The Application of PAH Bioaccessability Testing to Assess the Human Health Impacts at Former Gasworks Sites
Dr. Darren Beriro
Darren currently works as an environmental geochemist at the British Geological Survey, UK. Darren recently gained a PhD from the University of Nottingham which focused on the predictive numerical modelling of human ingestion bioaccessibility of organic compounds in soil. Before embarking on his research career, Darren worked in industry on land contamination projects for nearly 10 years. Darren’s interest remains largely with organic bioaccessibility and data-driven modelling, with a focus on how research is applied to the risk-based management of land contamination.
The quantification of PAH ingestion bioaccessibility at former MPG sites can be undertaken using a number of recently developed methods. Despite these developments, the tests are not routinely used in risk-based land management. This presentation will explore the following questions: what is bioaccessibility and how is it measured; why is ingestion bioaccessibility testing for PAH soil not widely utilised in risk assessment; what are the potential benefits of developing new bioaccessibility tests for the inhalation and dermal pathways; what developments in the state-of-the-art might we expect over the next ten years.
