Episode 12: Approaching variable data when assessing substance mobility - with Sivani Baskaran
Live from SETAC Europe 2023 - Raoul Wolf hosts a series of ZeroPM podcasts. In this episode he interviews Sivani Baskaran (Norwegian Geotechnical Institute) about the how to assess mobility in relation to the new chemical hazard classes PMT and vPvM. Chemical hazard and risk assessments often use
physical-chemical properties to categorize and identify chemicals of concerns. Recently, the European Commission introduced a draft revision of the classification, labelling and packaging (CLP) legislation that contained new chemical hazard categories, including persistent, mobile, and toxic (PMT) and very persistent and very mobile (vPvM) substances. Persistence is derived from the simulated half-life of a chemical in different systems (aquatic, soil, and sedimentary), depending on the compartment and degree of persistence evaluated, while mobility is determined based on the logarithmic organic carbon–water partition ratios (log Koc). But what is to be done when the log Koc data is either variable or uncertain? Sivani presents a way forward using a Bayesian approach.
