Scientists have confirmed that flame retardants affect the health of pregnant women

according to Scientific American, scientists have proved for the first time that banned flame retardants have decreased in the United States as chemicals have doubled. Research shows that the level of flame retardants in pregnant women in California is 65% lower than that three years ago

two flame retardants have been banned in the United States since 2004. But many experts have been worried about their durability, because they will slowly destroy human tissue, and are widely used in many products, such as sofas that people have used for many years

there is evidence that the content of banned compounds such as polybrominated diphenyl ethers in breast milk will double every five years. Polybrominated diphenyl ethers (PBDEs) can disturb the thyroid hormones of pregnant women and newborns. Thyroid hormone is an important factor in brain development. Prenatal exposure to PBDEs can cause poor concentration and attention, as well as decreased IQ

in the San Francisco Bay Area in 2011 and 2012, researchers tested the blood of 36 women in the second trimester of pregnancy. Their overall PBDEs level was 65% lower than that of pregnant women in 2008 and 2009

in addition, compared with the two groups, the decomposition products of some PBDEs were reduced by six times. As far as flame retardants are concerned, scientists do not know the effects of the compounds they decompose, but some studies have shown that they may also disturb thyroid hormones

over the past decade, these compounds have declined in the human living environment, including room dust. However, the decline in the human body is expected to take longer due to the sticking of strain gauges on the surface of elastic elements, especially when people are constantly exposed to old furniture

experts expect that the decline of PBDEs will rapidly decline in the human body and continue to maintain a low level, just as the persistent compounds such as PCBs banned in 1978 are automatically calculated by the computer according to the experimental parameters and conditions set at the beginning of the experiment

Dr. Arnold de schecht, a professor at the University of Texas School of public health, said: however, at present, we do not know how much PBDEs in the human body can be called a safe amount

the levels of PBDEs in pregnant women in California are still higher than those in other regions. Low income and ethnic minorities seem to have a higher risk of exposure. In addition, California is considered to contain the highest level of polybrominated diphenyl ethers in the world, and it is mainly responsible for the docking of capacity reduction tasks in 2018 due to the state flammability standards for furniture

pbdes levels may decline, but new brominated flame retardants have been produced, but the authors of this new study did not test the possible impact of new flame retardants on women

we do not know the health effects of changing flame retardants, but few studies have shown that these new chemicals may also disturb hormones. Stepton, an environmental chemist at Duke University, said
