Vinyl Chloride
Vinyl chloride monomer is used to make PVC piping among other things. Vinyl chloride is sweet smelling and was used in the 1950s and 1960s as a vehicle in spray paints and hair sprays. Workers who make vinyl chloride or PVC piping are subjected to the vapors of vinyl chloride as well as the hairdressers who were exposed to very significant concentrations of vinyl chloride when it was a component of hair spray. Both have experienced the carcinogenic effects of vinyl chloride.
Vinyl chloride is a human carcinogen causing a rare liver cancer called angiosarcoma. It has been shown to cause other liver cancers and possibly brain and lung cancers. Vinyl chloride is a vascular toxin, and can not only cause the vascular liver cancer called angiosarcoma, but can also disrupt blood flow to the extremities, causing a deterioration of bone resulting in a condition called acroosteolysis, the dissolution of bone. This conditions begins with a numbing of the fingertips followed by their disfigurement as a result of bone loss.
Dr. Parent has studied the effects of vinyl chloride on animals and man and has constructed a time line of knowledge related to the carcinogenic effects of vinyl chloride. This time line is based on published literature and internal company documents and demonstrates a deliberate action by industry to conceal the fact that vinyl chloride is carcinogenic. He has written causation reports relating vinyl chloride exposure to angiosarcoma. Dr. Parent’s office has a data base of more than 600 peer-reviewed publications on vinyl chloride.
