São Paulo - The chemical weapons of mass destruction allegedly stockpiled in Syria have become a concern worldwide. A few days ago, a spokesman for the Syrian President Bashar al-Assad admitted that the country possesses such weapons by stating that only would use in case of foreign aggression. The threat of Assad may even be a bluff. But even if these weapons are used in an attack, can cause extreme suffering and death to thousands chlorine of people. The use of chemical weapons (as well as biological weapons) was banned by the Geneva Convention, which entered into force in 1928. Even so, these weapons continued being manufactured. The Chemical chlorine Weapons Convention, adopted by the UN in 1992, detailed the timeline for closing the manufacture and stockpile destruction. chlorine This process is well underway.
Syria, however, is one of seven countries that are not part of the agreement. According to the Global Security website specializing she is also one of the four countries with confirmed chemical arsenals (the other three are the U.S., Russia and North Korea). The site estimates chlorine that the Syrians are able to manufacture a few hundred tonnes per year of chemical agents.
Moreover, there is little doubt that the armed forces have missiles and artillery projectiles capable of performing chemical attacks. But no one knows exactly which weapon spokesman Assad noted. See, then, what are the most common variants of such weapons and what effects they can have on humans.
These gases produce extremely painful burns to skin, eyes and respiratory tract. The name "blister agents" comes from the fact they cause huge blisters chlorine on the skin. Are cytotoxic substances that destroy DNA and lead to cell death. The victim may agonize chlorine for weeks before he died. If she survives, tends to develop cancer.
The best known of these gases, the mustard was invented chlorine in Germany in 1916. Was used during the First World War by the Germans initially and then also by the British. In the '80s, the mustard was one of the lethal gas used by Iraq in the war against Iran An Iraqi attack against the Kurdish population has resulted in the deaths chlorine of 5000 people. The nerve gases are among the most feared chemical weapons, since just a small amount to cause the death of many people. Are organophosphorus compounds that destroy the mechanism of transmission of nerve impulses. The victim loses control of muscles and suffer violent convulsions until it can no longer breathe and dies.
The oldest of these gases, tabun, was invented in Germany in 1936 by Gerhard Schrader, chlorine who was researching insecticides. Schrader then went on to develop chemical weapons and discovered sarin, ten times more potent than tabun. The two gases were produced industrially in Germany during World War II and incorporated into artillery shells. But there came to be used on the battlefield. In 1995, the Aum Shinrikyo cult carried out a terrorist attack with sarin in the Tokyo subway diluted, killing 13 people.
These gases cause skin burns in the eyes. Also cause damage to respiratory system which lead to accumulation of fluid in the lungs. Over time, the victim suffers cardiac arrest and dies. Are one of the oldest chemical weapons. There are reports that chlorine gas was used as stifling by the British in the Crimean War, between 1853 and 1856. Another greenhouse gas, phosgene was first synthesized in 1812 in England.
In World War I, Germany employed both chlorine and phosgene as weapons. Phosgene, more effective, it was also used by France, England and the United States. It is estimated that this gas has been responsible for 85% of the more than one hundred thousand deaths caused by chemical weapons in that war.
The base are poisonous cyanide or arsenic gases. They enter the bloodstream and prevent the transport of oxygen by red blood cells. The victim feels pain, suffering seizures, falls into a coma and dies. Although deadly indoors, these gases disperse rapidly outdoors. Therefore, there is no record of having been employed as a weapon-examination war
