A quarter of the modern women poisoned by toxins

Scientists at Brown University in the U.S. carried out a study and found that the blood of almost 23% of American women of childbearing age, a dangerous level three hazardous substances: lead, mercury and PCBs (polychlorinated biphenyls).

In this case, all women aged 16 to 49 years, with the exception of 17.3%, a dangerous level of at least one of these toxic substances, which not only affect women's health, but also transmitted to children — through the placenta and breast milk.

Lead, mercury and PCBs are widespread and are very stable in the environment. They can harm the fetus and the baby's in the infant stage of brain development. At the same time, scientists are still poorly represented, as these three materials in the same effects on human health — usually research is one of the three pollutants.

As it turned out, the majority (55.8%) of the modern women of childbearing age, an increased level of two or three toxic substances. These data were collected in the U.S. between 1999 and 2004 on the basis of blood tests in 3173 women aged 16 to 49 years. Because the study was conducted as part of a larger project center NHANES, were found and the specific risk factors associated with an increased content of toxins.

The most significant risk factor was age naturally: the higher, the higher the level of toxins in the blood, such as women aged 40 to 49 years, the risk was 30 times greater than for women aged 16 to 19 years. This is due not only to the accumulation of toxins, but also to the fact that the first group of women born in the 1950s and 1960s, that is before the tightening of environmental legislation.

They also found that the risk of high levels of toxins associated with the consumption of fish and alcohol abuse. Thus, women who ate fish more than once a week for 30 days, the risk of high toxin content grew by 4.5 times. Even at the level of toxins silnopyuschih women was lower than that of those who like fish.

Fish, especially predatory, such as swordfish or tuna, for life accumulates high levels of mercury and PCBs. However, alcohol is not so simple — it is not entirely clear why his excessive consumption increases the level of toxins, possibly due to lower efficiency of the toxins from the body.

Worst of all, reducing toxins in women who are breastfeeding. This means that hazardous substances were derived in the baby with breast milk. The study does not attempt to accurately assess the effects of toxins on the body of three women and their children. Clearly, however, lead, mercury and PCBs are not conducive to good health.
