Test BackgroundTrace elements can be essential or toxic. Trace element toxicity can occur as a result of occupational exposure, environmental exposure or iatrogenic toxicity. Any organ can be affected: the central nervous system, liver, kidneys, muscles or circulatory system. All elements can be toxic in excess. Those most commonly associated with toxicity include: aluminium, lead, arsenic, cadmium, mercury, thallium, barium, germanium, tellurium, tin, antimony, osmium and uranium. Inorganic and organic compounds of mercury are widely used as antibacterial and antifungal agents in the form of liquids, powders and paints. The kidney is the major target organ for inorganic mercury following absorption, with renal tubular necrosis and glomerulonephritis typically the result.
