    Toxicity to Animals        Acute oral toxicity (LD50): 49.3 mg/kg [Mouse].    
    Acute dermal toxicity (LD50): 2330 mg/kg [Rat].
    Chronic Effects on Humans May cause damage to the following organs: kidneys, the nervous system, gastrointestinal tract, skin, central nervous
    system (CNS).
    Very hazardous in case of skin contact (irritant), of ingestion.
    Other Toxic Effects on
    Humans        Hazardous in case of inhalation.    
    Slightly hazardous in case of skin contact (permeator).

    Special Remarks on
    Toxicity to Animals
    May cause adverse reproductive effects and birth defects (teratogenic)
    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.
