Mercury toxicity and the dangers of environmental contamination have been thoroughly investigated.
Mercury is easily absorbed into the human and animal system due to its very susceptibility to evaporation. It reaches the body through the respiratory tract, mucous membranes, skin, as well as through the consumption of contaminated water and food. The absorbed mercury circulates in the body, which is not able to be removed and is deposited mainly in the kidneys and liver, causing severe diseases. It also affects the development of diseases of the nervous system.
It is not biodegradable and forms many toxic combinations, both inorganic and organic. In significant quantities it gets into the human body.
The toxic effects of mercury and its compounds depend on the routes of entry into the body, dose and time of exposure. The vapor pressure of mercury at room temperature is so high that the concentration of mercury at 24C in the atmosphere is 18 mg / m3, which exceeds permissible concentrations several hundred times. The greatest hazard of metallic mercury occurs when the vapor is absorbed by the lungs, because metallic mercury is practically not absorbed from the gastrointestinal tract. Some of the absorbed mercury gets into the blood, while the part penetrates the brain. This leads to the impairment of the nervous system, which is manifested by hand shaking, personality disorders, and in severe poisonings inflammation of the gums. These symptoms occurred after chronic exposure to mercury concentrations in the air above 0.1 mg / m3. Absorption of inorganic mercury from the gastrointestinal tract occurs only to a small extent (over a dozen percent), while organic compounds, e.g. methylmercury, are nearly 100%. After absorption, methylmercury through the blood is supplied to all tissues of the body, accumulating in the kidneys, brain and liver. The classic symptoms of methylmercury poisoning are: sensory disorder in the fingers, palms and feet, impaired hearing, vision and personality disorders in the loss of higher feelings. The effects of poisoning are usually irreversible. The effect of this relationship on the fetus is also tragic. The placenta of a pregnant woman is not an appropriate barrier for methylmercury.

Amalgam – is a serious problem
Dr hab. n. med. Anna Zalewska, a member of the PTS, an adjunct in the Department of Conservative Dentistry, Medical University of Bialystok, recalls that dental amalgams are metal alloys in which the so-called elemental mercury (in the form of liquid or steam) makes up to 50 percent. weight of their composition. Research in the United States of America has shown that dental amalgams are mercury-processing plants or gold, next to the mercury mine, one of the most important sources of elemental mercury in the air.
It should be emphasized, however, that elemental mercury itself has little toxicity. Unfortunately, elemental mercury in the air is deposited in water. As a result of the action of bacteria present in the waters (lakes, oceans, rivers) elemental mercury is transformed (methylation process) in the so-called methylmercury, the most toxic chemical form of mercury. In this way, mercury from dental amalgams through aquatic organisms (fish, seafood) returns to the human food chain.
It has been shown that methylmercury interferes with the immune system (Alzheimer’s disease, Parkinson’s disease, Hashimoto’s disease), disintegrates genetic material (carcenogenesis), and also negatively affects the enzyme systems of the human body. Methylmercury also has neurotoxicity, affecting the sense of touch, taste and vision. The discussed mercury compound is five times more toxic to the developing fetus than to an adult, which, as research shows, can lead to fetal malformations and, consequently, to miscarriages.

Amalgam - taken from life
The amalgam fill consists mainly of elemental mercury 50% – toxic substance and silver, copper and tin. Mercury vapor, which is released from seals, penetrates into the body and accumulates in the tissues. The BIO Intelligence Service report to the European Commission presents incriminating evidence of the effects of mercury on health. Norway, Sweden and Denmark have already resigned from dental amalgam in 2008, and Austrian and German dentists do not use it in children, pregnant women and people with kidney problems. Amalgam can cause allergies, increase the risk of neurological diseases, autoimmune diseases, kidney disease, autism and congenital malformations. It has a negative effect on the brain, the central nervous system and the pituitary gland. Mercury poisoning Mercury may cause damage to the brain, kidneys and lungs, and the symptoms include visual, hearing, speech and muscular coordination.
It goes away from the dental amalgam From Wi-Fi, definitely not. Researchers decided to investigate the influence of the electromagnetic field on the stability of amalgam fillings. The results are not comforting.
The local wireless computer network is practically everywhere where a human resides, of course also the one who has teeth with amalgam filling. Who is paying attention to this fact? This was done by Iranian scientists at the Shiraz University of Medical Sciences (Medical Physics and Medical Engineering Department of Medicine).
Twenty-two premolar teeth acquired as part of orthodontic treatment were used for the study. They were divided randomly into two parties.
All teeth were prepared in an identical way, first a space was prepared for filling with dimensions: 3 mm in length, 2 mm in depth and 5 mm in width. Class V cavities were filled with the same amalgam material.
All teeth were placed in artificial saliva (thickness of the layer surrounding 1.5 cm). The exposure time was set to 14 days, because from many analyzes it appears that after the first two weeks after the amalgam was introduced, the mercury emission drops to a constant level.
Exposure to the impact of Wi Fi 2.4 GHz network was also precisely planned (both propagation time and distance between immersed teeth in the artificial saliva, the router and the working computer connected to the wireless network).
The results did not raise any doubts. Statistically, the concentration of mercury in the saliva surrounding the teeth subjected to electromagnetic wave was twice as high as the level observed in the control group, 0.056 ± 0.025 mg / L and 0.026 ± 0.008 mg / L, respectively.
The result of this study correlates with the results of other analyzes defining the influence of the electromagnetic field on amalgam fillings. Previously, this relationship was checked in the case of exposure to radiation generated, among others by magnetic resonance, X-ray apparatus and – which is essential for almost everyone – by a mobile phone. In all cases, a higher concentration of mercury emitted from amalgam fillings was observed in the human body. (source:www.infodent24.pl )
Amalgam separator, what is it and how it works?
This device is used to stop and collect amalgam particles – including particles found in used water. The amalgam separator collects mercury that is “in line” between the pump and sewer. Dental sewage flows through the vacuum line and passes through an amalgam separator, where teeth fragments, amalgam and mercury are separated and collected. Dental practices remove 3.7 tonnes of mercury a year, which goes into the sewer system, which means that they are the most important factor contributing to water pollution. It is recommended that all dentists give amalgam for recycling. This solution is intended to protect the environment against mercury contained in the removed amalgam fillings.
From January 2019, a provision will come into force that requires some dental offices to install an amalgam separator with an ISO 11143 certificate in order to remove mercury from sewage.
The obligation to use separators in some offices imposes on Poland art. 10 para. 4 of Regulation (EU) 2017/852 of the European Parliament and of the Council of 17 May 2017 on mercury and repealing Regulation (EC) No. 1102/2008.
1. From 1 January 2019, the dental amalgam is used only in the form of an encapsulated dose. Dentists are not allowed to use mercury in non-encapsulated form.
2. From 1 July 2018 dental amalgam may not be used in the treatment of deciduous teeth, in the dental treatment of children under 15 years of age and pregnant or nursing women, except when the dentist deems it absolutely necessary due to special medical needs of the patient.
3.On 1 July 2019, each Member State shall draw up a national plan regarding the measures it intends to implement to gradually reduce the use of dental amalgam. Member States shall make their national plans publicly available on the internet and forward them to the Commission within one month of their adoption.
4. From 1 January 2019, operators of dental offices where dental amalgam is applied or in which dental amalgam fillings are removed or teeth containing such fillings provide their offices with amalgam separators for the purpose of retaining and collecting amalgam particles, including particles found in used water.
Safe removal of fillings with amalgam
Removal of amalgam fillings is dangerous, so it should be done by dentists with extensive experience. If it is wrong, the patient is exposed to high concentrations of mercury. In Poland there are no established procedures for safe removal of such seals. The most important aspect of the procedure – for the patient and for the dentist – is full protection against inhaling the mercury vapor escaping during drilling. During the treatment, high-efficiency suction devices must be used, and so-called cofferdam – a rubber dam for bacteria.
