Classification of natural mineral waters based on a fixed residue at 180°C

Fixed residue at 180°CDefinition
Fixed residue at 180°C:
< 50 mg/L
Definition:
Very low mineral content water (or light mineral water)
Fixed residue at 180°C:
50–500 mg/L
Definition:
Low mineral content water
Fixed residue at 180°C:
500–1500 mg/L
Definition:
Medium mineral content water
Fixed residue at 180°C:
> 1500 mg/L
Definition:
Rich mineral content water

Macronutrients present in the human body in modest quantities

CalciumBone development, regulation of muscle contraction and myocardium activity, blood clotting, nerve impulses transmission, regulation of cell permeability.
ChlorineHydrochloric acid formation (digestive juices for digestion process).
PhosphorusProtein synthesis, ATP synthesis and transport of energy in biological systems.
MagnesiumBone formation, nervous and muscular activities, lipid metabolism and protein synthesis, CVD protection.
PotassiumMuscles and myocardium activities, neuromuscular excitability, acid-base balance, water retention and osmotic pressure.
SodiumFundamental regulation of cell permeability and body fluids; deficiency is rare, but an excessive intake may be associated with high blood pressure.
SulphurEssential amino acids, cartilage, hair and nails formation, enzyme activity in redox processes and cellular respiration, intestinal peristalsis.

Micro-nutrients trace elements, essential for some biological functions

CobaltConstituent of vitamin B12: growth factor, nucleic acid synthesis and haematopoiesis.
ChromiumEnzymatic reactions involved in the metabolism of carbohydrates, lipids and proteins.
IronBlood and muscle tissues: haemoglobin, myoglobin.
FluorineProtection and prevention of tooth decay, bone development; diseases related to excess.
IodiumEssential for the synthesis of hormones that are involved in the growth process and body development.
ManganeseSynthesis of several enzymes involved in the metabolism of proteins and sugars, bone development.
MolybdenumProduction of enzymes associated to uric acid.
CopperFunctionality of several enzymes in blood and muscles.
SeleniumProtection of the muscle membrane integrity, antioxidant.
