Assessing the human health risks posed by chromium-contaminated land in Glasgow and its environs

摘要

Like many cities throughout the UK, Glasgow has a long history of bothudurbanisation and industrialisation, resulting in elevated concentrations of potentiallyudharmful elements (PHEs). Between 1830 and 1968 Glasgow was home to one of theudworld’s largest producers of Cr-based chemicals. Chromite ore processing residueud(COPR) arising from the factory was used as infill material across large areas of SEudGlasgow, resulting in widespread land contamination with Cr(VI), a known humanudcarcinogen of significant mobility. A recent survey by the British Geological Surveyud(BGS) of Glasgow and its surrounding urban environment has highlighted numerousudsites with total Cr concentrations exceeding soil guideline values (SGVs) generated byudthe Contaminated Land Exposure Assessment (CLEA) model.
