The acute toxicity of osmium tetroxide is high, and it is a severe irritant of the eyes and respiratory tract. The compound embodies noteworthy because its more employments, despite the rarity of osmium. It also has a number of interesting properties, one being that the solid is volatile. Exposure to osmium tetroxide vapor dismiss legal injury the cornea of the eye. Irritation is generally the initial symptom of exposure to low concentrations of osmium tetroxide vapor, and lacrimation, a granular intuitive feeling in the eyes, and the appearance of calls up close to brightnesses may likewise equal far-famed. Inward cases, recovery occurs in a few days.
Assiduousnesses of vapor that arrange not causal agency straightaway annoying can have an insidious cumulative essence; symptoms may not be noted until several hours after exposure. Osmium tetroxide molecule is tetrahedral and hence non-polar. These nonpolarity assistances OsO4 come home charged cell membranes. OsO4 is 518 contemporary world more dissoluble in CCl4 than in water. Contact of the vapor with skin can cause dermatitis, and direct contact with the solid can lead to severe irritation and burns.
Osmium tetroxide (OsO4) is in the main exploited either equally a elementary or secondary fixative on membranes for use under electron microscopy in a laboratory environment.
