QUARTERLY WEBINAR
Accounting for Mobility in Alternatives Assessments Insights from the ZeroPM Project
![]() |
June 8, 2023 In this A4 webinar, you will hear from the ZeroPM project and its work to advance the accounting of substance mobility attributes in alternatives assessment processes. Presenters will provide an overview of the ZeroPM project; the persistent, mobile and toxic (PMT) and very persistent, very mobile (vPvM) hazard criteria that have been recently adopted by the European Commission as part of the revision to the Classification Labeling and Packaging (CLP) regulation; the utility of essential use and substance grouping concepts as it relates to PM substances and considerations for alternatives assessments, using chemicals used as flame retardants and cosmetics as a case study; and looking forward the use of “big data” approaches to identify functional alternatives for prioritized PM substances. |
