Entwistle J

My involvement in Applied/Environmental Geochemistry has developed over the years with a recent and on-going focus on the bioavailability and bioaccessibility of potentially harmful elements (PHEs) in the urban environment. My recent work has focused on the inhalation and oral ingestion pathways, developing, refining and applying physiologically based in-vitro extraction protocols as part of human health risk assessments on brownfield land and public open space.

 The application of bioaccessibility protocols is where research data are still lacking and where my work (and that of my PGR students and geochemistry research collaborators) has been able to make a substantive contribution. This work has also involved method development (e.g. in-vitro lung extraction fluids and protocol) and application at multiple sites in the UK and beyond.

A key feature of my current activity is to understand the solid-phase partitioning of PHEs in soil (using sequential chemical extraction and scanning electron microscopy) as a driver of both pragmatic risk assessments but also to better target suitable remediation measures.
