Although dioxin existed at low part-per-million levels in the herbicide mixture, the extreme toxicity of this contaminant in certain species created grave concern for contaminated areas. This concern led to a ban on the use of the herbicide 2,4,5-trichlorophenoxyacetic acid because TCDD is formed through a condensation reaction involving two molecules of 2,4,5-trichlorophenol. While the EPA banned a more harmful bleaching process back in 1998, current elemental "chlorine-free" bleaching processes using chlorine dioxide still produce, albeit less, dioxins.
