toxic effect for paralysis sports center, the respiratory center and the surrounding blood vessels; The formation of high iron protein. Acute poisoning of general weakness, headache, dizziness, nausea, vomiting, diarrhea, chest sense of urgency and difficulty breathing; Check to see clear purple purple skin and mucosa. Serious blood pressure to drop, coma and death. Contact workers hands and foot skin damage can occur.

2, toxicology data and environmental behavior

toxicity: through the mouth is a highly toxic. Acute toxicity:

LD5085mg/kg ( Through the mouth) of rats ; 65mg/kg( Rat vein)

dangerous features: inorganic oxidants. And organic matter, a mixture of fuel combustion and explosion, and emit toxic excitant nitrous oxide gas. With ammonium salt, fuel powder or cyanide mixtures will explode. Heat or acid nitrogen oxides can produce poisonous gas. Combustion (

Decomposition) Product: nitrogen oxides.
