The analyses found no trace of chemical warfare agents in the samples. During the inspection, portable sensors were unable to detect traces of chemical warfare agents and the team's observations led it to conclude that it was unlikely that a chemical weapons attack had occurred at the site inspected. In order to provide greater certainty of this finding, a large number of flora, fauna, water, air and soil samples were taken for laboratory analysis.
Laboratory equipment is capable of much more sensitive analysis.
Analysis was conducted in the laboratories in the United Kingdom and the United States, while the samples in France were kept as controls. Thus there is no evidence to support the allegations of chemical weapons use.
