Methylmercury Poisoning: What You Need To Know
Methylmercury poisoning, also known as poisoning caused by mercury, is a type of intoxication that occurs when large quantities of methylmercury enter the body through ingestion, inhalation or dermal absorption. It can cause a range of symptoms, including kidney and neurological damage. It is particularly dangerous for children and pregnant women, as it can have a long-term impact on the developing fetus, leading to physical and mental disabilities.
What Is Methylmercury?
Methylmercury is an organic form of mercury – a chemical element that is naturally present in the environment, but which can become a pollutant when released into the air, water or soil due to human activity. It is created when bacteria in the environment convert inorganic mercury to organic mercury, such as methylmercury. Once it has been created, methylmercury accumulates in the cells of fish, which are then eaten by humans.
How Is Methylmercury Poisoning Diagnosed?
Methylmercury poisoning is diagnosed by looking at a history of exposure to the toxin, combined with physical and neurological symptoms. A doctor may also order lab tests such as a urine or blood test to check for the presence of mercury in the body. Immediate treatment for severe cases of methylmercury poisoning may include chelation therapy, a procedure in which chemicals are used to bind to the mercury in the body and remove it.
Types Of Methylmercury Poisoning
Methylmercury poisoning can occur in two ways: acute and chronic. Acute poisoning happens when a large amount of methylmercury is consumed in a short period of time. Chronic poisoning occurs when methylmercury is consumed over a long period of time, allowing the toxin to build up in the body.
Risks of Methylmercury Poisoning
The risks of methylmercury poisoning from eating fish that contain large amounts of methylmercury include:
- Damage to the nervous system, including problems with coordination, speech and vision.
- Kidney damage and failure.
- Impaired development in unborn children.
- Impaired hearing and motor skills in children.
Why Is Methylmercury Poisoning Dangerous?
Methylmercury poisoning is particularly dangerous for pregnant women or children because it can cause long-term developmental problems in the fetus or in young children. It causes damage to the nervous system, which can lead to learning difficulties, speech problems, hearing loss and vision problems. In severe cases, it can even lead to death.
When Should You Be Concerned about Methylmercury Poisoning?
You should be aware of methylmercury poisoning if you consume large amounts of fish that may contain high levels of the toxin. It is important to be aware of the types of fish that are considered high in mercury, such as tuna, mackerel, marlin and shark. It is also important to limit your consumption of fish during pregnancy and to avoid giving children fish that are considered high in mercury.
