How To Prevent And Treat Mercury Poisoning

Mercury poisoning occurs when an individual ingests a toxic level of mercury, a naturally occurring metal found in foods and the environment. Mercury poisoning usually occurs gradually over weeks or months as an individual accumulates more and more of this metal in their body. Individuals of any age can be affected by mercury poisoning, and it is especially dangerous for pregnant women, the elderly, and children. Symptoms of mercury poisoning generally appear slowly and include anxiety, memory problems, depression, irritability, numbness, and tremors. Symptoms can also include vision changes, coordination difficulties, and difficulties with hearing and speech in adults experiencing an acute episode of mercury poisoning. Mercury poisoning can be diagnosed with a clinical examination and blood or urine tests.

The steps outlined below are useful in the prevention and treatment of mercury poisoning.

Avoid Consuming Seafood With Mercury

The consumption of seafood containing mercury is the most common method of mercury poisoning, as all seafood naturally contains at least some mercury. Shark, swordfish, king mackerel, bigeye tuna, and marlin have the highest amounts of mercury. Other types of seafood such as anchovies, catfish, albacore tuna, shrimp, and salmon are considered safe to eat up to two times a week. However, eating these and any other kinds of seafood contributes to mercury accumulation in the body and may pose a health risk. In particular, doctors recommend pregnant women avoid consuming seafood at all stages of pregnancy. Women should also avoid seafood while they are breastfeeding, as mercury is passed to infants through breast milk. Individuals should monitor their consumption of seafood and consider cutting down on the amount they eat. There are many vegetarian and vegan options that can be substituted in place of seafood.

In addition to the risk of mercury poisoning from seafood, the environment also poses a risk of this condition. Individuals can take steps to change their living or working environment to minimize this risk. In the home, it is important to avoid the use of mercury thermometers. These can be safely recycled at dedicated facilities, and digital thermometers are safe substitutes. Some household paints and jewelry may contain mercury, so patients should check this before purchasing these items. Skincare products, especially skin-lightening creams, may contain mercury; patients should always read the label when choosing skin care items. Silver and amalgam dental fillings contain mercury, and patients who have these may wish to speak to their dentist about removing these and replacing them with a safer alternative. Workers who work in coal or gold mines have a higher risk of mercury poisoning and should ensure they take proper precautions to minimize exposure. The air around mines and factories where mercury is released as a by-product of the manufacturing process is considered highly toxic. When purchasing a new home, prospective buyers should check the location of any mines or factories near the area and try to purchase a home as far away from these as possible.
