- Endosulfan is an off-patent organochlorine insecticide and acaricide that is being phased out globally. Endosulfan became a highly controversial agrichemical[1] due to its acute toxicity, potential for bioaccumulation, and role as an endocrine disruptor.
- Because of its threats to human health and the environment, a global ban on the manufacture and use of endosulfan was negotiated under the Stockholm Convention in April 2011.
- The ban will take effect in mid 2012, with certain uses exempted for 5 additional years.[2] More than 80 countries,[3] including the European Union, Australia and New Zealand, several West African nations,[4] the United States,[5][6] Brazil[7] and Canada[8] had already banned it or announced phase outs by the time the Stockholm Convention ban was agreed upon.
- It is still used extensively in India, China, and few other countries. It is produced by Makhteshim Agan and several manufacturers in India and China.
Several studies have documented that endosulfan can also affect human development.
- Researchers studying children from many villages in Kasargod District, Kerala, India have linked endosulfan exposure to delays in sexual maturity among boys. Endosulfan was the only pesticide applied to cashew plantations in the villages for 20 years and had contaminated the village environment
Endosulfan is a ubiquitous environmental contaminant.
- The chemcial is semi-volatile and persistent to degradation processes in the environment. Endosulfan is subject to long range atmospheric transport, i.e. it can travel long distances from where it is used. Thus, it occurs in many environmental compartments. For example, a 2008 report by the National Park Service found that endosulfan commonly contaminates air, water, plants and fish of national parks
Although classified as a yellow label (highly toxic) pesticide by the Central Insecticides Board, India is one of the largest producers[57] and the largest consumer of Endosulfan in the world
Endosulfan is widely used in most of the plantation crops in India. Toxicity of endosulfan and health issues due to its bioaccumulation came under media attention when health isuues precipitated in the Kasaragod district (of Kerala state) was publicised
India stood against this move owing to pressure from the endosulfan manufacturing companies.[60][19] This flared up the protest,[61][62][63] and while India still maintained its stance, the global conference decided on a globan ban, for which India asked a remission for 10 years. Later, on a petition filed in the Supreme Court of India, the production, storage, sale and use of the pesticide was temporarily banned on 13 May 2011, and later permanently by the end of 2011.
