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 aff ect 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. Some swimming pools
use boron buff ering systems.
