About the Event

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.

Simon is an independent environmental consultant with 27 years’ experience in land contamination. Starting out as a hydrogeologist he has since developed significant expertise in human health and environmental risk assessment both in the UK and internationally. Simon routinely conducts and peer reviews land contamination risk assessments and is a scrutineer for SoBRA's risk assessor accreditation scheme. He has been instrumental in the development of published generic soil and groundwater screening values for protection of human health in the UK (including the C4SLs and SoBRA GAC) and has contributed to various UK guidance documents on risk assessment.
