Influence Of Chemical Substance In Pregnant Women

Various kinds of toxins that provide harm to the fetus during development. A study in 2011 found that almost all US pregnant women carry multiple chemicals, including some that have been banned since the 1970s on their bodies. The researchers detected polyplorinated biphenyls, organochlorine pesticides, perfluorphic compounds, phenols, polyhydrobathic diphenyl ethers, phthalates, polycyclic aromatic hydrocarbons, PBDE perchlorate, compounds used as fire extinguishers, and dichloro diphenyl trichloroethane (DDT), a pesticide banned in the US in 1972 , In the body of 99 to 100 percent of pregnant women tested. Bisphenol A (BPA) is found in 96 percent of women surveyed. Some similarly concentrated chemicals are associated with negative effects in children from other studies and it is thought that exposure to these chemicals can have a greater effect than exposure to just one substance.

Alcohol digestion during pregnancy can cause fetal alcohol syndrome, a permanent and sometimes dangerous birth distress syndrome. Studies have shown that moderate to moderate drinking during pregnancy does not have a significant effect on the fetus, but to be completely safe pregnant women should not drink alcohol at all during pregnancy.

A number of studies also show that children exposed to secondhand smoke can experience a number of behavioral, neurological, and physical disorders. Elements of mercury and methyl mercury are two forms of mercury that can pose a risk during pregnancy. Methyl mercury, a kind of pollutant of seafood and freshwater fish, is known to produce dangerous nervous system disorders, especially during brain development. Eating fish is a major source of mercury exposure in humans and some fish may contain enough mercury to harm the developing fetal nervous system, sometimes leading to learning disabilities. Mercury is present in many species of fish, but is most common in large fish. The Food and Drug Administration and the US Environmental Protection Agency advise pregnant women not to eat swordfish, sharks, king mackerel and tile fish, and limit the consumption of albacore tuna to 6 ounces or less in a week.

 

The Center for Environmental Health reported a study showing that exposure to air pollution during pregnancy is associated with poor births such as low birth weight, premature infants, and heart malformations. Exposed baby blood arc showed DNA damage associated with cancer. Further studies show delayed progression at age three, low IQ test scores, and increased behavioral problems at age six and eight.

According to the US Centers for Disease Control, the developing fetal nervous system is vulnerable to lead poison. A neurotoxin is observed in a child of a woman who is exposed due to the ability of lead to cross the placental obstruction and causes the fetal nerve to record. The particular problem of pregnant women is the accumulation of lead in bone released into the blood during pregnancy. Several studies provide evidence that exposure to small pregnant women in lead can even result in intellectual and behavioral disorders in children.

A 2006 study found that children prenatally exposed to chlorpyrific insecticides had poor motor and mental development at age three and a higher risk of behavior problems. A 2007 study using a mouse model showed that exposure to polycyclic aromatic hydrocarbons at birth and breastfeeding reduced the number of eggs in the womb of girls who were born to two-thirds. The 2009 study of pregnant women exposed to tetrachloroethylene in drinking water increases the risk of oral and neural tube interference in their children. A 2009 study found that prenatal exposure to phthalates, a chemical compound used for plastics in many types of personal care products, toys, and medical devices, may be an environmental risk factor for low birth weight in children. The 2010 study found that prenatal exposure to fire extinguishing compounds called diphenyl ether polybrominate is associated with adverse neural developmental effects in young children.
