Webinar 29 | Using CLEA for Human Health DQRA

This webinar will be delivered by Simon Firth and has been designed to follow on from SoBRA's Introduction to CLEA webinar from April 2022. It will provide greater detail on the principles behind the CLEA model and how it can be used for conducting DQRA for human health. The webinar will use worked examples (for lead, hexavalent chromium and TCE soil contamination) to illustrate how CLEA might be used for DQRA in different situations. The webinar will include a brief introduction to toxicology and give pointers on where to find health based guidance values. It will also give some specific advise to those working in Scotland.
