Why are our children more than a dwarf?

A study for the Russian children live in an environment where high concentrations of pollutants are smaller in stature the peers to live in a clean environment. Reuters-sheet for or, after tracking nearly 500 boys during the three years, a group of international researchers to Russia's investigation found that the children had blood concentrations of chlorinated polychlorinated biphenyls (PCB) are lower than the children with low average PCN 3 cm though living in the same geographic region. The height at which both body mass index (BMI-defined correlation between weight and height) are also affected. This number only in the children exposed in the environment have the PCB also lower your friends 2 unit.?

"Large slow phenomenon due to the PCB also has the same expression when children infected with dioxin or other chemicals," Mrs. Jane Burns, a member of the delegation, from the school of public health Harvard University commented. She said the boys in an infected research this more substances than the General U.s. population because they are on the side of the chemical factory, arising out dioxin as a byproduct. The PCB has previously been used in a lot of households, from the eating tools (utensils), lighting to insulation and household chemicals (cosmetics, pesticides, cockroach detergent). In the 1970s, they were banned because of the potential hazard to the health of those still exist everywhere as they accrue quite a lot in the environment, in fat, fat cattle, poultry.

Research shows that there is relationship between PCB concentrations with high rates of cancer, diabetes typ 2 and other diseases. Taiwanese children from fetalcells in the ễm PCB from cooking oil contaminated with impurities also dwarf than friends the same age.

Dioxins are toxins formed when organic matter burned in forest fires as well as from waste incinerator plants. From the air it is trees, land and water to absorb, go into the food chain (vegetables, fish, meat). The dioxin exposure also leads to cancer and alter the male/female ratio at birth (more women, at least).

Continue to study the effects of the exposure to PCB and dioxin to the development, Burns and his colleagues took blood samples of 499 boys 8 and 9 years old in the region of Chapae, considered heavy pollution. She said the PCB and dioxin concentrations of them far beyond the respective concentrations of American children. The nosocomial exposure to PCB before birth involves weighing of infants. Along with differences in height and weighed in the age before puberty (prepubescent), the author also said the children were contaminated with PCB per year lower in children not exposed 0.3 cm in 3 years. Yet clearly the PCB and dioxin how to impact the great process of the child. Burns said in an interview Board: "We also assume a mechanism but not sure. That's dioxins interfere with genes that regulate the development, while the PCB do pre-screening disorders of thyroid hocmôn dominated the maturation ".
