Understanding Mercury Poisoning: A Comprehensive Overview

Mercury poisoning, a serious health concern, occurs when the body accumulates excessive amounts of this toxic metal. While small quantities of mercury in everyday products and foods may not pose immediate health risks, prolonged exposure or high doses can lead to severe complications. This article delves into the causes, symptoms, and preventive measures associated with mercury toxicity.

The Sources of Mercury Exposure: From Nature to Industry

Mercury is a naturally occurring element, but human activities have significantly increased its presence in the environment. Industrial processes, coal combustion, and waste incineration contribute to the release of mercury into the atmosphere. This toxic metal can then find its way into soil and water systems, eventually entering the food chain.

Common Sources of Mercury Exposure

• Contaminated seafood
• Certain types of jewelry
• Dental amalgams
• Broken fluorescent light bulbs
• Some medical devices (e.g., thermometers)

Among these sources, consuming methylmercury-contaminated seafood is the most common cause of mercury poisoning in humans. Methylmercury, an organic form of mercury, is particularly dangerous due to its ability to accumulate in living organisms.

Recognizing the Symptoms: Early Warning Signs of Mercury Toxicity

Mercury poisoning can manifest in various ways, affecting multiple body systems. The symptoms may develop gradually or appear suddenly, depending on the level and duration of exposure.

Common Symptoms of Mercury Poisoning

• Anxiety and depression
• Irritability and mood swings
• Memory problems
• Numbness in extremities
• Tremors
• Pathological shyness

Can mercury poisoning cause neurological symptoms? Yes, mercury is particularly notorious for its effects on the nervous system. Individuals experiencing sudden onset of these symptoms should seek immediate medical attention, as it could indicate acute mercury toxicity.

Mercury Poisoning in Adults: Advanced Symptoms and Long-term Effects

As mercury accumulates in the body over time, more severe symptoms may emerge in adults. These can significantly impact daily life and overall health.

Advanced Symptoms in Adults

• Hearing and speech difficulties
• Lack of coordination
• Muscle weakness
• Peripheral neuropathy
• Gait disturbances
• Vision changes

Long-term exposure to mercury can lead to permanent damage to vital organs. Are the effects of mercury poisoning reversible? While some symptoms may improve with treatment, severe cases can result in irreversible brain and kidney damage, as well as circulatory failure.

The Vulnerability of Children and Infants to Mercury Exposure

Children and infants are particularly susceptible to the harmful effects of mercury. Exposure during crucial developmental stages can have far-reaching consequences on their health and well-being.

Developmental Impacts of Mercury Poisoning in Young Children

• Cognitive delays

• Learning disabilities

How does mercury affect fetal development? Mercury can cross the placental barrier, potentially causing severe neurological damage to the developing fetus. Pregnant women and nursing mothers should be especially cautious about their mercury exposure, particularly through seafood consumption.

Mercury in Seafood: Navigating the Risks and Benefits

While seafood is an excellent source of nutrients, certain species can contain high levels of mercury. Understanding which fish to consume and in what quantities is crucial for maintaining a healthy diet while minimizing mercury exposure.

Fish Species with High Mercury Levels

• Shark
• Swordfish
• King mackerel
• Tilefish
• Bigeye tuna
• Marlin
• Orange roughy

Why do larger fish tend to have higher mercury levels? Larger predatory fish accumulate more mercury through a process called biomagnification. As they consume smaller mercury-containing fish, the concentration of the toxin in their bodies increases over time.

Low-Mercury Fish Options

• Salmon
• Sardines
• Trout
• Anchovies
• Haddock
• Tilapia
• Catfish

Is it safe to eat any fish during pregnancy? The FDA recommends that pregnant women consume 2-3 servings (4 ounces each) of low-mercury fish per week. This allows them to benefit from the nutritional value of fish while minimizing mercury exposure.

Prevention Strategies: Minimizing Mercury Exposure in Daily Life

While it’s impossible to eliminate all mercury exposure, there are several steps individuals can take to reduce their risk of mercury poisoning.

Practical Tips for Reducing Mercury Exposure

1. Choose low-mercury fish species and limit consumption of high-mercury fish
2. Be cautious when handling broken fluorescent bulbs or old thermometers
3. Opt for mercury-free alternatives in household items and medical devices
4. Ensure proper disposal of mercury-containing products
5. Stay informed about local fish advisories and water quality reports

How can industries contribute to reducing mercury pollution? Industrial sectors can implement cleaner technologies, improve waste management practices, and adhere to stricter environmental regulations to minimize mercury releases into the environment.

Treatment Approaches for Mercury Poisoning

When mercury poisoning is suspected or confirmed, prompt medical intervention is crucial. Treatment strategies may vary depending on the severity and type of mercury exposure.

Common Treatment Methods

• Chelation therapy
• Gastric lavage (in cases of acute ingestion)
• Activated charcoal administration
• Supportive care and symptom management
• Removal from the source of exposure

What is chelation therapy and how does it work in treating mercury poisoning? Chelation therapy involves administering drugs that bind to mercury in the body, forming compounds that can be more easily excreted. This process helps to remove the toxic metal from the system, potentially alleviating symptoms and preventing further damage.

The effectiveness of treatment often depends on how quickly the poisoning is identified and addressed. In some cases, particularly with chronic exposure, the focus may be on managing symptoms and preventing further deterioration rather than complete reversal of effects.

The Global Impact of Mercury Pollution: Environmental and Health Concerns

Mercury pollution is not just a localized issue but a global environmental and health concern. The far-reaching effects of mercury contamination highlight the need for international cooperation and stringent regulations.

Key Areas of Concern

• Contamination of marine ecosystems
• Impact on wildlife populations
• Bioaccumulation in the food chain
• Cross-border pollution through atmospheric transport
• Effects on indigenous communities reliant on fish-based diets

How does mercury pollution affect marine ecosystems? Mercury in water bodies can be converted to methylmercury by microorganisms, which then accumulates in fish and other aquatic life. This not only poses risks to marine biodiversity but also to human populations that rely on seafood as a primary food source.

International efforts, such as the Minamata Convention on Mercury, aim to reduce global mercury emissions and protect human health and the environment. These initiatives focus on phasing out mercury use in various products, controlling emissions from industrial processes, and promoting safer alternatives.

Causes, Symptoms, Treatment, and More

Small amounts of mercury present in everyday foods and products may not affect your health. Too much mercury, however, can be poisonous.

Mercury poisoning refers to toxicity from mercury consumption. Mercury is a type of toxic metal that we can come into contact with in a variety of ways. This may include consuming certain types of seafood and wearing certain types of jewelry.

The most common cause of mercury poisoning is from consuming too much methylmercury or organic mercury, which is linked to eating seafood.

Mercury itself is naturally occurring, but the amounts in the environment have been on the rise due to industrialization. The metal can make its way into soil and water, and eventually into animals like fish.

Consuming foods with mercury is a common cause of this type of poisoning. Children and pregnant people are the more vulnerable to the effects of mercury poisoning. You can help prevent toxicity by limiting your exposure to this potentially dangerous metal.

Mercury is most notable for its neurological effects. In general, the Food and Drug Administration (FDA) says that too much mercury may cause:

• anxiety
• depression
• irritability
• memory problems
• numbness of the hands, feet, or mouth
• pathologic shyness
• tremors

More often, mercury poisoning builds up over time, along with its effects.

But, a sudden onset of any of these symptoms could be a sign of acute toxicity. Call a healthcare professional right away if you suspect mercury poisoning.

Mercury poisoning is an emergency

If you suspect you or someone else has sudden mercury poisoning, call the Poison Control Center at 800-222-1222 or your local emergency services.

Mercury poisoning symptoms in adults

Adults with advanced mercury poisoning might experience:

• hearing and speech difficulties
• lack of coordination
• muscle weakness
• nerve loss in hands and face
• trouble walking
• vision changes

Mercury poisoning symptoms in children and infants

Mercury poisoning can also disrupt fetal and early childhood development. Infants and young children who’ve been exposed to high levels of mercury may have delays in:

• cognition
• fine motor skills
• speech and language development
• visual-spatial awareness

People who are pregnant or nursing should avoid eating fish with high levels of mercury. Mercury can be passed to a developing fetus in the womb or to a child through breast milk.

High amounts of mercury can lead to long-term and sometimes permanent neurological changes. The dangers are especially notable in young children who are still developing.

Mercury exposure can lead to developmental problems in the brain, which can also affect physical functions such as motor skills. Some children who are exposed to mercury at a young age may develop learning disabilities, according to the Environmental Defense Fund.

Adults with mercury poisoning may have:

• permanent brain damage
• permanent kidney damage
• circulatory failure

Mercury poisoning from fish and seafood

Methylmercury (organic mercury) poisoning is largely linked to eating seafood, mainly fish. Toxicity from fish has two causes:

• eating certain types of mercury-containing fish
• eating too much fish

Fish get mercury from the water they live in. All types of fish contain some amount of mercury. Larger types of fish can have higher amounts of mercury because they prey on other fish that contain mercury too. The concentration of mercury concentrations in fish and seafood may be 1 to 10 million times that of the concentration in the surrounding water.

Fish with the highest levels of mercury can include:

• sharks
• swordfish
• bigeye tuna
• marlin
• tilefish
• king mackerel
• orange roughy

It’s also possible to develop mercury poisoning from eating too much seafood, even if the varieties have lower levels of mercury.

The FDA states that in small amounts, certain types of fish with lower mercury levels may be okay for adults to eat once or twice per week.

Fish and seafood with the lowest mercury levels can include:

Fish and seafood with moderate levels of mercury can include:

Though these options contain less mercury, you’ll want to take care in how much you eat.

According to the FDA, if you’re pregnant or breastfeeding, you should restrict your consumption to 2 to 3 servings of 4 ounces of fish and seafood with the lowest mercury levels per week, or one 4-ounce serving of fish and seafood with moderate mercury levels per week.

A 2020 study found that, for study participants, eating fish less than one time a week had little effect. However, participants who ate fish two or more times a week had dangerously high levels of fetal mercury exposure.

The FDA also recommends that children ages 11 and under eat 2 servings or less per week of fish or seafood with the lowest mercury levels. Serving sizes by age can vary. These serving sizes include:

• Ages 1 to 3: 1 ounce
• Ages 4 to 7: 2 ounces
• Ages 8 to 10: 3 ounces
• Age 11: 4 ounces

Certain states, territories, and tribes in the US may also have specific advisories about water sources where fish are caught that may be contaminated with mercury. It’s best to be aware of these advisories before consuming fish caught by yourself, your family, or your friends.

Other causes of mercury poisoning can be environmental or from exposure to other forms of this metal. These can include:

• broken thermometers that contain mercury
• dental fillings with amalgam
• certain types of jewelry
• mining for gold and household gold extraction
• certain skin care products that may have been purchased abroad or marketed illegally in the U.S., according to the FDA
• exposure to toxic air in industrialized communities

Mercury poisoning is diagnosed with a physical exam and other tests. These tests may include:

• chest radiograph
• urinalysis
• blood tests, such as serum mercury levels, a complete blood count (CBC) and a metabolic panel

A healthcare professional may ask about your symptoms and when they started. They may also ask you about your dietary choices and other lifestyle habits.

If mercury poisoning is suspected, doctors may request additional blood and urine tests to measure the mercury levels in your body.

When detected early, mercury poisoning can be halted. However, neurological effects from mercury toxicity are often permanent.

Mercury poisoning is an emergency

If you suspect you or someone else has sudden mercury poisoning, call the Poison Control Center at 800-222-1222 or your local emergency services.

Mercury is a heavy metal that’s commonly found in the natural world. Mercury poisoning happens as a result of too much exposure to mercury. You can be exposed to mercury in a number of ways, and it can be extremely dangerous to your health.

Mercury is a toxic metal and has caused several large public health crises throughout the world, including in Japan and Iraq. However, depending on what form it’s in, mercury can be harmful or non-threatening. For example, methyl mercury is quickly absorbed by the gut and takes root in many of your body’s tissues. On the other hand, mercury salts are less soluble and don’t have a noticeable effect.

Mercury can be inhaled, absorbed through the skin or eyes, or ingested. The most common ways you might be exposed to mercury are through: 

Fish. When elemental mercury makes its way into water sources, it’s consumed by small fish. The small fish are eaten by bigger fish, and eventually, the predators at the top of the food chain end up with a lot of mercury in their tissues. Tuna, swordfish, and sharks are examples of fish that tend to be high in mercury.

Dental fillings. Modern-day dental fillings have a low level of mercury that is safe for many people. Nevertheless, there’s still a risk of ingesting harmful elemental mercury vapor.

Work environments. Working at a landfill, with mercury thermometers, or in a workplace with broken fluorescent and low-energy bulbs puts you at higher risk of mercury poisoning.

You probably won’t get mercury poisoning if you’re briefly exposed or if you come into contact with a harmless form of the metal. Some people worry about mercury exposure from vaccines. However, the form of mercury used in vaccines is quickly broken down by the body and doesn’t pose a health risk.

Babies in the womb are more susceptible to mercury exposure. Pregnant people who consume fish and shellfish risk exposing their babies to mercury, which can affect their development. People who are exposed to mercury for extended periods of time may also experience more serious effects of exposure.

Because mercury comes in many different forms — and because of the variety of places in your body where it can settle — there’s a wide range of symptoms you might experience. Symptoms of consistent, low-grade exposure to mercury include:

• Tiredness
• Anxiety
• Depression
• Tingly feelings due to damaged nerves
• Weight loss
• Memory loss
• Concentration issues
• Poor peripheral vision
• Difficulty feeling your hands, feet, and mouth
• Poor coordination
• Low muscle strength
• Mental health issues
• Damaged kidneys
• Difficulty breathing

At its worst, mercury poisoning can result in death. If you believe you’ve had prolonged exposure to mercury and are experiencing any combination of these symptoms, get in touch with your healthcare provider.

It can be difficult to diagnose mercury poisoning. Blood and urine testing are necessary but don’t offer a complete picture of the extent of mercury poisoning. In addition to these tests, your doctor will ask you many questions to try to arrive at a diagnosis. They might include:

• Do you have many vague symptoms that are similar to common signs of mercury poisoning?
• Is there a more likely explanation for these symptoms?
• Do you have a background of high possible exposure to mercury, from multiple dental fillings, a diet high in seafood, or a career that exposed you to mercury?
• Do you have a family history of diseases with links to mercury exposure, like Alzheimer’s disease or Parkinson’s disease?
• Do you have any medical conditions that would make it difficult for your body to fight off mercury and similar heavy metals?

If it’s likely that your symptoms point to mercury poisoning, your doctor may decide to move on with treatment.

Regardless of what kind of mercury you were exposed to, you will probably be treated with chelation therapy. During chelation therapy, compounds that are designed to bind to the mercury are inserted into your bloodstream. As these drugs do their work, your body eliminates the mercury.

Take note of the things in your environment that could expose you to mercury. Then, do what you can to eliminate or minimize your exposure. Talk to your doctor if you have questions about your symptoms or had any recent incidents that resulted in direct exposure to mercury.

Chronic mercury poisoning: concept and causes

What is chronic mercury poisoning?

Chronic mercury poisoning is the effect of mercury compounds on the human body, which occurs for a long time and leads to numerous disorders in the functioning of internal organs.

Mercury is a strong poison that not only serves as a dangerous environmental pollutant, but can also enter the human body through various sources such as mercury lamps, mercury thermometers and other liquids and materials containing mercury.

Chronic intoxication can be caused by prolonged exposure to high concentrations of mercury compounds in air, food and water.

The cause of mercury poisoning may be violations of equipment and technology in the extraction and processing of gold and other metals. This is especially dangerous for the population living in the vicinity of mining sites.

Causes of mercury poisoning

Mercury is a heavy metal that naturally enters the environment. There are several reasons for the occurrence of poisoning with this substance:

• Industrial pollution – use of mercury in sanitary and hygienic purposes, as well as in lamps and thermometers, can lead to its release into air, water and soil;
• Consumption of fish containing high amounts of mercury, and especially its high-fat adipose tissue, may lead to poisoning;
• Misuse of medicines containing mercury can lead to long-term poisoning;
• Equipment containing mercury can lead to poisoning if not properly disposed of.

Mercury poisoning can cause serious health consequences, so it is important to take precautions and seek medical attention immediately if signs of toxicity appear.

Development of chronic mercury poisoning

Chronic mercury poisoning is a serious disease that occurs gradually and can last for a long time. This is due to the accumulation of mercury compounds in the body.

Originally , symptoms of chronic poisoning may be subtle or resolve within a short time. It can be muscle and joint pain, fatigue or irritability.

As mercury continues to accumulate in the body, new symptoms may appear gradually. This may include headaches, indigestion, memory and concentration problems, and vision and hearing loss. In the most severe cases of poisoning, paralysis and convulsions may occur.

Mercury is most dangerous for children and pregnant women, as it can cross the placenta and impair the development of the baby’s brain. Therefore, they are advised not to eat mercury-containing food and contact with objects containing mercury.

Treatment for chronic mercury poisoning may include stopping exposure to mercury, detoxifying the body, and prescribing medications to help reverse the negative effects of the poisoning.

By following these tips, you can reduce your risk of mercury poisoning and keep yourself healthy for years to come.

Treatments for chronic mercury poisoning

Diet

Chronic mercury poisoning requires a special diet. It is recommended to eat more vegetables, fruits, herbs, legumes and nuts. It is important to exclude fried, fatty and spicy foods, as well as fast-digesting carbohydrates, alcohol and caffeine from the diet. It is very important to drink plenty of water to quickly cleanse the body of toxins.

Sorbents

Sorbents are substances that can bind toxins and remove them from the body. In case of chronic mercury poisoning, it is recommended to take sorbents such as activated carbon, polyphepan, polysorb, smecta, etc.

Pharmacotherapy

In case of chronic mercury poisoning, it is necessary to consult a doctor who will prescribe an individual treatment. Typically, drugs are used to relieve symptoms, such as drugs that improve liver and kidney function, anticonvulsants, sedatives, etc.

• Detoxification therapy

Detoxification therapy is a procedure aimed at detoxifying the body. In chronic mercury poisoning, the following procedures can be used: magnetotherapy, ozone therapy, bioresonance therapy, automatic hemotherapy, hemoperfusion, etc.

Phytotherapy

Phytotherapy is a treatment with the help of medicinal plants. In chronic mercury poisoning, plants such as corn stigmas, rose hips, nettles, yarrow, lemon balm, mint, etc. can be used.

Traditional remedies for chronic mercury poisoning

Therapeutic nutrition is one of the traditional treatments for mercury poisoning. It is necessary to exclude from the diet foods containing a large amount of fatty foods, spices and alcohol, as well as increase the consumption of vegetables, fruits and herbs.

The use of herbs and plants will also help in healing. For example, you can use a decoction of licorice root, which helps to remove toxins from the body. It is also recommended to use cleansing herbs, including nettle, mint, St. John’s wort and chamomile.

Mineral water , rich in selenium, copper and zinc, can also help detoxify the body. It is recommended to drink mineral water “Narzan” or “Essentuki” every day.

Mud bath with contrasting water temperatures restores the body’s ability to cleanse itself. Baths are recommended to be taken at least twice a week.

• Honey masks and compresses can also help treat mercury poisoning. To prepare the mask, you need to mix 2 tbsp. spoons of honey with 1 tbsp. spoon of oatmeal and apply on face for 15-20 minutes. Honey compresses are applied to the affected area for 15-20 minutes.
• Aloe juice is known for its anti-inflammatory and antioxidant properties. For the treatment of mercury poisoning, it is recommended to use 1 tbsp. a spoonful of juice three times a day before meals.

Prevention of chronic mercury poisoning

Reduce the risk of exposure to mercury

Mercury is the most toxic element to humans, so the risk of exposure must be reduced. There are several ways to do this:

• Wear personal protective equipment. Always wear gloves, masks and goggles if you are working with mercury or its vapour.
• Dispose of mercury properly. Never dispose of mercury with normal waste. It must be collected and disposed of as it accumulates.
• Replace mercury with safe alternatives. Many products, such as mercury spirit lamps and thermometers, can now be replaced with safer, more environmentally friendly, mercury-free alternatives.

Diet

Diet can make a big difference in reducing the risk of mercury poisoning, here are some recommendations:

• Reduce your intake of fish containing high levels of mercury such as shark, freshwater fish, carp and eel.
• Choose seafood with low levels of mercury. Some countries conduct special studies on seafood to determine the concentration of mercury in them.
• Take nutritional supplements. Magnesium, selenium and zinc, found in some dietary supplements, can help you deal with mercury poisoning.

Regular health checks

Regular health checks can help in the early diagnosis of chronic mercury poisoning. If you suspect mercury poisoning, be sure to see a doctor for proper diagnosis and treatment.

Factors contributing to mercury poisoning

Exposure to mercury can occur under the influence of various factors, both external and internal.

Occupational hazard is the most common cause of chronic mercury poisoning. This is because mercury is used in manufacturing processes, such as in the electronics and glass industries or in the manufacture of amalgam fillings. The risks are also high for workers in the mining and processing industries.

Consumption of fish found in contaminated waters can also cause mercury poisoning. Fish absorb toxic substances from the water and accumulate them in their tissues and muscles. The use of such fish can lead to intoxication.

Other factors that contribute to mercury poisoning are self-medication, smoking, poor hygiene when working with mercury-containing substances, and weak immunity. In the presence of these factors, the risk of chronic mercury poisoning increases significantly.

It is important to understand that mercury poisoning can occur from any contact with a toxic substance. Therefore, it is necessary to strictly observe safety measures when working with mercury-containing substances and avoid eating contaminated food.

Q&A:

What are the symptoms of chronic mercury poisoning?

Symptoms may vary depending on how the person has been exposed to mercury. However, common symptoms include muscle and joint pain, headaches, visual and hearing impairment, depression, and problems with memory and concentration.

How can I be sure I have chronic mercury poisoning?

Of course, the best way is to see a doctor and undergo a medical examination. They can check blood and urine levels of mercury, as well as other tests to help determine if mercury poisoning is present.

How can chronic mercury poisoning be avoided?

There are several ways to prevent exposure to mercury, including: do not use mercury thermometers, use safety precautions when handling mercury products, and use precautions when eating fish that are most susceptible to mercury contamination.

How can you remove mercury from your body?

Eliminating mercury from the body can be a complex process and take a long time. However, some methods, such as detox treatments, can help speed up the process. It is best to consult a doctor for professional advice.

Which types of mercury thermometers are the safest to use?

Mercury-free digital thermometers are the safest to use. If the use of thermometers with mercury is unavoidable, then it is better to choose thermometers equipped with a safe expansion bulb to eliminate the possibility of glass breaking and mercury falling out.

How long can chronic mercury poisoning last and how is it treated?

The duration of chronic mercury poisoning depends on many factors, including the level of exposure and the health of the individual. Treatment usually includes avoiding exposure to mercury, detoxification procedures, managing symptoms, and therapy to support liver, kidney, and cardiovascular health.

Mercury (Hg), (material – hair): to be tested in “HEMOHELP”

Description
Preparation

Test Method: Inductively Coupled Plasma Ion Source Mass Spectrometry (ICP-MS)
Units: µg/L
Test Material: Hair
Daily Requirement: 0.5 mcg
The toxic dose depends on the chemical form in which it enters the body. Metallic mercury (in liquid form) when ingested is generally non-toxic, poorly absorbed in the gastrointestinal tract and almost completely excreted in the feces. WHO lists mercury as one of ten major chemicals or groups of chemicals of significant public health concern.
Sources of trace elements: mercury-containing medicines and preparations, amalgam fillings, mercury-containing ointments or creams, seafood, hazardous industries, pesticides, household items containing mercury (thermometers, fluorescent lamps). In some houses you can find antiques covered with mercury amalgam – gilded boxes, mirrors, figurines.
Physiological role: unclear
Causes of deficiency: –
Main manifestations of deficiency: –
Causes of excess: There are different forms of mercury – elemental (or metallic), inorganic, to which people may be exposed at work, and organic, to which people may be exposed while eating. Accordingly, excessive consumption of seafood.

Main manifestations of excess:
When inhaling air containing mercury vapor in a concentration not exceeding 0. 25 mg/m3, the latter is completely retained in the lungs. In the case of higher concentrations of vapors in the atmosphere, another way of their penetration into the body is possible – through intact skin. Depending on the amount of mercury and the duration of its intake into the body, the following are possible:

• acute poisoning;
• chronic poisoning;
• micromercurialism.

Factors that determine the severity of mercury exposure:

• type of mercury;
• dose; age;
• duration of exposure;
• route of entry (inhalation, ingestion or dermal).

The main route of exposure is the consumption of contaminated fish and shellfish and the inhalation of elemental mercury in hazardous occupations.

Symptoms of acute mercury vapor poisoning appear within a few hours after the onset of poisoning – general weakness, lack of appetite, headache, pain when swallowing, metallic taste in the mouth, salivation, swelling and bleeding of the gums, nausea and vomiting; as a rule, there are pains in the abdomen, mucous diarrhea (sometimes with blood). Often there is inflammation of the upper respiratory tract, chest pain, cough, shortness of breath, and sometimes chills. Body temperature sometimes rises to 38-40 °. In the urine – significant amounts of mercury. In severe cases, death is possible within a few days.

Chronic poisoning occurs during relatively long work – for several months, and sometimes several years in rooms whose air contains mercury vapor in quantities slightly exceeding the sanitary norm. The central nervous system is affected. Depending on the type of nervous system, the first signs may be different: increased fatigue, drowsiness, general weakness, headaches, dizziness, apathy, as well as emotional instability, memory loss, attention. Gradually, trembling, which increases with excitement (“mercury tremor”), first of the fingers, then the eyelids, lips, in severe cases, the legs and the whole body, develops. Of great importance for the diagnosis of mercury poisoning is a decrease in skin sensitivity, taste sensations and acuity of smell. There is also increased sweating, frequent urge to urinate, sometimes some enlargement of the thyroid gland, slowing or increased heart rate, lowering blood pressure.

Chronic poisoning causes a predisposition to tuberculosis, atherosclerotic events, liver and gallbladder damage, and hypertension. In women, the menstrual cycle is disturbed, the percentage of miscarriages and premature births, mastopathy increases, pregnancy is more difficult, the children born are often unviable or very weak. The consequences of chronic poisoning may appear several years after the cessation of contact with mercury.

Micromercurialism – chronic poisoning occurs when a person is exposed to negligible concentrations of mercury vapor for 5-10 years. Long before the appearance of the first clinical signs of micromercurialism, there are sharp shifts in the threshold sensitivity to the smell of various substances, which can be detected using special tests. The grounds for testing are fatigue, decreased performance, increased excitability, irritability, headaches, memory loss. Lack of contact with mercury cannot be an argument against suspicion of mercury poisoning, since micromercurialism sometimes occurs under the most unexpected circumstances – the diffusion of mercury vapor from neighboring rooms can play a role, a mercury thermometer broken even a very long time ago if the mercury was not carefully removed. More characteristic signs, which do not appear immediately, however, are small and frequent tremor of the fingers of outstretched hands, bleeding gums, catarrhal phenomena of the upper respiratory tract, the urge to urinate frequently, in women, in addition, menstrual irregularities. If the impact of mercury vapor on the body continues, micromercurialism turns into chronic mercury poisoning with all the symptoms characteristic of it.

Indications for use:

• diagnosis of acute and chronic poisoning;
• survey of employees at enterprises with harmful working conditions;
• diagnostics if there is a suspicion of an imbalance in providing the body with microelements.
