Mustard gas is a chemical or iperita agent (Cl - CH 2 - CH 2 - S - CH 2 - CH 2 - Cl) considered by vesicant that causes skin lesions. It was first produced in 1822 in England by Despretz. Causes irritation to eyes and skin sores. If inhaled, can kill by asphyxiation. peek Mustard gas is a liquid, oily, very slightly soluble in water colorless substance.
It was widely used in the last years of World War 1 as a chemical weapon. Currently the use of mustard gas is regulated by the Chemical Weapons Convention (in English: peek CWC Chemical Weapons Convention) as a substance of Class 1, ie no other use unless Chemical Warfare.
The Mustard peek Gas has a powerful vesicant peek action, ie, form vesicles or blisters on the skin with gravity. Also due to its alkylating peek properties (form bonds with the DNA) is also mutagenic and carcinogenic.
Once individuals exposed to mustard gas do not show symptoms immediately and contaminated areas may appear completely normal, it is possible that victims receive inadvertivamente high doses.
At 6 and 24 hours after exposure victims have intense itching and irritation and blisters gradually arise in the skin, containing a yellow liquid. These are chemical burns and are very debilitating.
Symptoms from mustard gas poisoning can occur immediately after contamination, continuing to appear until 12 hours after exposure. And as if that were not enough, the substance may still remain active for a long time, so that the soldiers had their contaminated clothing and equipment died poisoned. If the eyes have been exposed individual will be affected starting peek with conjunctivitis and progressing to temporary blindness. If the Mustard gas is inhaled in high concentrations causes bleeding and blistering peek also damaging the airway mucosa and causing pulmonary edema.
Dependedo the level of contamination, mustard gas burns ranging from first and second degree, may become so severe and disfiguring as third degree. Severe burns can be fatal, death occurring days or even weeks after exposure.
Moderate exposure probably does not kill, however, the victim requires long periods of treatment. Mutagenic and carcinogenic effects of Mustard Gas imply that victims who recover from chemical burns have an increased risk of developing cancer.
