Scientists from the College of Osteopathic Medicine Edward Via (VCOM) and the Polytechnic University of Virginia recently announced an alarming discovery, according to the Internet publication for girls and women from 14 to 35 years Pannochka. net Quaternary ammonium compounds, which are part of household chemistry, can cause congenital malformations.
While this was confirmed on rodents.
Quaternary ammonium compounds (HOA) are added as disinfectants or preservatives in household chemicals, shampoos, conditioners, and even ophthalmic dosage forms. In low doses are considered safe for the body.
"These chemicals are regularly used at home, in hospitals, in public places, in swimming pools. Most of today's people are exposed to HR daily, "says Anatomy Professor Terry Hrubec of the Virginia Tech Department of Biomedical Sciences and Pathobiology.
Grubek and his collaborators took on the aim of two connections:.
- Benzalkonium chloride (alkylbenzyldimethylammonium chloride).
- Didecyldimethylammonium chloride, DDAC These substances are highly valued in the industry due to their antimicrobial and antistatic properties, as well as a reduction in the surface tension of liquids.
The effects of benzalkonium chloride and DDAC on pregnant female mice and rats resulted in the birth of offspring with neural tube defects. The described congenital malformations are identical to spina bifida and anencephaly (underdevelopment or absence of cerebral hemispheres) in humans.
"Under the influence of quaternary ammonium compounds on females and even males, we observed horrific congenital malformations in offspring. Especially we are concerned about the fact that quaternary ammonium compounds (HR) are dangerous for both parents, "commented Grubek.
Scientists noted that for the manifestation of teratogenic properties of benzalkonium chloride and DDAC do not need prohibitive doses of toxins. It is enough to use authorized cleaning agents in a cage where animals multiply!.
But the most terrible thing is that the increased risk of congenital malformations (neural tube defects) persisted two generations after the impact of HR.
Early experiments in the Grubeck laboratory showed that these chemicals lead to a decrease in fertility in rodents. From the results of further experiments, it follows that quaternary ammonium compounds (QAS) reduce the content of spermatozoa in the seminal fluid and inhibit ovulation in rats.
These are all the causes of infertility, characteristic of modern people!.
"We are asked: do you see the results on mice, and can you transfer them to humans? Yes. The experiments demonstrated that benzalkonium chloride and DDAC disrupt the mechanisms common to the embryonic development of all mammals. Rats and mice are the "gold standard" in similar studies, "the professor assured.
Quaternary ammonium compounds were introduced into household chemistry in the 1950s, when standardization of toxicological studies did not exist at all.
The chemical industry has conducted several of its own studies, but their results have not been published even in the US.
Now, American scientists call on the Environmental Protection Agency to initiate independent epidemiological studies (monitoring real people, consumers of products). This is the only way to determine the likelihood of adverse outcomes, and take action at the highest level.
And while foreign scientists start work, we call readers Medbe. en take care of your own health and avoid unnecessary contacts with HR.
