New study: Lead effects on mental health



Its penetration into the body of children leads to psychological problems throughout their lives.

Cairo: Dr. Hani Ramzi Awad

There is no doubt that the constant exposure to vapors of heavy metals and various pollutants in the atmosphere leads to many health problems, be it direct effects on people or indirect effects on climate, plants and other organisms.
Given the importance of this issue, there are thousands of studies from different perspectives, the latest of which is a US study conducted by scientists from Duke University, which drew attention to the many health risks and long-term effects on children of increasing amounts of harmful metals, of which lead is the most important in history, it is these risks that can affect children's mental abilities in the distant future.

– Lead Penetration
The study, published in the January issue of the Journal of the American Psychiatric Association (JAMA), found 600 newborns born in New Zealand between 1972 and 1973. This is the period when a pair of different gas products contained a large amount of lead. Lead-based gas exposure was measured at 11 years of age, followed by a survey of the mental and mental health and cognitive abilities of these children at 18, 21, 26, 32, and 38 years old.
When 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 middle age, which meant that they were more concerned and tense. And nervous excitement.
The researchers also found that exposure to elevated lead fumes was associated with an increase in the frequency of drug addiction, smoking, and alcoholism, as well as periods of depression, schizophrenia, obsessive-compulsive disorder, anxiety, and sometimes even complete psychosis.
The researchers noted that the most dangerous thing is to use lead pipes to deliver water to citizens during periods, which means that more children are injured, even those who are not directly exposed to vapor and gas, especially the effect of lead on children is due to previous studies and associated with the occurrence of a decrease in IQ IQ and change in behavior.
The researchers noted that previously there was no risk in the absence of these symptoms only after long periods of up to three decades, which forced the producers of petroleum products and various gases to cope with it without sufficient seriousness. But now there must be strict control over the amount of lead that should be found in each product, and not to exceed these indicators in general.

– life problems
According to a study, the psychological and mental changes caused by this exposure could be associated with a child for the rest of their lives. In New Zealand in the 1970s there was one of the countries with lead-based products such as gasoline. Naturally, the ongoing efforts to combat pollution have certainly borne fruit.
For example, at the beginning of this study, when blood lead was measured in children aged 11 years, 94% of their blood contained 5 µg per deciliter of blood (µg-dl). Take steps to perform a variety of different tests and emissions to ensure that they do not have a harmful effect on the body.
In addition, when repeated examinations of the mental and psychological health of these children were carried out, and it turned out that they were more susceptible to mental illness and psychosis, an important question to try to answer was: “Is it possible to treat these children who have become adults in age 40 to 50 now? ". Unfortunately, for several decades there was no cure for these effects, but the symptoms could only be alleviated. The history of the impact of a large amount of lead should be considered in the minds of doctors in the diagnosis of certain mental diseases, to become an assistant.
The American Academy of Pediatrics indicated that positive changes in the mental and mental health of children, because control over the ratio of lead is very promising, and that the amount of lead in the blood of children today cannot be compared with those that existed in the seventies or eighties of the last century. But the most important role in preventing lead exposure remains the foundation, and governments should be as concerned as they deserve, especially when children absorb more lead in adults through the respiratory tract or the digestive system, from lead products that are used as food containers or beverages. .
Governments should be strict so as not to create factories near residential areas, and to raise awareness of the dangers of lead and its effects on the body, and also record the components of any product used and the proportion of lead in it and should not contain the utensils used in food, and drink in any proportion, From bullets.
