However, for these heavy metals either essential or toxic the health risk requirement requires consideration of toxicity from excessive exposure.

Pathogens present in drinking water including many viral, bacterial, and protozoan agents caused 2. The fluoride concentration in various drinking water samples collected from tap and wells water in Quetta indicated that all samples were within permissible limits of WHO except one sample of tap water [ 93 ].
