  2. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    A study by Washington State published in 2011 found that the two largest sources of PCB flow into the Spokane River were City of Spokane stormwater (44%) and municipal and industrial discharges (20%). [174] PCBs entered the environment through paint, hydraulic fluids, sealants, inks and have been found in river sediment and wildlife.

    Ortho-PCBs may alter hormone regulation through disruption of the thyroid hormone transport by binding to transthyretin. [8] Coplanar PCBs are similar to dioxins and furans, both bind to the aryl hydrocarbon receptor (AhR) in organisms and may exert dioxin-like effects, in addition to the effects shared with non-coplanar PCBs.

    Historically, municipal and medical waste incineration was the most important source of PCDD/Fs. PCB-compounds, always containing low concentrations of dioxin-like PCBs and PCDFs, were synthesized for various technical purposes (see Polychlorinated biphenyls). They have entered the environment through accidents such as fires or leaks from ...

    [2] [3] For general population the most important source is food of animal origin like with other dioxin-like compounds. [ 4 ] [ 5 ] [ 6 ] The most relevant congener is 2,3,4,7,8-pentachlorodibenzofuran (2,3,4,7,8-PCDF) which is more toxic and based on relative toxicity more prevalent than other PCDFs.

  6. Lignan - Wikipedia

    Flax seeds and sesame seeds contain high levels of lignans. [1] [8] The principal lignan precursor found in flaxseeds is secoisolariciresinol diglucoside.[1] [8] Other foods containing lignans include cereals (rye, wheat, oat and barley), soybeans, tofu, cruciferous vegetables (such as broccoli and cabbage), and some fruits (particularly apricots and strawberries).

  8. Dioxin affair - Wikipedia

    en.wikipedia.org/wiki/Dioxin_Affair

    Later investigations revealed that the source of the contamination came from an oil-and-fat-recycling company, Verkest, from Deinze. The fats were reprocessed into animal feed that also contained transformer oil (coolant fluid), a known source of PCBs. Public concern about the quality of animal food in general became a hot issue in the media.

  9. Bioremediation of polychlorinated biphenyls - Wikipedia

    en.wikipedia.org/wiki/Bioremediation_of...

    Bioremediation of PCBs is the use of microorganisms to degrade PCBs from contaminated sites, relying on multiple microorganisms' co-metabolism. Anaerobic microorganisms dechlorinate PCBs first, and other microorganisms that are capable of doing BH pathway can break down the dechlorinated PCBs to usable intermediates like acyl-CoA or carbon ...
