Question:

60 Mr. Sargent asked the Minister for Health if the fluoride in liquid form, hydro fluorisidicic acid, is a by-product of the super phosphate fertiliser industries. [8412/96]

,Limerick East): I assume the Deputy is referring to hydrofluosilicic acid, otherwise known as fluosilicic acid.

Hydrofluosilicic acid is one form in which fluoride/s are available. Others include sodium fluoride and sodium-silico fluoride. All are obtained either as (a) primary products only or as (b) byproducts of the fertiliser industry.
