What heavy metals in the body?

Heavy metals: Elements with physical properties such as metals, semi-metals, etc., with a relatively high density of more than five grams per cm3, sometimes called toxic metals. These elements include Hg mercury, Zn outsiders, Pb lead, cadmium Cd, chromium Cr...... etc. They are elements resulting from certain human activities, soil erosion, and salts crumble in water, eruptions, volcanic rocks and industrial wastes.

The toxicity of these heavy elements has been documented throughout history. Greek and Roman doctors diagnosed severe lead poisoning long before toxicology became a stable flag. Exposure to heavy metals has been linked to underdevelopment, various cancers, kidney damage, etc. Exposure to high levels of mercury and lead has also been linked to autoimmune growth to the growth of joint and kidney diseases, such as rheumatoid arthritis, central nervous system diseases, and periodic system diseases.

 Heavy elements in terms of their hazard are divided into three groups:

Group I (non-dangerous elements), group II (toxic elements but not slightly melted or melted), and group III (highly toxic elements).

 From heavy metals damage to humans, agricultural crops and fruit contaminated with heavy metals consist of the risk of sources of such dangerous and toxic minerals entering the human body. This may cause confusion and confusion in man's knowledge of it and avoiding it because of his ignorance of its source.

The significant and rapid development of technology and progress in the field of industry has been accompanied by many problems, especially those related to the environment and human health, including the negative environmental impact of certain heavy metals on human beings, especially children. Chemical industrial pollutants have recently increased.   

Toxicity of heavy metals and symptoms of their increase in the body 

 The human body can absorb heavy metal after exposure to air, soil and water, affecting the body negatively and requiring immediate attention. Untreated and advanced heavy metals poisoning can lead to death, which does not mean that the process is not gradual as it can be identified by some symptoms as these symptoms depend on the type of metal to which the child is exposed as well as the length of time and quantity, of which these symptoms are ((insomnia, diarrhea, abdominal pain, fainting, fatigue, nausea and vomiting, breathing problems, mood disorders, headaches, rashes...... and others)). Although there is ample evidence of the effects of heavy elements on health, exposure to them remains the same as it may increase in the absence of concerted policy action. Arsenic, chromium compounds and copper are a common element in wood preservation materials, and mercury is widely used in gold extraction from its mines in many parts of America. There is no doubt that lead is still widely used as a gasoline additive. Depending on the poisoning of these heavy metals, there are many starting to use special drugs that dispose of these minerals. This process is called DMSA (extraction therapy), that is, when you enter the body you stick to the minerals and take them out through urine.

The impact of lead on children's health

The main sources of lead exposure to humans are: the use of lead-based paint, the use of lead-based gasoline, as well as industrial sources such as lead mining and smelting, as well as metal seams in preserved food cans, ceramic refinement and battery and cosmetic materials.

There are numerous studies that have shown that exposure to lead can significantly reduce children's IQ,Lead is also considered to be one of the most heavy elements affecting human health in general and children's health in particular. The oldest professional toxins contaminated by air are likely to date back at least 8,000 years as lead smelting ovens first began operating.

Children's bodies absorb lead more strongly than an adult's body and are symptomatic of increased lead in children (learning difficulty, behavioral and aggressive problems, intellectual disability, personality change, slowdown in Speed of neural communication).

A source of concern for children's health is children's exposure to lead and organic pollutants. Although there is growing evidence that many developed countries have reduced human exposure to health risks from toxic chemicals such as lead, mercury, cadmium and PCBs, there is still a significant need to address these problems in other parts of the world.

Heavy metals and their relationship to autism in children

The topic of heavy metals is one of the topics that has been much talked about in the field of autism spectrum disorder. In this regard, a study measured the proportion of heavy metals in the blood of eighteen children with autism spectrum disorder and found that sixteen of them had blood heavy metals that were too high for an adult to bear. This study was likely caused by contamination of the environment with these heavy metals and their entry into the body by inhalation, oral or other means and the child's inability to dispose of them after entering the body. Because of the weakness of this detox process, it will be present in large quantities in the blood and can also enter the brain through a diaphragm that will be incomplete in children. In addition, the entry of these minerals into the brain causes damage to brain cells, enzymes and neural receptors that may provoke an autoimmune reaction.

There are ways to treat poisoning with heavy metals, including giving intravenous fluids, glutathione supplements, antioxidants, extraction method, etc., but although this method is important and effective in treating heavy metals poisoning, especially lead, mercury and arsenic, it may cause a shortage of some essential elements in the body in the child. They must therefore be used only in severe cases and under the supervision of a specialist doctor.
