ThecadmiumIt is a heavy metal, described as toxic to humans. A new study reveals that in common environments, people with a higher level of cadmium in the blood and urine are registering deterioration and cellular aging, predisposed to cardiovascular and kidney diseases or others similar to those of the elderly.
The document describes that its evil lies in the fact that it causes cells to prematurely age at the level of DNA stabilizers. It would be transforming people into older, more tired and sicker beings, at lower levels of cadmium than thought.
The toxicity of cadmium, a silvery metal corresponding to element 48 of the periodic table, is affecting through the air and contaminated food, in addition to tobacco.
"The study is the largest to examine the links between cadmium and cell aging in people and suggests that heavy metal exposure may play a role in chronic diseases, such asheart disease and kidney disease"Said Professor Ami Zota, from the Department of Environmental Health at George Washington University in the US, and leader of the study, according to Eniviromental Health, on January 6.
"Our data are consistent with previous evidence that cadmium exposure can cause measurable, deleterious biological health effects. even at levels well below current safety standards used by the environment and professional bodies”Said Professor Zota.
His team studied the telometer pieces of white blood cells, which in medicine are known as markers of aging. They are believed to act as stabilizers for human genes, and therefore stabilizers for the correct cellular function of the body.
They measured the levels of lead and cadmium in the blood and cadmium in the urine, in a national representative sample of American adults from the registry of the National Health and Nutrition Service between 1999 and 2002, and at the same time they observed their DNA and measured what they were like. telometer status, says their study published in the Amercan Journal of Epidemiology on Dec. 10.
A marked relationship between increased cadmium levels and increased damage to telometers was then discovered. This relationship was not observed with levels of lead, which is also a toxic heavy metal.
When exposed to cadmium, telometers were seen to get too short, and then these exposed cells "weaken," said Professor Ami Zota.
Harvard epidemiologist Andrea Baccarelli, who was not involved in the study, explained that cadmium has been associated with inflammation, oxidative stress, and inhibition of DNA repair - all of which could promote telomere shortening noted by the Professor Zota in her study, according to Enviromental Health.
Although cadmium is naturally occurring on Earth, it is produced to makebatteries and sheets of iron and steel. It is also used in the stabilization of some plastics and in the manufacture of pesticides and fertilizers.
Zota tested the blood and urine of more than 6,700 of the people for cadmium. People with the highest cadmium level in their blood had telomeres about 5.5 percent lower than people with the lowest cadmium level.
She did the same with urine concentrations and found the highest group had shorter telomeres about 4.5 percent than the lowest group.
People in the highest blood cadmium group are defined as having levels greater than 0.7 micrograms per liter, whereas the average in the US is that people record approximately 0.3 micrograms per liter of blood, According to the report.
The levels of the study participants corresponded to what is commonly seen in people. "We are looking at environmental exposures at the general population level," Zota said.
The average cadmium levels of the population in which the researchers observed effects of cellular deterioration were approximately 10 times lower that some of the cadmium levels reported as being of concern for theWorld Health Organization (WHO), stressed the teacher.
The danger that Professor Zota warns is that “people are exposed to cadmium throughcontaminated food, tobacco smoke, and air pollution near industrial areas”.
"Cadmium remains in the body for decades," said Josh Edwards, an associate professor of pharmacology at the University of the Midwest, who was not involved in the study. It has a "biological half-life of 30 years or less in the kidneys," according to Environmental Health.
This metal sticks to the ground, so plants and animals accumulate it. In this way, the excrement of contaminated animals, used in food production in agriculture, also has high levels of cadmium and affects them.
Cadmium, among other uses, is in batteries; in that of yellow pigment in paints and glass; for the coating of copper and iron for anticorrosive properties; in alloys with other metals; pipe welding; tobacco from cigars; fossil fuel companies; garbage incineration; Y phosphate fertilizersAccording to the team from México Justo, who denounced the company Petróleos Mexicanos for the use of cadmium in its processes through a video.
The universal principles acquired by the nations are to take care of the environment and not to pollute the air that is breathed, and the food that is consumed.
