Title Change in cement manufacturing process, a cause for decline in chromate allergy?
Bibliographic information Jan. 1996, Vol.34, No.1, p.51-54. 19 ref.
Abstract The concentrations of hexavalent chromate (CrVI) in the constituents of four brands of cement and in manufactured cement samples were determined. Results indicated that increasing the concentration of slag (free from CrVI) over clinker (high in CrVI) proportionally reduced the CrVI concentration of the cement; this reduction is due to the dilutional effect of slag over clinker. It is suggested that the general decline in the prevalence of chromate allergy in recent years in Singapore is due to a change in the constituents of cement, resulting in lower concentrations of hexavalent chromate.
