​Mercury toxicity refers to the harmful effects caused by the accumulation of mercury in the body. Mercury is a naturally occurring heavy metal that exists in various forms, with the most common being elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. Each form has its own toxicity profile and potential health risks.

When mercury enters the body, it can disrupt normal physiological processes and have detrimental effects on multiple organ systems. It has a particular affinity for the central nervous system, where it can interfere with neurological functions and impair cognitive abilities. Mercury toxicity can also affect the cardiovascular, immune, endocrine, and renal systems, leading to a range of health problems.

Mercury exposure can occur through various sources, both environmental and man-made. Understanding these sources is crucial in recognizing potential avenues for exposure and taking steps to minimize risk. Here are some common sources of mercury exposure:

• Environmental Sources: Mercury occurs naturally in the environment and can be released into the air, water, and soil through natural processes or human activities such as industrial emissions and waste incineration. Once in the environment, it can bioaccumulate in fish and seafood, making them a significant source of exposure.​
• Dental Amalgams: Dental amalgams, commonly used to fill cavities, contain a mixture of metals including elemental mercury. While the American Dental Association asserts that dental amalgams are safe, concerns have been raised about the release of small amounts of mercury vapor over time, especially during chewing and teeth grinding.
• Contaminated Seafood: Certain species of fish and shellfish, particularly those high on the food chain, can accumulate mercury in their tissues. This is primarily due to the bioaccumulation of mercury through the food they consume. Regular consumption of contaminated seafood can lead to significant mercury exposure.
• Occupational Hazards: Occupations involving industrial processes, such as mining, manufacturing, and chemical production, may expose workers to higher levels of mercury. Industrial accidents or improper handling of mercury-containing materials can result in acute mercury poisoning.
• Consumer Products: Some consumer products, such as older thermometers, barometers, certain cosmetics, and skin-lightening creams, may contain mercury. Accidental breakage or improper disposal of these items can lead to exposure.

​It is important to note that the risk of mercury toxicity varies depending on the concentration and form of mercury, duration of exposure, individual susceptibility, and other factors. By understanding the sources of mercury exposure, individuals can make informed choices to minimize exposure and protect their health.

Mercury toxicity can present with a wide range of symptoms, which can vary depending on the individual, duration of exposure, and levels of mercury accumulation. Functional medicine practitioners pay close attention to these common symptoms and signs when assessing for mercury toxicity:

• Neurological Symptoms: Mercury toxicity can manifest as cognitive difficulties, memory problems, brain fog, poor concentration, mood swings, anxiety, depression, irritability, tremors, and coordination issues.
