Sarin has a high volatility (ease with which a liquid can turn into vapour) relative to similar nerve agents, making inhalation very easy, and may even absorb through the skin. A person's clothing can release sarin for about 30 minutes after it has come in contact with sarin gas, which can lead to exposure of other people. [9]
Exposure to large doses of sarin by any type of exposure would likely cause the following harmful health effects: If sarin is in the air, people can be exposed through skin or eye contact, or breathing in the sarin gas. Because sarin vapor is heavier than air, it will sink to low-lying areas and increase the risk of exposure there.
Exposure to even a small amount of Sarin may be fatal, yet treatments are available that may prevent permanent neurological damage and death. Here's a look at how it works and how exposure to Sarin is treated. Sarin is an organophosphate nerve gas—a type of chemical weapon.
Sarin (military designation GB) is a nerve agent that is one of the most toxic of the known chemical warfare agents. It is generally odorless and tasteless. Exposure to sarin can cause death in minutes.
We know that exposure to sarin can result in death, or short-term health effects including seizures, paralysis, and difficulty breathing within 24 hours of exposure. In contrast, long-term health effects of sarin exposure could be observed days, weeks, or years after exposure.
GB is a rapid-acting, lethal nerve agent that affects the nervous system by interfering with the signals sent from the brain to the vital organs and other parts of the body. GB affects the body by...
Exposure to high doses of sarin can result in tremors, seizures, and hypothermia. More seriously, build-up of ACh at neuromuscular junctions also can cause paralysis and ultimately peripherally-mediated respiratory arrest which can lead to death via respiratory failure.
Experimental studies in rats found consistent sarin-related effects on learning and memory that were apparent for days, weeks, and months after sarin exposure. The evidence from human studies for effects on learning and memory during the initial period is inadequate.
Individuals who are exposed to high levels of sarin (for example, levels that results in acute symptoms) may experience long term neurological side effects. These include headaches, fatigue, visual disturbances, memory difficulties, and symptoms of PTSD.
Immediate effects of acute sarin exposure are established; however, whether effects persist after initial signs have subsided is debated. The National Toxicology Program (NTP) con-ducted a systematic review to evaluate the evidence for long-term neurological effects following acute (<24 hour) exposure to sarin.
