Other Causes
Aside from seafood consumption, there are several other sources of mercury exposure. One significant source is amalgam dental fillings, which can contain up to 50 percent mercury. While many dentists now prefer to use modern materials, some still rely on traditional amalgam fillings. Another surprising source of mercury is certain brands of cosmetics and skincare products, which may use small amounts of mercury as a preservative.
Furthermore, older products like paints, jewelry, and thermometers may also contain mercury. It is important to be cautious when handling or using these items. Additionally, some industries, such as coal plants, emit mercury into the air, which can pose a risk to both employees and individuals living in proximity to these factories.
Soluble Mercury
Mercury exists in various forms, some of which are soluble in water. One of these forms is known as methylmercury, while inorganic mercury compounds also pose similar risks. Methylmercury is released into the environment through natural processes such as volcanic activity, forest fires, or weathering, which convert inorganic mercury into this soluble form. In aquatic systems, microbes play a role in transforming mercury into methylmercury. On the other hand, inorganic mercury compounds are commonly found as salts, such as mercuric chloride and mercurous chloride. These compounds, along with methylmercury, have high solubility, making them easily absorbable by the digestive system. While the salts are more likely to cause damage to the stomach and liver, methylmercury has the potential to harm the brain.
