A new computer program automates human health risk assessments (HHRAs) for combustion facilities, significantly reducing time and potential errors in environmental exposure modeling. This tool streamlines the process for the United States Army Center for Health Promotion and Preventive Medicine.

Area of Science:

  • Environmental Science
  • Risk Assessment
  • Computational Toxicology

Background:

  • The United States Environmental Protection Agency (USEPA) established a screening methodology for indirect exposure risk assessments in 1994.
  • Human health risk assessments (HHRAs) are crucial for evaluating environmental contaminant exposure from combustion facilities.
  • Current HHRA methods involve complex spreadsheet models, leading to time-consuming quality assurance/quality control (QA/QC) processes.

Purpose of the Study:

  • To develop a computational tool to automate and expedite the HHRA process.
  • To minimize human error associated with manual data entry and calculations in risk assessments.
  • To improve the efficiency of environmental exposure modeling for combustion facilities.

Main Methods:

  • Development of a Microsoft Excel-based computer program.
  • Implementation of a structured 6-step development process: problem understanding, spreadsheet structure, algorithm development, coding, program execution, and result testing.
  • Automation of contaminant concentration estimation and risk/hazard prediction for exposed individuals.

    • Main Results:

    • The developed program significantly reduces the time required for HHRA spreadsheet verification.
    • Automated calculations ensure values are placed correctly, minimizing data entry errors.
    • The program streamlines the estimation of environmental contaminant concentrations and associated health risks.

    Conclusions:

    • The automated program offers a substantial time-saving solution for conducting HHRAs.
    • This computational approach enhances the accuracy and reliability of risk assessments.
    • The tool supports efficient and effective public health and environmental protection efforts.
