LifeLine™ - Version 5 Features


LifeLine™ Version 5 provides a modification to LifeLine™ Version 4.3. The analyst may now choose to generate a summary report as required for submissions to US Environmental Protection Agency's Office of Pesticide Programs at the point of setting the parameters of the analysis. In Version 4.3, the option for the summary report could be elected only after the analysis was completed (still available). Now the analyst has the option to generate two unique reports. In LifeLine™ Version 5, the first summary report can be designed when the analyst specifies the parameters of the analysis, and the second can be designed after the analysis is complete and the results considered. There have been no other changes incorporated in this version.

The capacity to prepare a summary report of key regulatory findings in a format as used by the Office of Pesticides in EPA with the added features of being able to drill down to examine:

  • The history of each individual's exposures to a pesticide from all sources
  • The patterns of exposure for populations at different ages
  • The distribution of exposure across a population at any age and season
  • The corresponding risks for acute and chronic non-cancer toxic effects associated with those exposures, as well as lifetime cancer risks.

Incorporation of the new definitions of RAC and FCID

  • The listing of Raw Agricultural Commodities (crops) has been redefined by EPA and that latest listing of crops, crop groups and food forms is included in LifeLine™ Version 5.
  • The foods in the Food Residue Translator and their linkage to the crops are redefined according to those in the Food Commodity Intake Database (FCID)1. The FCID was developed as a cooperative effort by the United States Department of Agriculture (USDA) and OPP for use by EPA and other organizations when conducting the exposure components of dietary risk assessments. The FCID includes data from two surveys conducted by USDA: Continuing Survey of Food Intakes by Individuals, and a Supplemental Children's Survey. These surveys provide useful information on 5,831 different foods and beverages people of different ages reported eating in 1994-96 and 1998. (FCID) is available on CD-ROM from the National Technical Information Service (NTIS). The product order number is PB2000-500101.
    1 Please note that because of these many structural changes to the crop listings, food listings and related pieces, previous LifeLine™ residue files and older DEEM™ files will not import into this version. Also, the USDA CSFII 1989-91 food survey has been deleted. If you wish to use these older files or databases, we recommend you maintain a copy of LifeLine™ Version 2.0 for that purpose.

The ability to input water residues (for all but tap water) in the Food Residue Translator


The ability to enter data on a food basis as well as a RAC basis

Increased speed of operation (up to 50% faster than Version 2.0)

Ability to simulate lifetime exposures for up to 20,000 individuals and to simulate exposures for up to 100,000 individuals for younger age groups

Improved documentation of the key inputs and interim values for the random day estimates of dose

Increased transparency of input files

Improved ability to directly import data files formatted for use in other dietary software programs (e.g. DEEM™v.2005), thus minimizing the effort needed to move existing information into the LifeLine dietary assessments

Ability to enter data on residential exposure using either English or metric units
