Western and Israeli officials advocate the use of chemical weapons in Syria quoted photos sporadic shelling and traces of the toxin, does not meet the standard of proof need to wait to collect scene evidence team of experts for the United Nations.
Weapons inspectors can only determine whether or not to prohibit the use of chemicals is used for 2-year-old conflict, if they are able to access the site, and take soil, blood, urine or tissue samples, and check their certified laboratory, according to prohibit histochemical Weapons (OPCW), check with the United Nations.
This type of evidence clearly shows that if found illegal chemical has not been put forward by the government and intelligence agencies accused Syria of using chemical weapons against the rebels.
"This is the OPCW will provide the sole basis for a formal assessment of whether it has been used for chemical weapons," said Michael Lujan, spokesman for the Prohibition of Chemical Weapons (OPCW) in The Hague.
With Syria to stop the United Nations mission, this is not possible, any time soon, they will get this type of access.
United Nations Verification Mission, the person in charge of the Swedish scientist Ake Sellstrom will meet with UN Secretary-General Ban Ki-moon in New York on Monday.
The United Nations on Thursday again wrote to the Syrian government the to promote the UN investigators unconditional and unfettered access, Ban Ki-moon's spokesman Martin Nesirky told reporters on Friday.
"The Secretary-General urged the Syrian government responded quickly and favorably, this task can work in Syria, Nesirky said." "You need to be able to enter Syria to correct investigation."
"In the meantime, the team members organize and analyze the evidence and information from the outside," he said, adding that so far, there is a concern "evidence" of Syria degradation.
The White House said on Thursday that the U.S. intelligence community to assess the use of chemical agents, sarin confidence with President Bashar al-Assad's forces allied. But it pointed out that "the chain of custody is not clear."
Around the problem of 'physiological' samples
The Israeli army this week recommended that the Syrian army sarin nerve gas cause of death showed reporters photos of physical symptoms.
Ralf Trapp, chemical and biological weapons control, an independent consultant said, "You can extract from the photo evidence is limited, you really need to get information from the ground to collect physical evidence speak witnesses and medical personnel to treat the victims. "
The nerve agent sarin is a fast, initially in Germany in 1938 as a pesticide. It is a clear, colorless, tasteless, odorless liquid, can quickly evaporate into gas and dispersal into the environment, according to the U.S. Centers for Disease Control and Prevention.
Because it is so rapid evaporation, sarin provide an immediate, but short-lived threat.
Emory University biodefense expert, the former CDC public health preparedness and research centers Sean Kaufman said, have been exposed to sarin most typical people dead or fully restored. Sarin test, he said, someone accesses environment requiring nerve gas or revealing clothing.
White House, calling for Syria's use of chemical weapons in the "red line" for a possible military intervention, saying that its assessment is based in part on the "physiological" sample. But a White House official declined to be named, declined to elaborate the statement evidence. It is unclear who provided.
Even those who assert to the OPCW samples, the organization can not use them.
Luhan OPCW will never set foot in a test sample, our own inspectors gathered at the scene, said: "Because we need to keep from the field to the laboratory sample chain of custody, to ensure its integrity.
The OPCW established for the implementation of the 1997 Chemical Weapons Convention, prohibit the use of toxic substances in the war, detailed inspectors how to collect and deal with the rules of evidence, starting a website is like a crime scene seal.
Multiple samples must be taken, "blank" has never been exposed to this matter, and tissue samples, set the baseline, to determine the level of pollution.
Samples will be split, seal, in the dark, the cooling air to the flight of three certified laboratories, including at the OPCW headquarters in The Hague.
Cyprus nearly three weeks, a team of 15 experts, together, survey claims requests the Secretary-General of the United Nations, has been on standby.
Led by Sellstrom, which includes analysis of the chemist and the World Health Organization expert medical effects of exposure to toxins.
