The study is the first to link asthma to
hexachlorobenzene exposure during fetal development, and builds on two earlier studies that linked the respiratory disease to polychlorinated biphenyls.
Study: Jandacek, Ronald J., et al. «Effects of yo - yo diet, caloric restriction, and olestra on tissue distribution
of hexachlorobenzene.»
Toxic blasts from the past Beginning in the mid-2000s, scientists observed higher levels of certain POPs,
including hexachlorobenzene and polychlorinated biphenyls (PCBs), at the Norwegian research station.
Hexachlorobenzene and PCBs, the chemicals detected in increasing amounts in Norway and Canada, evaporate more easily than many other POPs, and are harder to dissolve in water.
Higher blood levels of pollutants such as bisphenol A (BPA), polychlorinated biphenyls (PCBs) and
hexachlorobenzene (HCB) have been found in mothers with failed IVF attempts, according to a handful of recent studies.
The same researchers also reported a link between another long - banned pollutant,
hexachlorobenzene (HCB), and implantation failure, in a paper published online in Environmental Health Perspectives in August.
Persistent Organic Pollutants include: aldrin, dieldrin, endrin, chlordane, DDT, heptachlor,
hexachlorobenzene, mirex, toxaphene, PCBs, dioxins, and furans.
The chemicals intentionally produced and currently assigned for elimination under the Stockholm Convention are the pesticides aldrin, chlordane, dieldrin, endrin, heptachlor,
hexachlorobenzene (HCB), mirex and toxaphene, as well as the industrial chemical Polychlorinated Biphenyls (PCBs).
