Special Remarks on
Chronic Effects on Humans
Acute Potential Health Effects:
Special Remarks on other
Skin: Causes irritation and possible burns. It can be absorbed through the skin with symptoms similar to ingestion.
Toxic Effects on Humans
Harmful if absorbed through skin.
Eyes: Causes irritation with possible burns and eye damage.
Inhalation: Can cause respiratory tract (nose, throat, lung) irritation causing sore throat, coughing, tightness in chest,
breathing difficulities, and/or shortness of breath. Pneumonitis may develop.
Ingestion: Toxic. Harmful if swallowed. May cause burining of the mouth and pharynx. Can cause salivation,
metallic taste, abdominal pain, nausea, vomiting, hypermotility, bloody diarrhea. May affect the kidneys
(proteinuria, acute renal failure).
Inhalation/Ingestion: High or repeated exposure can cause Mercury poisoning. Mercury poisoning causes sore gums,
personality changes, tremor/"shakes" (often with shaky handwriting), clumsiness, fatigue, irritability and increased
saliva. Other changes may include serious personality changes memory loss, extreme shyness, weakness, stomatitis,
gingivitis, loss of teeth, gastrointestinal disturbances, metallic taste, poor appetite/anorexia, weight loss, "pins and
needles" (peripheral neuropathy). Exposures can also affect the liver, cause kidney damage, and may cause
decreased visual acuity, and affect peripheral vision (the ability to see to the side). Brain damage can occur,
especially if exposure continues.
Chronic Potential Health Effects
Mercurous Nitrate, Dihydrate
Inhalation/Ingestion: High or repeated exposure can cause Mercury poisoning. See above for symtoms of Mercury
poisoning.
Eye Contact: brown staining in the eye without visual impairment.
Skin: Repeated skin contact can make the skin turn gray. Skin allergy/dermatitis can also occur. If this happens, even
small future exposures can cause rash.
Note: In addition to the effects of exposure to mercury, this product is also a nitrate. The first clinical signs associated
with nitrate poisoning include: Gastroenteritis, abdominal pain, nausea, vomiting(spontaneous vomiting), diarrhea,
metabolic acidosis. Purging and diuresis can be expected. The toxicity of nitrates is due to the in vivo conversion to
nitrites. The primary toxic effects of nitrites include orthostatic hypotension (due to perpheral vasodilation) and
methemoglobinemia (the formation of methemoglobin in the blood which causes deficient oxygenation of the blood
due to decreased available hemoglobin). Other symptoms may include muscular weakness, dizziness, lightheadness,
fatigue, throbbing headache, mental impairment, incoordination, seizures convulsions, bradycardia or tachydardia
(slow or fast heart beat), dysrhythmias, dyspnea. Furthermore, methemoglobinemia due to inadequate oxygenation
of the blood can lead to progressive cyanosis, and coma. Cyanosis is first visible as a bluish discoloration of the
mucous membranes and unpigmented areas of the body. Prolonged or repeated ingestion of large amounts of
nitrates may affect the liver and can cause nausea, vomiting, anorexia/weight loss, methemoglobinemia
(characterized by dizziness, rapid or slow heart beat, irregular breathing, convulsions), and possible coma and death.
