Mercury Toxicity

Mercury is a highly toxic heavy metal that can affect the nervous system, kidneys, immune function and other biological processes. Exposure may occur through contaminated fish and seafood, mercury vapour released from certain industrial activities, occupational environments, and other environmental sources. Mercury exists in several chemical forms, including elemental, inorganic and organic mercury, each with different pathways of absorption, distribution and toxicity. Of particular concern is methylmercury, which can accumulate in fish and pose significant risks to the developing brain and nervous system.

In this section, we explore the sources of mercury exposure, how different forms of mercury enter and affect the body, and their potential effects on cellular function, antioxidant defences, enzymes and essential metabolic pathways. Discover the signs and symptoms of mercury toxicity, its possible neurological and systemic health consequences, the role of appropriate blood, urine and hair testing, and practical, science-based strategies to identify exposure risks, reduce unnecessary exposure and protect long-term health.
