Symptoms & Health Effects

Exposure to toxic heavy metals such as mercury, lead, cadmium and arsenic can affect multiple organs and biological systems, sometimes producing symptoms that are difficult to recognise or associate with environmental exposure. Depending on the metal, dose and duration of exposure, health effects may include fatigue, neurological disturbances, memory and concentration difficulties, digestive problems, hormonal disruption, and impaired kidney or cardiovascular function.

In this section, we explore the scientific evidence linking heavy metal exposure to various symptoms, chronic health conditions and disturbances in essential metabolic pathways. Discover how toxic metals interact with the nervous, immune, endocrine and other body systems, and why understanding their potential health effects is an important step towards prevention, early recognition and better long-term health.
