Vic Chapter Meeting – Recording- Hard Surface Criteria & Sampling Case Study PFAS

Presenter(s): Ms Tarah Hagen, MSc, DABT, FACTRA Technical Director – Toxicology & Risk Assessment, SLR Consulting Australia Pty Ltd

Hard surface criteria and sampling – Case study PFAS

In certain situations, chemicals may be inadvertently deposited on surfaces within buildings which workers may come into contact with.

This presentation will cover the derivation of health-based hard surface swab criteria for per- and polyfluoroalkylated substances (PFAS) which can be used to judge the potential importance of this exposure pathway.

A general discussion will also be presented on the manner in which PFAS surface swab data can be collected and things to watch out for when interpreting the confidence in the analytical results.
