Intoxications caused by sodium azide are becoming increasingly prevalent in the Netherlands Mutagenesis with sodium azide showed the lethal doses (LD50) of 0. Although industrial exposure is common, fatal ingestion is rare. The elevated sodium azide concentration found in the gastric sample and the amount of gastric content allowed to conclude that sodium azide intake was The elevated sodium azide concentration found in the gastric sample and the amount of gastric content allowed to conclude that sodium azide intake was more than 6g The 2018 versions should certainly have a chapter on lethal inorganic salts, which covers sodium cyanide, azide, and nitrite. The toxicity of this compound is comparable to that of soluble Moreover, a half empty 99% sodium azide flask was found near the corpse. The dose assessment for chemicals is determined by varying the concentration and duration of treatment, the solvent mutagen dose can either be high or low resulting muta- tion frequency [11].

Sodium azide (NaN 3) is a highly reactive, toxic, widely used chemical. Humans can be exposed to azide through three major routes: Pre-soaked seeds of both cultivars were treated with different dosage ranging from 50 to 250 Gy for gamma irradiation, 16 to 80 mM for ethyl methane sulphonate (EMS), and 10 to 100 mM for sodium Sodium azide is soluble in water (40.
