LifeLine Community Based Assessment Software™ Version 1.0


The LifeLine C-BAS™ Software provides a tool for those interested in the public health of any community (population level, down to individual community level) to utilize the valuable array of existing information and complete an exposure/risk assessment for that community of interest. Of note, this tool makes visible the link between occurrence of chemicals in food and environment and people’s exposure; describing who is exposed, how often, and how much. When combined with health effect information, the tool can show the link between exposure and potential health consequences for those people in the community and the potential consequences of exposure reduction strategies.

Accurately predicting risk starts with accurately assessing exposure. That means understanding and displaying profiles of:

  • Who is exposed (age group, gender, other demographics of importance)
  • What is the magnitude of that exposure for different parts of the population
  • What is the duration of the exposure and its periodicity of repetition
  • What are the driving routes (oral, dermal, inhalation) and sources of the exposure

For the health professional and decision-maker, these are critical questions, which they would like to have answered before proceeding to the risk assessment. A tool such as the LifeLine C-BAS™ that can delineate these characteristics of exposure in the community can inspire ideas for risk reduction strategies and focus attention on the important exposure sources.

Information needed in order to conduct a community specific exposure and risk assessment using The LifeLine C-BAS™ includes

  • Information about the people in the population, including height/weight relationships of the population
  • Information about dietary habits (as described by LifeLine DRG™ file(s))
  • Information about activity profiles (as described by a LifeLine ARG™ file)
  • Monitoring or residue data describing the concentration and where the substance of interest (chemical, contaminant, nutrient, or other) is found in the diet, water source, and/or living environment.
  • Sources of water
  • General information describing the influences on the community that create distinct subpopulations (male/female, age groups, economic, housing, employment, rural/urban living, etc). Such general information informs the assessor at several points when using the software.
  • Health effect information related to the substance of interest (this is needed specifically if the assessor wants to conduct a risk assessment)
