Is Osmium Toxins An acutely Toxic Chemical?

Osmium tetroxide (OU) is a naturally occurring element with the hexagonal structure, which is why it is commonly used in the manufacturing industry. The chemical compound itself is noteworthy for its numerous uses, despite the limited availability and its toxic toxicity. It also possesses some unusual physical traits, one of which is its spontaneous reaction to sunlight. The material is semi-solid, however most samples appear orange.

In case of acute exposure, the effects can be quite harmful. The ingestion of minute amounts can cause vomiting, nausea, and diarrhea. The poison is highly toxic and may cause respiratory failure, circulatory collapse, coma, and death in extremely exposed individuals. One who ingests even a very small amount of the chemical may suffer from lasting nausea, vomiting, and headaches. Products containing osmium tetroxide must always be kept out of reach of children.

the substance can lead to dire consequences

There are numerous instances where ingesting too much of the substance can lead to dire consequences. One of the most common uses for it is in the manufacturing of antifreeze. The compounds may cause an antifreeze-like reaction when they come in contact with certain plastics. In July of 2021, officials stopped the use of 4.5% [BY] sodium hypochlorite in new Mercedes cars. The additive is known to generate hypochlorous acid, which may cause corrosion and severe harm to the engine.


There have been several animal deaths attributed to elevated levels of the poison. The Food and Drug Administration warned that a rare but fatal kidney disease known as lithoblastoma was associated with large doses of osmium tetroxide. The disease attacks the kidney causing damage to the tissue. It has since been labeled as a class A drug, which means that it may cause death.


There is additional regulatory information regarding the chemical’s physical properties. US classification standards do not require Osmium Tetroxide to meet emissions or toxicity limits. However, the substance does need a secondary processing treatment, in order to improve its antimicrobial and stability properties. In addition, it needs to undergo what is known as ion exchange to change the molecular ionic charge of the compounds in question.


There is some good research concerning the physical and chemical properties of osmium tetroxide. For example, one study showed that the compound was insoluble in water and could be removed by electrodessication. Another study showed that, under certain conditions, osmium was formed from an organic base, with subsequent development of a nitrogen structure. This study also showed that, under high temperatures, the compound was a potent toxic agent.

the use of osmium tetroxide

Based on these data, there are limited concerns with the use of osmium tetroxide for insecticides. However, when considering insecticidal effects, the safety of the spray itself needs to be considered. There are currently no safe alternatives to the current production methods of most pest control applications. While the use of sub-micron particle size suspension systems is effective for many insects, this is not true for all. The only way to be sure is to monitor the current use of the chemical and, if there is a risk of hazard, make the appropriate changes.


If there are no serious issues with either the workers or the surrounding area, the substance is unlikely to be acutely toxic. However, when exposed to even low concentrations, it can result in dermatitis, irritation, and inflammation. For this reason, people who have been in contact with the chemical should wear personal protective equipment such as gloves and masks. Studies indicate that some strains of cockroaches do not tolerate Osmium Tetroxide at concentrations up to 0.1%. When in doubt, contact with a trained professional is highly recommended.
