How long does mercury stay in your body?
Asked by anonymous on Nov 05, 2009 in Health Conditions



Does mercury ever leave your body?  If so how long does it take?


Answer

Approximately one half of the mercury absorbed from a single dose will be eliminated within two months, but it can take several months to remove all traces of mercury.  The body gets rid of mercury through the urine and the feces. "Chelation" therapy is used when mercury levels are extremely high.  Factors that determine the severity  of the health effects from mercury exposure include: dose, duration of exposure, age of the person exposed (the fetus is most susceptible), route of exposure (inhalation, ingestion or skin contact), and the health and nutritional status of the person involved.
