Polyvinyl chloride (PVC) is a widely-used plastic. In terms of revenue generated, it is one of the most valuable products of the chemical industry. Globally, over 50% of PVC manufactured is used in construction. As a building material PVC is cheap, and easy to assemble. In recent years, PVC has been replacing traditional building materials such as wood, concrete and clay in many areas. Despite appearing to be an ideal building material, PVC has high environmental and human health costs.

Polyvinyl chloride is produced from its monomer, vinyl chloride (chemical formula CH2=CHCl). PVC is a hard plastic that is made softer and more flexible by the addition of phthalates (plasticizers).

There are many uses for PVC including vinyl siding, gramophone records (hence the ones made of this material are sometimes called vinyl records) pipe/plumbing/conduit fixtures, bean bags; and, in its soft form, for clothing, upholstery (car seats), etc.


Polyvinyl chloride was accidentally discovered on at least two occasions in the 19th century, first in 1838 by Henri Victor Regnault and in 1872 by Eugen Baumann. On both occasions, the polymer appeared as a white solid inside flasks of vinyl chloride that had been left exposed to sunlight. In the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC in commercial products, but difficulties in processing the rigid, sometimes brittle polymer blocked their efforts.

In 1926, Waldo Semon of B.F. Goodrich developed a method to plasticize PVC by blending it with various additives. The result was a more flexible and more easily processed material that soon achieved widespread commercial use.

Dangers of PVC

Most vinyl products are believed to be generally harmless when used properly. However, some of the additives and softeners leach out of certain vinyl products. Even though soft PVC toys have been made for babies for years, studies find that these additives leach out of soft toys into the mouths of the children chewing on them. Vinyl IV bags used in neo-natal intensive care units have also been shown to leach DEHP (di-2-ethyl hexyl phthalate), a phthalate additive. In Europe, phthalate additives in PVC toys for children under the age of three have been banned and in the USA, most companies have voluntarily stopped manufacturing PVC toys for this age group or have eliminated the phthalates. However, alternative softeners have not been properly tested to determine whether they are safe. Other vinyl products like brand new car interiors, shower curtains, and flooring, to name a few, initially release chemical gases into the air. Some studies indicate that this outgassing of additives may contribute to health complications, but the information on this is preliminary and needs further study.

According to some medical studies, the plasticizers added to PVC may cause chronic conditions such as Raynaud's syndrome, scleroderma, angiosarcoma, brain cancer and acroosteolysis.

In the late 1960's, Dr. John Creech, and Dr. Maurice Johnson, were the first to clearly link and recognize the carcinogenicity of vinyl chloride monomer to humans; workers in the polyvinyl chloride polymerization section of a B.F. Goodrich plant near Louisville, Kentucky, were diagnosed with liver angiosarcoma, a rare disease. Since that time, studies of PVC workers in Australia, Italy, Germany, and the U.K. have all associatied occupational cancers with exposure to vinyl chloride.

The environmentalist group Greenpeace has advocated the global phase-out of PVC because dioxin is produced as a byproduct of vinyl chloride manufacture.
