Boron in Water
Boron (B) occurs as sodium borate (borax) or as calcium borate (colemanite) in mineral deposits and in natural waters. It is never found in nature in its elemental form.
Boron is usually found in low concentrations in surface waters and is usually present around igneous rock formations.
Boron has many beneficial functions in biological, metabolic and physiological processes for plants and animals. It plays a vital role in maintaining animal health and preventing nutritional disorders.
Trace levels of Boron play an important role in cell membrane function, enzymatic reactions, hormonal and mineral metabolism of animals and humans.
Boron compounds have a wide range of physiological effects in living organisms when occurring at low levels, while toxic at high levels. Boron does not accumulate efficiently in soft tissues; but it accumulates efficiently in the bones.
Boric acid can be toxic to fresh water fish, however, the reported concentrations are quite high.
Boron has been confirmed to be an essential element for plant growth.
