Chemical Weapons Avon Protection

‘Chemical weapons’ refers to the use of toxic chemicals to inflict deliberate harm to humans or animals. They are prohibited by the Chemical Weapons Convention (CWC), which entered into force in 1997 and has been committed to by 193 states. The Organisation for the Prohibition of Chemical Weapons (OPCW) is the international body responsible for implementing the CWC. This includes: verifying the destruction of chemical weapons stockpiles, monitoring certain chemicals and carrying out investigations into alleged chemical weapons attacks.

There have been several reports of chemical weapons attacks in recent years. A Human Rights Watch analysis identified 85 attacks in Syria between August 2013 and February 2018. Joint OPCW-UN investigations in Syria attributed four chemical weapons attacks to the Syrian Government, and two to Daesh. Other incidents include the reported use of chemical weapons in Iraq by Daesh, and the alleged assassination of Kim Jong-nam using the nerve agent VX. In the UK in 2018, four people were taken seriously ill and one person died following exposure to a Novichok, a type of nerve agent.

The international response to events in Syria has included airstrikes on chemical weapons facilities in Syria, official OPCW investigations and a new mechanism to give the OPCW powers to attribute responsibility for chemical weapons use. In the UK, the Government announced a £48m investment in the Chemical Weapons Defence Centre at Porton Down in March 2018, which will include new chemical analysis laboratories. It also announced £11m to strengthen the UK’s response to chemical weapons attacks in March 2019, which will include investment in new technical capabilities for substance analysis and development of plans to deploy robots and drones to contaminated areas. The UK Government’s Modernising Defence Programme, published in December 2018, said that UK defence will focus on chemical, biological, radiological and nuclear (CBRN) threats.

Key Points:

  • A chemical weapons system is made up of several components – a chemical warfare agent, a delivery device and any associated equipment (for example, dispersal equipment). Under the CWC, all these components are considered a chemical weapon if they are intended to cause harm to humans or animals.
  • Many toxic chemicals and precursors are ‘dual-use’, meaning they have legitimate uses but could also be used as weapons. For example, chlorine is used in water purification but could also be used as a choking agent.
  • Chemical weapons attacks can take different forms depending on the capability and the aims of those carrying them out.
  • Policymakers and experts, including the OPCW, have expressed concern over terrorists’ interest in the use of chemical weapons.
  • The OPCW oversees the destruction of chemical weapons stockpiles, carries out inspections and investigates alleged chemical weapons attacks.
  • The UK has led a joint initiative to grant the OPCW powers to attribute responsibility for chemical weapons attacks. Some states are opposed to this move, with concerns it may compromise the politically neutral role of the OPCW.
  • Chemical defence in the UK involves measures to prevent, prepare for, respond to, and recover from a chemical weapons attack.
  • The UK response to a chemical incident involves many agencies working to treat victims, detect and identify hazardous materials, minimise impacts and support investigations.

  • Some occupational groups have experienced higher rates of both COVID-19 infections and related deaths. Many people who work within these groups are involved in caring for people or patients that are more likely to be infected, or have otherwise been unable to work from home during the peaks of transmission. Which occupations have been most affected, what factors are contributing to this risk and are some sectors of the population being impacted more than others?

  • During the first 6 months of the pandemic, people from ethnic minority groups were more likely to have COVID-19 disease and also more likely to experience severe outcomes from infection, including death. Lockdown measures have also disproportionately affected some communities more than others. What is driving this increased prevalence and death rates in ethnic minority groups? To what extent is it due to biology or pre-existing health? Or does it represent a continuation and exacerbation of social inequalities?

  • On 9 September, the Prime Minister announced a moonshot plan for mass COVID-19 testing. Recently there have been capacity issues in the NHS Test and Trace programme and current technologies cannot be scaled easily to millions of tests per day. So, how is COVID-19 testing undertaken, how reliable are current tests, and what technologies or strategies are emerging that would make this moonshot feasible?
