The nature of corrosion products in lead pipes used to supply drinking water to the City of Glasgow, Scotland, UK.
International Conference on Trace Element Speciation in Biomedical Nutritional and Environmental Sciences. Neuherberg near Munich, DEU, 1998/05/04.
Corrosion products, obtained from lead service pipes carrying the public drinking water supply to the Glasgow area, have been characterised by FTIR spectrometry, powder x-ray diffraction spectrometry, flame atomic absorption spectrometry and ion chromatography.
As expected, the products which formed in the presence of pH adjusted-water were mainly lead carbonate or basic lead carbonate.
Products from areas where the water supply had been treated with orthophosphoric acid and pH adjustment for up to eight years also contained a variable proportion (up to ~30% w/w) of a phosphate species.
This has been identified as an apatite, most probably lead hydroxyapatite, Pb5 (PO4) 3OH.
