White Phosphorus

Amnesty International and Human Rights Watch have accused the Israel Defense Forces of using white phosphorus munitions in Gaza and Lebanon.

  • White phosphorus is a pyrophoric substance that ignites when exposed to oxygen.
  • It is one among the most unstable of pyrophoric substances.
  • Properties - It emits a distinct garlic-like odour and produces thick, light smoke with intense 8150 Celsius heat.
  • Usage - It is dispersed in artillery shells, bombs, rockets and via felt (textile) wedges soaked in the chemical.
  • Military applications
    • As smokescreen, it hides ground troop movement
    • As an incendiary weapon to start fire
    • Interacts and confuses the infrared optics and weapons tracking systems and protects the forces from guided missiles.
  • Impact on Humans
    • Can cause burns even up to bones.
    • Particles of white phosphorus lodged in the body can reignite if in contact with air.
    • Inhalation causes respiratory damage, harm internal organs.
  • Impact on Environment - It can devastate infrastructure and property, damage crops and kill livestock with raging fires.


  • Ban - White phosphorus is not explicitly banned by international conventions.
  • But their use is regulated under the International Humanitarian Law (IHL).

IHL is established through treaties such as the Geneva Conventions that lays down the responsibilities of states and non-state groups in an armed conflict. It is also called ‘the law of war’ or ‘the law of armed conflict’.

  • Chemical Weapon - It is not considered a chemical weapon because its operational utility is primarily due to heat and smoke, rather than toxicity.
  • Protocol III of the 1980 Convention on Certain Conventional Weapons prohibits incendiaries or the use of other substances to attack civilian populations.
  • Palestine and Lebanon have joined Protocol III, while Israel has not ratified the protocol.

As India continues fighting against dengue, a survey has found that 1in 4 families has fallen ill in the last 3 years due to mosquito-borne diseases.

  • Dengue (break-bone fever) is a viral infection and is the world’s fastest-growing vector borne disease.
  • Caused by – Dengue virus (DENV), a RNA virus
  • Vector - Aedes aegypti mosquito ( which also spreads Chikungunya and Zika virus)
  • Transmission to humans – Through the bite of infected mosquitoes and also possibly by maternal transmission.
  • Occurrence– Tropical and sub-tropical climates
  • Symptoms - While many are asymptomatic or produce only mild illness, it can occasionally cause more severe cases, and even death.
  • Treatment - No specific treatment but early detection and access to proper medical care greatly lower fatality rates of severe dengue.
  • Vector control is necessary.
    • Recently, States such as Andhra Pradesh, Chandigarh and Uttar Pradesh have released Gambusia fish in the waterbodies to control malaria and dengue.
  • Vaccines – Dengvaxia and Qdenga
  • Dengvaxia – It is a live attenuated vaccine which is recommended by WHO for children aged 9 to 16 years.
  • However, only persons with evidence of past dengue infection can be protected by this vaccine.

Dengvaxia was the 1st vaccine for dengue to receive a nod in 2015. It has been licensed in 20 countries but not licensed in India.
