Mineral constituents of health significance of Hazara water supplies

One hundred water samples collected from different water supply sources in Hazara Division were analysed for their mineral constituents.

Fluorides and iodides were either absent in some samples or were in very low concentrations indicating a possible correlation with the mottling of teeth in children and a high incidence of endemic goitre in the hilly areas of Hazara Division
