As the principal spokesman for an industry committed to responsible care, [I can say] it is disturbing to our members that the April 28 front page article ``Greenpeace charges vinyl study tainted,'' conveys such a negative and false impression concerning PVC.
Vinyl plastic is a material that can be produced safely, used safely and disposed of safely. More than half a century of increasing use proves that conclusively. The American Society of Mechanical Engineers study of incineration mentioned in your article was extensively peer-reviewed by scientists, engineers and statisticians and concluded that there is no significant relationship between chlorine in incinerator feeds and dioxin emissions.
Worldwide expansion of the vinyl industry, based upon public demand for its products, has been going on for 60 years and studies show that since 1970, dioxin in the environment has declined while vinyl production has tripled. It's time to agree that the ``dioxin problem'' is well on its way to being solved.
The tired and discredited attack on vinyl coming from some quarters totally ignores the fact that vinyl makes a very major contribution to society. The vinyl industry is establishing a strong, pro-environment record and no false attacks can get in the way of that truth.
