Some swimming pools use a borate buffering system. Borates lower the level
of carbon dioxide in the pool, which slows algae growth. This results in a lower
chlorine requirement. Free chlorine levels in pools with borate systems can be
maintained at 1.0 ppm.
Small amounts of boron are necessary for plant growth but large amounts can be
toxic. In humans, boron aids in the uptake of calcium and the production of strong
bones. An excess of boron can affect the central nervous system resulting in a
syndrome known as borism. Some natural waters may contain small amounts of
boron. Large concentrations may be due to industrial effl uent entering waterways.
Boron compounds are used in cleaning compounds, paper and paints, fertilizers,
glass and ceramics, fi re retardants and the production of alloys. In the atomic
energy fi eld, boron is a component of neutron shields and nuclear reactors.
