  2. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    PCB-containing solid material was widely used as fill, including oxbows of the Housatonic River. Fish and waterfowl which live in and around the river contain significant levels of PCBs and are not safe to eat. [144] EPA designated the Pittsfield plant and several miles of the river as a Superfund site in 1997, and ordered GE to remediate the ...

  3. 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 ...

    Olestra was approved by the Food and Drug Administration for use as a food additive in 1996 and was initially used in potato chips under the WOW brand by Frito Lay.In 1998, the first year olestra products were marketed nationally after the FDA's Food Advisory Committee confirmed a judgment it made two years earlier, sales were over $400 million.

    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.

    A brown fat cell. Yellow adipose tissue in paraffin. White fat cells contain a single large lipid droplet surrounded by a layer of cytoplasm, and are known as unilocular. The nucleus is flattened and pushed to the periphery. A typical fat cell is 0.1 mm in diameter [2] with some being twice that

    PCDFs can be formed by pyrolysis or incineration at temperatures below 1200 °C of chlorine containing products, such as PVC, PCBs, and other organochlorides, or of non-chlorine containing products in the presence of chlorine donors. [1]

    The first-of-its-kind research found that a common chemical, musk ambrette, used to add scent to a wide range of products, may cause the body to release puberty-related hormones earlier than it ...

  9. Xenoestrogen - Wikipedia

    en.wikipedia.org/wiki/Xenoestrogen

    Xenoestrogens are a type of xenohormone that imitates estrogen.They can be either synthetic or natural chemical compounds.Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, BPA, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any ...
