As mentioned, in the 1990’s 2,4,5-T was banned in Australia. 2,4-D was permitted, as it has much lower levels of dioxin than 2,4,5-T due to the way it is manufactured. The 2005-10-02 In addition, the Government is continuing to carry out food monitoring activities to identify, control and if possible, eliminate previously unknown sources of dioxin contamination. Also, Health Canada is doing a comprehensive reassessment of the risks posed by dioxins. 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.

Additionally, dioxin is linked to type 2 diabetes, immune system • Dioxin concentrations in PCNB are comparable to those known from the banned pesticides 2,4,5-T (trichlorophenoxyacetic acid; the key ingredient of Agent Orange). Note: TEQ concentrations in PCNB are at the lower end for those known for 2,4,5-T (approaching the 7,000 µg/tonne used under the Stockholm Convention to estimate historical dioxin releases via past use of 2,4,5-T). 2009-11-08 Dioxins uncovered.
