intermediate, or chronic time periods for a large, representative sample of the U. S. population and for a wide range of subpopulations. The model simultaneously accounts for the temporal, spatial, and demographic variation in chemical use and chemical users.
The Calendex™ model is a calendar-based system that uses Monte Carlo sampling techniques to estimate the distributions of exposure. For each day of the year, the model combines exposure distributions with the probability that an exposure to a given compound could occur as a result of a previous or concurrent application of a product containing that compound. The model takes into account the probability that exposures to more than one product may occur on a single day, and provides a more realistic exposure assessment than would occur if exposures resulting from single uses were summed.
