Description of key information
Exposure-related observations were described in three reports. The normal fatal dose of potassium nitrate for an adult was determined to be between 15 and 35 g, although death has been reported after taking as little as 3.5 g. Cases of methaemoglobinaemia have been noted after an overdose of KNO3 and of bismuth subnitrate. Single oral doses of 25-170 mg potassium nitrate given to humans resulted in a urinary nitrate excretion of 65-70% irrespective of the dose. Excretion was maximal 5 h after ingestion and returned to baseline levels within 18 h.
