Aldrin, Chlordane, DDT, Dieldrin, Dioxins, Endrin, Furans, Heptachlor, Mirex, Toxaphene, Hexachlorobenzene (HCB), and Polychlorinated Biphenyls (PCBs)
The Stockholm Convention has banned Dioxin (TCDD) and Hexachlorobenzene (HCB), they cause cancer and dozens of other painful & disabling diseases, utlimately ending in early deaths for the many poisoned.
The chemicals known as persistent organic pollutants act as powerful herbicides/pesticides and serve a range of industrial purposes. Some POPs are also released as unintended by-products of combustion and industrial processes.
While the risk level varies from POP to POP, by definition all of these chemicals share four properties:
1) They are highly toxic;
2) they are persistent, lasting for years or even decades before degrading into less dangerous forms;
3) they evaporate and travel long distances through the air and through water; and
4) they accumulate in fatty tissue.
This is a dangerous combination. The persistence and mobility of POPs means that they are literally everywhere in the world, even in the Arctic, Antarctica, and remote Pacific islands.
Their attraction to fatty tissue, known as "bioaccumulation", means that even though a poison is first dispersed widely and thinly it gradually starts to concentrate as organisms consume other organisms as they move up the food chain.
The chemicals reach magnified levels – up to many thousands of times greater than background levels – in the fatty tissues of creatures at the top of the food chain, such as fish, predatory birds, and mammals, including human beings.
Worse still, during pregnancy and breastfeeding these POPs are often passed on to the next generation. Human beings and other mammals are thus exposed to the highest levels of these contaminants when they are most vulnerable – in the womb and during infancy, when their bodies, brains, nervous systems, and immune systems are in the delicate process of growth
