Asbestiform riebeckite (crocidolite) dissolution in the presence of Fe chelators; implications for mineral-induced disease

X-ray photoelectron spectroscopy (XPS) and solution chemistry were used to monitor the changes in surface composition of crocidolite fibres in a 50 mM NaCl solution at pH 7.5 and 22°C in the presence of several Fe chelators (citrate, EDTA, or desferrioxamine) for up to 30 days.
