CEPST™ Highlights

Key Features in Developing the Lifeline Chemical Exposure Priority Setting Tool™ (CEPST™)

• Appropriate to large number of widely varying substances
• Yields highest plausible exposure (or risk) measures for substances in products scenarios or environmental media
• Requires a low effort per chemical
• Can be consistently applied
• Uses substance-specific and user-specific data sets to perform the exposure estimates
• Identifies Sentinel Products matched to scenarios and scenario-specific algorithms predictions of dermal, oral and inhalation exposure
• Uses open methodology, disclosure of all assumptions and algorithms and can be based on publicly available data
• Provides quantitative estimates of highest plausible exposures sorted separately by route, any age grouping or duration (e.g., acute, sub-chronic and chronic).
