Antimony in Drinking-water WHO
The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in the periodic table (Wiberg, 1985). It is speculated that antimony could be a natural co-contaminant with arsenic in some drinking-waters (Gebel, 1999b). Soluble forms of antimony (and arsenic) tend to be quite mobile in water, whereas less soluble species
