The trace elements are chemical particles - metals or metalloids - whose clusters are needed in small quantities in the body of an organism (usually 100 parts per million). Also called micronutrients or compounds. Trace elements exist in all waters - potable, mineral and marine.
Rainwater, when crossing the atmosphere, is carried, albeit sparingly, of trace elements in its performance from the clouds to the ground. Main trace elements in mineral waters: bismuth, boron, bromine, cadmium, cobalt, copper, tin, strontium, gallium, germanium, iodine, lithium, manganese, selenium, titanium, tungsten, vanadium and zinc.
The mineral water bioleve is considered an oligomineral water, because it contains several types of salts, all in low concentration.
