Answer:
Explanation:1. PH its acid-base balance, is the level of acids and bases in your blood at which your body functions best.
Its a PH problem because it can lead to two conditions: acidosis and alkalosis.
[ 2. Factors and causes Carbon Dioxide. When dissolved in water, carbon dioxide forms a weak acid that can throw off the balance of the pH.
Acidics and Akalines.
Sodium and Calcium Hypochlorite.
Chlorine.
Air-borne Contaminants.
Air Pollution.
Causes are:
The degree of change depends on the alkalinity of the water.
In the body
There fore,
Carbon dioxide is the most common cause of acidity in water.
A higher pH level can also be caused by a sudden rise in temperature of the water.
While
Low blood pH because of kidney disease or kidney failure is called metabolic acidosis. This happens when the kidneys don't work properly to remove acids from your body. This raises blood acids and lowers blood pH.
3. Examples of public health problems .Alcohol-related harms.
Food safety.
Healthcare-associated infections.
Heart disease and stroke.
HIV.
Motor vehicle injury.
Nutrition, physical. activity and obesity.
Prescription drug. overdose.
