What gets rid of mercury?
If you have mercury poisoning with a very high level of mercury in your blood, your doctor will probably recommend chelation therapy. This method involves using medications, called chelators, that bind to mercury in your body and help it to exit your system. Chelators can be taken as a pill or injected.
Does mercury go away when fish is cooked?
Trimming skin and fat and cooking method do not reduce mercury exposure. The only way to reduce mercury exposure is to reduce consumption of contaminated fish. Thus, the DSHS recommends eating smaller, younger fish that have had less time to accumulate mercury in their tissues.
Does cooking fish destroy mercury?

How do I know if I have too much mercury?
Symptoms of mercury poisoning. Symptoms of mercury poisoning depend on the form of the mercury that was the source of the exposure. Early symptoms of mercury poisoning can include a metallic taste in the mouth and numbness and tingling in the hands, feet and face.
How can I test myself for mercury?
The most commonly accepted methods of assessing mercury exposure are to test urine or blood. Both tests usually measure levels of total mercury (elemental, inorganic and organic). Elevated mercury in urine usually indicates exposure to an elemental or inorganic source of mercury, such as from a job that uses mercury.
Does mercury leave the body?
Urine and feces are the main pathways of excretion, although a small amount of inhaled mercury can be eliminated in the breath, sweat, and saliva. The excretion of elemental mercury is dose-dependent and biphasic: initially rapid, then followed by slow excretion.
What is the most common way to get mercury poisoning?
