Mercury (Hg)

A Holistic Approach to Detox by Brisbane Naturopaths

Mercury, a naturally occurring heavy metal, has been a significant environmental concern for decades due to its toxicity and widespread distribution. While it occurs in low concentrations in the Earth’s crust, human activities have significantly increased the amount of mercury released into the environment, posing a threat to human health and ecosystems.

Sources of Mercury Exposure

Mercury can enter the environment through various sources, including:

• Industrial Processes: The mining, smelting, and refining of metals like gold, silver, and zinc can release mercury as a byproduct.
• Fossil Fuel Combustion: Burning coal, oil, and natural gas releases mercury into the atmosphere, contributing to air pollution.
• Waste Disposal: Improper disposal of mercury-containing products, such as batteries, fluorescent lights, and thermometers, can lead to contamination of soil and water.
• Medical Waste: Mercury was once used in dental amalgam fillings and certain medical instruments, and improper disposal of these materials can release mercury into the environment.

The Dangers of Mercury Exposure

Exposure to mercury can occur through inhalation, ingestion, or skin absorption. Once in the body, mercury can accumulate in various organs, including the brain, kidneys, and liver, leading to serious health problems. Some of the potential health effects associated with mercury exposure include:

• Nervous System Damage: Mercury can impair cognitive function, memory, and coordination, particularly in developing fetuses and young children.
• Kidney Problems: Mercury can damage the kidneys, leading to kidney failure in severe cases.
• Cardiovascular Disease: Exposure to mercury has been linked to an increased risk of heart disease and stroke.
• Immune System Dysfunction: Mercury can weaken the immune system, making individuals more susceptible to infections and diseases.

While industrial and environmental sources contribute significantly to mercury exposure, consuming contaminated food can also pose a risk. Certain types of fish, in particular, can accumulate high levels of mercury due to their position in the food chain.

Fish with High Mercury Content:

• Large, predatory fish: These fish, such as swordfish, shark, king mackerel, tilefish, and marlin, tend to have higher mercury levels due to their consumption of smaller fish that may contain mercury.
• Tuna: While most tuna species are safe to eat in moderation, some, like bigeye and albacore tuna, can have higher mercury levels.
• Shellfish: Some shellfish, including oysters, clams, and crabs, can accumulate mercury from contaminated waters.

Safe Fish Choices:

• Low-mercury fish: Smaller, low-mercury fish, such as salmon, tilapia, cod, shrimp, and pollock, are generally considered safe to eat in moderation.
• Variety is key: Consuming a variety of fish can help reduce your exposure to mercury.

Tips for Reducing Mercury Exposure:

• Check fish advisories: Follow local fish consumption advisories to stay informed about mercury levels in fish from your area.
• Limit consumption of high-mercury fish: If you consume fish from the higher-mercury category, limit your intake to no more than once a week.
• Choose low-mercury alternatives: Opt for low-mercury fish or seafood alternatives like shellfish.
• Prepare fish properly: Cooking fish can help reduce mercury levels to some extent.
