Toxins: developmental disorders in children

Brain damage and developmental disorders in children due to toxins

As a result, brain damage and developmental disorders can occur in children who are exposed to neurotoxins for an extended period of time. According to experts, around every sixth child worldwide suffers from a disturbed brain development, which is manifested, among other things, by autism, ADHD, dyslexia or cerebral palsy. Two researchers are now urgently warning that numerous environmental toxins have not yet been adequately tested with regard to the health risks. As nerve toxins, they could cause severe damage to fetuses and children. So far, 214 substances are known that cause brain development disorders in children. But that could only be the tip of the iceberg.

Many toxins have not been tested for possible dangers to the brain development of fetuses and children. Philippe Grandjean from the University of Southern Denmark in Odense and Philip Landrigan from the Mount Sinai Medical Center in New York speak of a "silent pandemic" of brain development disorders, especially in young children should be preserved. In a technical article in the journal "The Lancet Neurology", the two experts named at least twelve substances that have been shown to cause brain damage in children. However, a total of 214 chemicals that have not yet been adequately tested could be found in furniture, clothing and toys cause serious damage to the human brain.

“In 2006, we conducted a systematic investigation and identified five industrial chemicals as developmental neurotoxins: lead, methylmercury, polychlorinated biphenyls, arsenic and toluene. Since 2006, epidemiological studies have documented six additional developmental neurotoxins: manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachlorethylene and polybrominated diphenyl ether, ”the researchers report in the journal. But all of this could only be the tip of the iceberg. "We are very certain that there are still so far undiscovered neurotoxins." The majority of the more than 80,000 industrial chemicals used in the United States have not yet been tested for a potentially harmful effect on fetuses and children.

Thorough tests to protect fetuses and children from nerve agents "The current regulations on chemicals are unfortunately inadequate to protect children whose developing brains are particularly sensitive to toxic environmental chemicals," said Grandjean in a statement from the magazine. "The only way that Reducing contamination with toxins must ensure that existing and new chemicals are tested for neurotoxicity before they go on the market, "emphasizes Landrigan. He demands thorough tests from the manufacturers to prove that the substances used are harmless. "In order to coordinate these measures and accelerate the transfer of scientific results into prevention, we are proposing the urgent establishment of a new international authority," the researchers advise. "Our very great concern is that children worldwide will be exposed to undetected toxic chemicals that Hollowing out intelligence silently, disrupting behavior, preventing future success and damaging societies, hardest in developing countries.
