Analysis of Dioxins and Furans

HomeServicesFSSAI APPROVED TESTING LABAnalysis of Dioxins and Furans

Dioxins and furans are highly toxic environmental pollutants belonging to the group of persistent organic pollutants (POPs). The term “dioxins and dioxin-like substances” commonly refers to polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs). PCDD and PCDFs are environmental contaminants detectable in almost all compartments of the global ecosystem in trace amounts. These compounds can originate from various industrial processes, such as waste incineration, chemical manufacturing, and paper bleaching. They are formed as by-products of numerous industrial activities and all combustion processes. Besides the anthropogenic sources of PCDD/PCDF, an enzyme-mediated formation of PCDD and PCDF from 2,4,5- and 3,4,5-trichlorophenol has been demonstrated to be responsible for their biogenic formation. Due to their persistence and ability to bio-accumulate, dioxins and furans pose significant health risks to humans and wildlife, making their detection and control critical.

The detection of dioxins and furans is essential to ensure environmental safety and public health.

  • Dioxins and dioxin-like PCBs are fat soluble and tend to bio-accumulate in body fat, both in animals and humans, accumulating through the food chain.
  • Dermal toxicity such as Chloracne
  • Immunotoxicity
  • Reproductive effects and teratogenicity
  • Endocrine disrupting effects
  • Carcinogenicity

 

Regulatory agencies worldwide have established stringent limits for dioxin and furan levels in various environmental matrices, food products, and industrial emissions. Regular monitoring and accurate detection of these contaminants are vital for compliance with environmental regulations and for protecting human health.
