Endosulfan in Kerala : What is Endosulfan?

Victims of endosulfan poisoning in Kerala’s Kasaragod district have called off their sit-in in front of the state Secretariat in Thiruvananthapuram.

What is EndoSulfan, and how does it work?

  • Endosulfan, also known by the trade name Thiodan, is an organochlorine insecticide that was first introduced in the 1950s.
  • Endosulfan is a pesticide that doesn’t naturally occur in the environment.
  • It’s a crystalline or flakes-like solid with a cream-to-brown color.
  • It has a strong turpentine-like odor to it.
  • It’s used to keep insects out of food and non-food crops, as well as to preserve wood.
  • It’s sold as a blend of two different types of the same chemical (known as – and -endosulfan).
  • In areas where endosulfan is used as a pesticide, it can be released into the air, water, and soil.
  • It’s health effects are determined by the amount of endosulfan you are exposed to and the length of time you are exposed to it.
  • Toxic when inhaled, absorbed through the skin, or consumed.
  • When endosulfan leaks from old godowns were a threat in 2012, they were transferred to new godowns through a scheme called Operation Blossom Spring.
  • Its goal is to bring organic farming back to the district and maintain the ecological balance.
  • Endosulfan is a type of endosulfan that is used to kill bacteria

Whiteflies, aphids, beetles, worms, and other pests are controlled by spraying whiteflies, cashews, fruits, tea, paddy, and tobacco on crops such as cotton, cashew, fruits, tea, paddy, and tobacco.

Endosulfan’s Effects


  • It accumulates in food chains in the environment, resulting in higher doses that cause problems.
  • It is expected to absorb into the sediment and bioconcentrate in aquatic organisms if released into the water.

Animals And Humans

  • Ingesting endosulfan causes a variety of diseases, including physical deformities, cancer, birth defects, and brain and nervous system damage.
  • Endosulfan is prohibited.
  • In 2015, India’s Supreme Court banned the manufacture, sale, use, and export of endosulfan across the country, citing its negative health effects.
  • Both the Rotterdam Convention on Prior Informed Consent and the Stockholm Convention on Persistent Organic Pollutants list endosulfan.

Rotterdam convention 1998

  • The convention aims to promote cooperation and responsibility sharing measures amongst different countries dealing with trade in hazardous chemicals and pesticides.
  • PIC, Prior Informed Consent is the main feature of the convention and is legally binding on the party members.
  • PIC facilitates information exchange about nature and trade-related information amongst the party members.
  • The Convention creates obligations for the implementation of the Prior Informed Consent (PIC) procedure.

Stockholm convention 2001

  • The convention aims to reduce the concentration of persistent organic pollutants (POPs) which are chemical substances that not only remain in the atmosphere for longer periods but also possess the ability to bio-accumulate.
  • The convention listed 12 POPs as ‘dirty dozen’.
