LifeLine Customized Dietary Assessment Software™ v1.0.4 - Features

Exposure and Risk Assessment for Unique Diets

CDAS™ calculates exposure and risk from chemicals in the diet, considering two different dietary patterns. The assessor may define a unique/atypical diet through the DRG ™ and then calculate the exposure and risk. This same process can be done for a diet defined by the CSFII.

Menu Blending

The dietary proportions that have been contributed from each diet can range from 100 % for either of the diets of there can be a mix of each. In the diagram below the contribution from the CSFII has been set at 70% and the unique diet has contributed 30% of the intake.

The dietary assessment also considers seasonal variability in dietary habits, food sources with their inherent contaminants, and temporary changes in menu options (population mobility) for the population of concern. The assessor may define a season in which the dietary profile is different, food sources are different, or proportions between the dietary profiles are different.

CDAS™ Model Details

LifeLine Customized Dietary Assessment Software™ is comprised of four modules. A tutorial guides the user through each of these modules.

  • STEP 1 Food Residue Entry Module:
    • attach chemical residue values to the foods consumed by the population of concern;
    • NOTE: The list of foods to which the assessor attaches residue information may come from the USDA’s Continuing Survey of Food Intake by Individuals (CSFII) , or it may be custom designed by the user in a separate software called the LifeLine Dietary Record Generator™ (DRG™).
  • STEP 2 Active Ingredient/Chemical Description Module:
    • create an active ingredient/chemical profile to describe the chemical of concern;
  • STEP 3 Exposure Analysis Module:
    • use files created in previous modules to run exposure and risk Assessment
  • STEP 4 Report Generator Module:
    • creates user customized tables and graphs to summarize Assessment results
  • STEP 5 Summary Report:
    • creates an Adobe Acrobat file with tables and graphs in a format requested by the US Environmental Protection Agency’s Office of Pesticide Programs.
