Theme 1: Project 5 - Low level population heavy metal exposure
“Contaminated land” is a recognised problem for areas of the UK with some previous industrial and brown field sites having persistent high levels of metals and other contaminants. The potential importance of population exposures for health, particularly infant health, has recently been highlighted in work by the Committee on Toxicity but there are uncertainties relating to current population exposure levels. Imperial College have recently obtained a comprehensive data set from the British Geological Society with extensive sampling of soil concentrations of metals, but these are at different resolutions. PHE is contributing to the COST Action IS1408 “Industrially Contaminated Sites and Health Network” (ICSHNet), which is assembling Europe-wide data on health risks potentially associated with industrially contaminated land. This work will update UK population exposure assessment for use in risk assessment.
