Dr. Clark recommends Spectrum Chemical of Gardena, CA, for pure baking soda, i.e., free of benzene. Dr. Clark also warns against using health brands as they are more likely than not to be contaminated with benzene.
Dr. Clark offers a partial solution for the dilemma; she says a minute amount of HCI can detoxify traces of benzene in water. Further, she recommends taking 600 mg of vitamin B2 with each meal to reduce benzene buildup. "Coriander oil is an essential oil that can oxidize PCBs and benzene in a slow and steady way."
As you read the excerpt from wikipedia, you will see benzene is used as an intermediate to make other chemicals; rather notable is its use in the production of drugs and plastics.
http://en.wikipedia.org/wiki/Benzene
Benzene, also known as benzol, is an organic chemical compound with the formula C6H6. It is sometimes abbreviated Ph-H. Benzene is a colorless and flammable liquid with a sweet smell and a relatively high melting point. It is carcinogenic and its use as additive in gasoline is now limited, but it is an important industrial solvent and precursor in the production of drugs, plastics, synthetic rubber, and dyes. Benzene is a natural constituent of crude oil, but it is usually synthesized from other compounds present in petroleum. Benzene is an aromatic hydrocarbon and the second [n]-annulene ([6]-annulene), a cyclic hydrocarbon with a continuous alternation of single and double bonds. Today benzene is mainly used as an intermediate to make other chemicals. Its most widely-produced derivatives include styrene, which is used to make polymers and plastics, phenol for resins and adhesives (via cumene), and cyclohexane, which is used in the manufacture of Nylon. Smaller amounts of benzene are used to make some types of rubbers, lubricants, dyes, detergents, drugs, explosives and pesticides.
