PCBs had widespread use in numerous industrial applications, and were produced in large quantities for several decades with an estimated total world production of 1.2-1.5 million tonnes, until they were banned in most countries by the 1980s. Dioxins and PCBs are found at low levels in many foods.

Dioxin is a carcinogen and has been linked to different types of cancer. In fact, triclosan can manifest itself in the body as a producer of uncontrolled cell growth. Combined with chlorinated, toxic tap water , it forms chloroform, another cancer causer.

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. If my dioxin levels are elevated should I go to even greater lengths to limit my exposure in future?

PCBs had numerous industrial applications before being banned in the EU by the 1980s. Twelve PCBs are referred to as “dioxin-like PCBs” as they share toxicological properties with dioxins. For more information see our Topic on Dioxins and dioxin-like PCBs. 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.

19 Jul 2007 The term “dioxins” is often used in a confusing way. many countries decided in the 1970s to ban the use of PCBs in open applications.

The crux of the matter is that dioxin effects occur in two distinct areas – low-dose direct effects, which interfere with development, and high-dose indirect effects, such as lethal cancers. 2004-05-16 Dioxin poisoning encompasses toxic effects of acute and chronic exposure to one or more of chemicals belonging to the dioxin group. Although environmental low dose exposure over a long period of time is the most common scenario, an acute, high-dose exposure is the most relevant from a diagnostic point of view, since it shows clear clinical signs, such as chloracne.… 2010-04-22 Despite being banned from production for decades, polychlorinated biphenyls (PCBs) continue to pose a significant risk to human health. This is due to not only the continued release of legacy PCBs from PCB-containing equipment and materials manufactured prior to the ban on PCB production, but also the inadvertent production of PCBs as byproducts of contemporary pigment and dye production.

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.
