PCBs biomagnify up the food web and are present in fish and overflow of contaminated aquifers. [57] Human infants are exposed to PCBs through breast milk or by intrauterine exposure through transplacental transfer of PCBs [56] and are at the top of the food chain. [58]: 249ff
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.
Human exposure to dioxins and DLCs is a cause for public and regulatory concern. [5] Health concerns include endocrine, developmental, immune and carcinogenic effects. [ 12 ] The route of exposure is primarily through the ingestion of animal products such as meat, dairy, fish, and human breast milk. [ 12 ]
PCBs are toxic to fish at high doses, and associated with spawning failure at low doses. Human exposure occurs through food, and is associated with reproductive failure and immune suppression. Immediate effects of PCB exposure include pigmentation of nails and mucous membranes and swelling of the eyelids, along with fatigue, nausea, and vomiting.
The amount of "meat" is equivalent to that of all 7 billion humans on the planet combined. Spiders could, theoretically, eat every single human on earth within one year. It gets worse.
Polychlorinated biphenyls (PCBs), derived from biphenyl, of which 12 are "dioxin-like". Under certain conditions PCBs may form dibenzofurans through partial oxidation. Polybrominated analogs of the above classes may have similar effects. "Dioxin" can also refer to 1,4-dioxin or p-dioxin, the basic chemical unit of the more complex dioxins. This ...
When you eat spicy food, the capsaicin binds to receptors in the mouth and on the tongue called TRPV1, says Terry. "These send signals of pain to the brain," he adds. Technically, spiciness is ...
Photos of cannibals around the world: In India, exiled Aghori monks of Varanasi drink from human skulls and eat human flesh as part of their rituals to find spiritual enlightenment.
