Concept Introduction: The presence of containment in water makes the water polluted. All minerals and substances are permissible up to some level but higher dose can be lethal for human body.

Answer to Problem C15.2RE

Lead has zero tolerance level in drinking water because lead is harmful for human health even at low exposure levels and it has tendency to accumulate in body with time which can cause lethal effects like coma, and seizures.

Explanation of Solution

The presence of containment in water makes the water polluted. Calculated moles of containment provide information about their permissible limit in water which helps to determine the use of water.
