Another oddity in Skripal poisoning: OPCW says that 100 grams were used in Salisbury of a poison from which hundreds could die from what fits on the head of a safety match.
On 4 May, a month before the NTV news program was broadcast, the Organization for the Prohibition of Chemical Weapons OPCW amended statements that its leader had earlier given to The New York Times, in which he estimated that 50 to 100 grams of liquid nerve agent had been used in the March 4 attack on the former Russian spy Sergei V. Skripal and his daughter, Yulia, in Salisbury, England. https://www.nytimes.com/2018/05/04/world/europe/opcw-skripal-attack.html
The OPCW stated it would not be able to estimate or determine the amount of the nerve agent that was used in Salisbury on 4 March 2018. The quantity should probably be characterised in milligrams. However, the analysis of samples collected by the OPCW Technical Assistance Visit team concluded that the chemical substance found was of high purity, persistent and resistant to weather conditions. https://www.opcw.org/news/article/opcw-spokespersons-statement-on-amount-of-nerve-agent-used-in-salisbury/
Many competing and contradictory stories promulgated by Russian state-controlled media on the Skripal poisoning https://euvsdisinfo.eu/disinformation-cases/?text=sergei+skripal&disinfo_issue=&date=
On Sunday 4 March Sergei and Yulia Skripal were poisoned in Salisbury with a military-grade nerve agent of a type developed by Russia.

The OPCW have confirmed the UK findings in the case. "The results of the analysis by the OPCW designated laboratories of environmental and biomedical samples collected by the OPCW team confirm the findings of the United Kingdom relating to the identity of the toxic chemical that was used in Salisbury and severely injured three people." https://www.opcw.org/news/article/opcw-issues-report-on-technical-assistance-requested-by-the-united-kingdom/
