What Is Cyanide?

  • Cyanide is a carbon-nitrogen chemical unit and can be produced naturally and artificially.
  • Certain bacteria, fungi, and algae can form cyanides.
  • It is also found in a number of foods and plants such as stone fruits, lima beans, fiddle heads and almonds.

Uses of Cyanide.

  • Cyanide is also used in electroplating, photographic development, making plastics, mining processes, and herbicides.
  • It is also released in car exhaust.

How Does Cyanide Get Into Water?

  • Cyanide can be released into groundwater and soil from natural processes.
  • Very small amounts of cyanide can be toxic to aquatic life.
  • Mining can also be a source of cyanide pollution to ground and surface water. 

Health effects of Cyanide on humans.

  •  Cyanide is a fast-acting poison.
  • Cyanide is very poisonous and ingesting high levels of cyanide may cause breathing difficulties, convulsion, loss of consciousness, brain and heart damage, or even coma and death.
  • Ingesting lower levels of cyanide over the long term may increase blood cyanide level, which will show toxic effects such as weakness of the fingers and toes, difficulty walking, dimness of vision, deafness, and decreased thyroid gland function.
  • It may also change the metabolism in adults and slowing growth or development in children.
  • Other Considerations:
    • There are medical tests to show whether you have been exposed to cyanide.
    • Doctors can measure cyanide levels in the blood, and urine; however, small amounts of cyanide are always detectable.
    • An almond-like in the breath may indicate that person was exposed to cyanide.
    • Seek a medical advice if you think you may be exposed.
    • Studies have shown that cigarette smokers generally have higher cyanide-related compound levels in their blood levels. 

Removing Cyanide From Water source.

  •  Cyanide can be removed from water by demineralization through the use of ion exchange, reverse osmosis, and oxidation by chlorine followed by filtration.
