Academy of Sciences to improve AA decisions by including comparative xposure assessment, the HESI Sustainable Chemical Alternatives Technical Committee, which consists of scientists from academia, industry, government, and
NGOs, has developed a qualitative comparative exposure approach. Conducting such a comparison can screen for alternatives that are expected to have a higher exposure potential, which could trigger a higher-tiered, more-quantitative exposure assessment on the alternatives being considered.
This talk will demonstrate an approach for including chemical and product exposure information in a qualitative AA comparison. Starting from existing hazard AAs, a series of four exposure examples were examined to test the
concept, to understand the effort required, and to determine the value of exposure data in AA decision-making. The group has developed ingredient and product parameter categorization to support comparisons between chemicals and methodology to address data quality. The ingredient parameters include a range of physicochemical properties that can impact exposure, while the product parameters include aspects such as exposure pathway, use pattern,
frequency/duration of use, concentration in product and use volume, accessibility, and disposal. Key learnings, challenges, and opportunities for further work will also be presented.
