"Exposure to hexachlorobenzene occurs primarily from
eating low levels in contaminated food. The main health
effect from eating highly contaminated food is a liver
disease."
"Hexachlorobenzene was widely used as a pesticide
to protect the seeds of onions and sorghum, wheat,
and other grains against fungus until 1965. It was also
used to make fireworks, ammunition, and synthetic
rubber. Currently, there are no commercial uses of
hexachlorobenzene in the United States."

"Hexachlorobenzene is a white crystalline solid.
This compound does not occur naturally. It is
formed as a by-product during the manufacture
of chemicals used as solvents (substances used
to dissolve other substances), other chlorine-
containing compounds, and pesticides."
