A new study: exposure to lead affects mental health



Her penetration into the body of children leads to psychological problems during their life

Cairo: Dr. Hani Rami Awad

There is no doubt that persistent exposure to heavy metal vapor and various pollutants in the atmosphere leads to many health problems, whether directly affecting people or indirectly affecting the climate, plants and other organisms.
Given the importance of the subject, there are thousands of studies from different perspectives, the latest of which is the American study by researchers at Duke University, which has drawn attention to the many health risks and prolonged exposure of children to an increase in the amount of harmful metals that lead to leadership is the most important so far, that these risks can affect the mental abilities of children in the distant future.

– Leading penetration
The study, published in the January issue of the Journal of the American Psychiatric Association (JAMA), followed 600 babies born in New Zealand between 1972 and 1973. This is the period when the vapors of various gas products contain large amounts of lead. Exposure to gases from lead was measured at the age of 11, followed by a mental and mental health survey and cognitive abilities for these children aged 18, 21, 26, 32 and 38 years.
While measuring blood lead levels, almost all of the children studied had high levels of lead in the blood, and most of them had small, but very serious proportions of psychological problems when they reached adulthood, and then in the Middle Ages later, which means they were more upset and tense and more nervous excitement.
The researchers also found that exposure to increased amounts of lead fumes was associated with increased rates of drug dependence, smoking and alcoholism. They also suffered from depression, schizophrenia, obsessive-compulsive disorder, anxiety, and sometimes even complete psychosis.
The researchers pointed out that the most dangerous thing is the use of lead pipes in providing water for the citizens during the period, which means injury to a large number of children, even those not directly exposed to steam and gases, especially since the influence of lead on children is associated with previous studies and associated with the occurrence Reduced IQ levels of IQ and behavioral changes.
The researchers noted that the risk was previously in the absence of these symptoms only after a long period of up to three decades, causing the producer of petroleum products and various gases to deal with it without serious severity. But now there must be strong control over the amount of lead that must be found in each product and not be allowed at all to exceed these rates.

According to the study, the psychological and mental changes caused by this exposure may have been related to the child until the end of his life. New Zealand in the 1970s was one of the countries with gas-based products such as gasoline. Naturally, continuous efforts to combat environmental pollution, of course, relate to the fetus.
For example, at the start of this study, when the blood was measured in children who had 11 at that time, 94% of their blood contained 5 micrograms per deciliter of blood (mcg-dL) Take steps to perform a variety of different tests and radiation to ensure that they do not affect the body in a detrimental way.
Also, when mental and psychological health studies were repeated for these children and proved to be more susceptible to mental illness and psychosis, an important question that the study attempted to answer is: "Can these children who have become adults in the 40's or 50 the years to be treated now? Unfortunately, there is no cure for these effects over several decades, but the symptoms can be alleviated. The history of exposure to large amounts of lead should be considered in the minds of doctors during the diagnosis of some psychiatric illnesses, Stane helper.
The American Academy of Pediatrics noted that positive changes in the mental and mental health of children from the control of lead relationships are very promising and that the quantities of lead in the blood of children today can not be compared with those that existed in the seventies or eighties of the past century. But the most important role in focusing on the prevention of lead exposure remains the foundation, and governments should be concerned as they deserve, especially since children absorb more lead from adults, either through respiratory tract or through the digestive system, from lead products used such as food or beverage containers.
Governments must be strict not to set up factories near populated areas, as well as to increase awareness of the danger of lead and its impact on the body, and must also write the components of any product used and the percentage of lead in it and may not contain utensils used in food and drink any part, For bullets.
