Report of 5th #UNSGM Designated Laboratories Workshop at @SpiezLab is online now. I was very honoured to support this in a small way. Exciting work ahead as we move from conceptualisation to operationalisation of a trusted designated lab network >>>

A post-holiday #PandoraReport 11.29 - USAMRIID partially resumes select agent research, @CSIS report on ending the cycle of complacency in US global health security, @OPCW updates and two adopted decisions to amend the Annex #novichok, and much more!

Pandora Report: 11.29.2019

During this holiday time, we’d like to take a moment to thank our readers – we are truly grateful for your support and continued engagement ov...

That's a wrap, #OPCW #CSP24 adopted their report after an afternoon of language negotiations. We leave with updated Schedules (#novichok is now on the control list), a programme and budget for next year, and a nice conference report that will make some great weekend reading (!!)

@IUjvary @TheNonproReview The 5th element contained putative structures of novichok agents different from those published by Mirzayanov. For more info, see “Controlling Novichoks after Salisbury: revising the Chemical Weapons Convention schedules,” by @s_costanzi and @gregkoblentz

Very useful thread explaining a complicated issue but one that shows how arms control treaties can adapt to new realities. For more ideas on how to protect and evolve the CW system of restraint see our brief: @csisponi

Lastly, as @gregkoblentz and I recommended in our @TheNonproReview paper, it will be important to conduct a thorough assessment of key precursors for the synthesis of novichok agents and assess the need to amend the CWC schedules accordingly. #chemical weapons

Moreover, as @gregkoblentz and I recommended in our @TheNonproReview paper, it is advisable to add to the CWC schedules another family of novichoks described by Mirzayanov that still remains uncovered by the CWC schedules. #chemical weapons

To further strengthen the Convention, given that the third element of the Russian proposal contains exclusively a single chemical, it is advisable to further amend the CWC schedules to cover the whole family of chemicals to which this specific chemical belongs. #chemical weapons

The amendment will enter into force 180 days after the @OPCW Director General notifies all State Parties and the Unites Nations Secretary General of the decision reached by the Conference of State Parties. #chemical weapons

In fact, according to the CWC's provisions, any weapon that exploits the toxicity of chemicals to intentionally kill or harm humans or animals is considered a chemical weapon. #chemical weapons @JPZanders

It is worth clarifying that even prior to the addition of these nerve agents to the CWC Schedules, their use as chemical weapons was prohibited by the CWC. #chemical weapons @JPZanders

The carbamates that were just added to CWC Schedule 1 are not chemically related to novichoks and are not organophosphorus nerve agents. However, the biochemical bases of their toxicity are similar to those of organophosphorus nerve agents. #chemical weapons
