How Do You Dispose of Chemical Weapons? In the midst of a particularly brutal civil war international attention focused on the Syrian government's use of chemical weapons against civilians.
With a potential deal on the table for Russia to take and store Syria's chemical weapons here is a look at what chemical weapons are and
what it takes to safely dispose of them. Broadly a chemical weapon is a toxic chemical delivered by an explosion such as a bomb artillery shell or missile.
Chemical weapons injure and kill people through horrific reactions including choking nerve damage blood poisoning and blistering.
The first chemical weapons used in World war i were released gases from canisters. Today chemical weapons are carried typically liquids in bombs or shells.
The chemicals like sulfur mustards commonly called mustard gas) or sarin are dispersed in the air like a mist. Technically this means they aren't gases;
World war i saw the first major use of chemical weapons with 124000 metric tons of chemical agent unleashed by nations including the UK Germany and France.'
'Before WORLD WAR II Italy used chemical weapons in Ethiopia and during WORLD WAR II Japan used them in China.
and stockpiled chemical weapons. While the United states never used them in war a declassified CIA document alleges Soviet use during their invasion and occupation of Afghanistan.
Egypt was the first country to use chemical weapons in war after WORLD WAR II. Egypt joined a civil war in Yemen in 1963 where the Egyptian militarty dropped sulfur mustard bombs on enemy troops sheltering in mountain caves.
Chemical weapons appear to have been used against civilians in the ongoing Syrian Civil war between the dictatorial regime of Bashar al Assad and a loose collection of rebel groups.
Syria's chemical weapons stockpile predates the recent conflict. Following a series of military defeats in war against Israel the Syrian government began amassing sulfur mustards sarin and VX (a nerve agent.
The first treaty banning chemical weapons actually predates their use. At the 1899 Hague Convention signatories agreed to not use Asphyxiating or Deleterious Gases.
Currently chemical weapons are banned by the Chemical Weapons Convention a treaty adopted by the General assembly of the United nations that took effect in 1997.
and use of chemical weapons mandates their destruction and encourages international cooperation in chemistry and the chemical trades.
Five countries have not signed the treaty: Angola North korea Egypt South Sudan and Syria. The convention is fairly strict about what counts as a chemical weapon.
Agent orange a herbicide and defoliant used by the United states in the Vietnam war does not count as a chemical weapon under the rules of the treaty
despite the fact that it has been linked to cancer heart disease and birth defects. Al Mauroni director of the USAF counterproliferation center in Alabama and author of Chemical Demilitarization:
Public Policy Aspects tells Popular Science that disposal depends on how the weapon was designed: There are two major ways to dispose of chemical weapons:
incineration and neutralization. Incineration uses a tremendous amount of heat to turn the toxic chemical into mostly ash water vapor and carbon dioxide.
Army Explosive Ordinance Demolition teams would use a 10-to-1 ratio of explosives to suspected chemical weapons.
The United states has nine chemical weapons sites where America's stockpile of chemical weapons is being disposed.
and Mauroni says they both have leakers in their stored chemical weapons so the mobile unit goes out to neutralize the chemical agent.
which are used the components to make a chemical weapon that aren't the weapon itself yet
The countries that have the most experience getting rid of chemical weapons are the United states and Russia owing to their massive Cold war chemical weapons stockpiles.
According to Mauroni Russia had 40000 tons at its peak while the United states amassed around 30000 tons.
which 16 metric tons of chemical weapons that they gave to the United states for disposal. Destruction was completed in 2007
In 1986 Congress passed a law mandating destruction of chemical weapons in the United states and while a tremendous amount of the stockpile has been destroyed the work will continue well into the next decade with the last site set to start disposal in 2020.
It's going to get very expensive very challenging to maintain security to move chemical weapons

That wasn't a leak from the chemical site. Really it wasn't even a leak.

Kelsey's level of ignorance when it comes to chemical weapons is astounding. Its as if he just read a few stories without any fact checking
Most countries with a chemical weapons program today use binary agents. That means there is a primary
Are some chemical weapons easier to destroy than other? There are precursor chemicals which are used the components to make a chemical weapon that aren't the weapon itself yet
and those are easier to dispose because they might have industrial applications and can be sold to companies.

Taste receptors are little more than chemical sensors used by the brain for a purpose. No doubt these receptors are used to assess the condition of the internal organs such as ph fluid content etc. so it's not a stretch to think that taste receptors could be utilized to ensure the proper conditions for sperm production.

This is anything but simple although essentially Zhang and colleagues used chemistry. They worked with a series of synthetic enzymes to break down the hydrogen bonds in some plant material that would not otherwise be used for food like corn cobs and leaves.

However it seems experts identified the wines found in the same shipwreck not by their chemistry but by the appearance of their bottles and corks
