People who work in these settings are more likely to develop poisoning over time.Įating fish is the most common way people are exposed to methylmercury. It’s also common for children to play on floors, where mercury spills might occur. This is due to their smaller lung capacity. Because the fetus is still growing, it’s more likely to develop neurological effects from mercury.Ĭhildren are more likely to experience mercury exposure through inhaled vapors. This includes: Young ageįetuses and children have a higher risk of mercury exposure.Ī fetus in the womb can be exposed to mercury if the mother eats fish containing mercury.

Chelation treatment with 2,3-dimercaptopropane-1-sulfonate was subsequently initiated and over a period of 8 months his symptoms resolved and his thyroid function test returned to normal. Finally, heavy metal measurements revealed a blood Hg level that was greater than the reference values of 0 to 9 ng/mL. The patient developed hypertension and tachycardia, and was found to have elevated 24-hour vanillylmandelic acid and metanephrines. Thyroid studies also revealed elevated free thyroxine levels in the presence of normal triiodothyronine and thyrotropin. He was eventually admitted to the hospital with altered mental status and was noted to have hyponatremia with serum sodium of 121 mEq/L. ![]() The child was initially managed in the outpatient setting, and the investigation was mainly targeted toward infectious etiology, including Rocky Mountain spotted fever and Lyme disease.
