Heavy Metals

Aluminum (Al) is a harmful heavy metal that can pose health risks to the human body. Exposure to excessive levels of aluminum, often through diet or environmental sources, has been linked to neurotoxicity and may be associated with conditions such as Alzheimer’s disease. Monitoring and reducing aluminum exposure is important for supporting overall health and well-being.

Arsenic is a naturally occurring element that can be highly toxic to humans. Found in soil, water, and certain industrial materials, it disrupts normal cellular processes and is classified as a carcinogen. Even at low levels, arsenic exposure can pose significant health risks, affecting multiple organs and systems.

Cadmium (Cd) is a toxic heavy metal with no beneficial function in the human body. Long-term exposure to cadmium can lead to serious health issues, including kidney damage, weakened bones, and an increased risk of cancer. Since cadmium accumulates in the body over time, even low-level exposure is a concern for long-term health.

Cobalt is an essential trace mineral found as part of vitamin B12, which is vital for nerve function, red blood cell formation, and DNA synthesis. It is needed in very small amounts, and a deficiency can cause symptoms similar to those of vitamin B12 deficiency. While essential for health, excessive exposure to cobalt can be harmful, potentially affecting the heart, lungs, and thyroid.

Lead is a toxic heavy metal with no beneficial function in the human body. Exposure to lead can cause serious health issues, particularly affecting the nervous system. Even low levels of lead can impact multiple body systems, with children being especially vulnerable to developmental delays and cognitive impairments.

Mercury is a naturally occurring heavy metal found in certain products such as thermometers and dental fillings. While low exposure is generally harmless, excessive levels can be toxic, affecting the nervous, digestive, and immune systems. High mercury exposure may cause symptoms like tremors, sleep disturbances, and cognitive impairment, and it poses significant environmental risks, particularly through water contamination.

Nickel (Ni) is a naturally occurring metal and a widely used industrial element. In trace amounts, it is generally harmless, but excessive exposure can cause health issues such as skin irritation, allergic dermatitis, and respiratory problems. Nickel is also classified as a potential carcinogen, with higher risks observed in occupational settings where exposure levels are elevated.

Thallium (Tl) is a heavy metal that presents significant health risks when exposed to it. It can lead to symptoms such as hair loss, nerve damage, and digestive problems. Common sources of thallium exposure include contaminated water, certain industrial processes, and its historical use in rat poison. Although its presence in consumer products has decreased, thallium still poses a hazard in industrial environments. While exposure to thallium is rare, it requires immediate medical attention to minimize health complications.
