Dioxins and PCBs: how are they classified
Dioxins – toxic legacy of industrial processes
Dioxins, or polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs), are a group of highly toxic, persistent organic pollutants (POPs) formed as unintentional by-products in industrial and combustion processes involving chlorine. Of the 210 known congeners, 17 are particularly toxic, with 2,3,7,8-TCDD being the most toxic, classified as carcinogenic to humans by the World Health Organization (WHO). Dioxins are chemically and thermally stable, fat-soluble, and resistant to biological degradation. As a result, they accumulate in the food chain – mainly in meat, eggs, dairy products, fish and shellfish – posing long-term health risks to humans through dietary exposure.
PCBs – Industrial chemicals with lasting impact
Polychlorinated biphenyls (PCBs) are a group of 209 synthetic chlorinated compounds that were widely used in industrial applications. Although banned in many countries, they persist in the environment and food chain, where they accumulate, particularly in animals. In recent years, it has also been found that PCBs can be formed as unwanted by-products in industrial processes. Of the 209 congeners, 12 show toxicological properties similar to dioxins and are classified as dioxin-like PCBs (DL-PCBs), while the remaining are referred to as non-dioxin-like PCBs (NDL-PCBs). Both types pose significant health risks, including endocrine disruption, immune system impairment and potential carcinogenicity. Due to their widespread historical use and environmental persistence, PCBs remain a critical focus of food and feed safety monitoring.
