There has been a dioxin controversy about the health and environmental effects of dioxins for more than 20 years.[1][2]
Dioxins are by-products of many industrial processes including waste incineration, chemical manufacturing, chlorine bleaching of pulp and paper, and smelting. Any process "in which chlorine and organic matter are brought together at high temperatures can create dioxin". It is for this reason that "Greenpeace and other environmental groups have called for phasing out of the chlorine industry".[2][1][3] However, chlorine industry supporters say that "banning chlorine would mean that millions of people in the third world would die from want of disinfected water".[4]
One of the key players in the dioxin controversy has been the Dow Chemical Company. Dow is a large manufacturer of chlorine, producing an estimated 40 million tons of chlorine each year, much of which is used to make plastics, solvents, pesticides and other chemicals. In 1965 "a Dow researcher warned in an internal company document that dioxin 'is extremely toxic' but Dow has always publicly claimed it is not".[2]
Sharon Beder and others have argued that the dioxin controversy has been very political and that large companies have tried to play down the seriousness of the problems of dioxin.[3][1][5] The companies involved have often said that the campaign against dioxin is based on "fear and emotion" and not on science.[6]
