RULES WHILE SPRAYING ENDOSULPHAN
Endosulphan should be sprayed at a height of not more than 2-3m above foliage.
Prior information has to be given to people in that particular area .
Advice them to keep away from the area of application for about 20 days.

Exposure to endosulphanBy breathing air near where it has beensprayed.Drinking water contaminated directly or through run-offs.Being in contact with contaminated soil.Eating contaminated food. Smoking cigarettes made from endosulfan contaminated tobacco.Working at endosulfan production centers , direct
ingestion.
EFFECTS TO THE ENVIRONMENT
Endosulfan breaks down into endosulfan sulfate and endosulfan diol, and its residues remains in the soil for around 6 years.
Endosulfan is subject to long range atmospheric transport ,i.e., it can travel long distances from where it is used.
Endosulfan has relatively high potential to bioaccumulate in fish.
Blood glucose levels in fish are elevated.
It is toxic to amphibians and low levels have been found to kill tadpoles
AQUATIC EFFECTS
Health effectsNervous System : Hyperexcitability, tremors, and
convulsions and deathReproductive System & Developmental effects:
Puberty delayed in boys. Infertility among men. Girls attain menarche early. Menstrual disorders are frequent. Has estrogenic effects. Birth defects in offspring of animals ingesting endosulfan during pregnancy
Skin effects: Farm workers with chronic endosulfan exposure are at risk of rashes and skin irritation
Other Systemic Effects: Affects the kidneys & liver. It inhibits leukocyte & macrophage migration. It damages RBC. It causes mutations in mammals & may induce mutations. It is also a potential tumor promoter
SYMPTOMS
Hypersensitive to stimulation, sensation of prickling, tingling or creeping on skin.
Headache, dizziness, nausea, vomiting, in coordination, tremor, mental confusion, hyper excitable state.
In severe cases: convulsions, seizures, coma and respiratory depression.
MAIN CAUSESEndosulfan can also affect human development.
The main disease that has been noticed is skin disease.
Blood cancers, delays maturity among boys ,
Birth defects of the male reproductive system.
AND death
A story of suffering and tragedy in KASARAGOD
KASARGOD
Since India is the largest user of ENDOSULFAN its after effects are being seen in kasagod dst. Kerala.Now, it is a threat to people in Kasaragod
It was sprayed in the cashew plantations in Kasaragod District sine 1976, till 2001 regularly three times every year. The aerial spraying was allegedly undertaken to contain the menace of the tea mosquito bug.
Just after three years, the ill effects of Endosulfan spraying came to notice. As early as 1979, stunted growth and deformed limbs were noticed among new born calves
By 1990’s health disorders of very serious nature among the human population came to the lime light.
Children were found to be the worst affected with congenital anomalies, mental retardation, physical deformities, cerebral palsy, epilepsy, hydrocephalus etc.
Men and women were also affected with various chronic ailments, many irreversible and difficult to treat. There is a high incidence of disorders of the central nerves system, Cancer and reproductive disorders.
The ill-effects of endosulfan used in the cashew plantations of Kasaragod Dist.
Chronology
1976: First experimental aerial spraying of Endosulfan
1979: Poisoning of Endosulfan reported firstly from Kasargod
1994: Issue came forth to public attention and social activists sent complaints to all government officials
1998: The protest emerges as a mass movement 2000: District court banned Endosulfan in

2004: The then opposition leader, VS Achuthananthan deployed his staff to collect available materials and consequences.
2011: VS Achuthanathan led mass fast to ban Endosulfan completely.
2011: Jan 3, Geneva conference decided for global ban
2011: May 13, Supreme court banned Endosulfan
From the mid of 1990’s, the community living near plantations had been complaining against the spraying of Endosulfan. Since then the struggle of the local people have been going on in the courts, in the corridors of power and academies and in the streets.
The struggle got wide support from many within and outside the country. The struggle in Kasaragod became a forerunner for many initiatives against endosulfan spraying and relief measures to the victims.
THE LIVING DEAD…………
Kerala`s endosulfan victims…
Sainaba-whozz overgrowth of head caused her death
RAY OF HOPE…..
Endosulfan-affected Shruti on way to fulfill dream of becoming doctor…
Anti Endosulfan movement emerged in response to these disastrous effects in 1994….
Demands
1.Ban Endosulfan
2. Compensation for victims
Agitations : A massive movement was arouse as the part of struggle in the streets at different stages. A march of thousands of protesters was held on August 2004 demanding Endosulfan Quit – India infront of Kasaragod District Collectorate.The Kasaragod District Panchayath organised a march infront of the Legislative Assemble of Kerala at Thiruvananthapuram demanding to provide relief measures to the victims.
Court Orders :
Court Orders :
In 2003, the High Court of Kerala upheld the order of lower court and it permanently stopped Endosulfan spraying. Thus, the Govt. of Kerala was forced to impose a ban on it’s usage in 2004.It was a welcome relief for the people of Kasaragod. Consequently, the Govt. of India banned the sale and use of Endosulfan in Kerala from 2005 onwards.
The Supreme Court has ordered to give Rs.5 lakh as compensation to the victims of Endosulfan spraying in the villages of Kasargod district in Kerala January 13,2017
CONCLUSIONEndosulfan,a hard to degrade pesticide,has caused
heavy damages to biotic and abiotic factors of KasargodThe fact has been endorsed byvarious pollution control
boards and environmental protection agenciesThat is the main reason why it is banned or yellow-
marked in many countries.Still,Plantation corporation dared to administrates it on
cashew plantation with only a single limitation.i.e, Commercial profit.
The use of endosulfan gave only atemporary yield but lasted with many congential abnormalities,neurological disorders,abortions,epilepsy and other diseases which persists for generation.
The government needs to foccus more on rehabilitating the victims of endosulfan with health,medical,educational,and overall care.
And the time to think of alternatives ways of fertilisation is already passed
Now what we are left with is a few more uncontaminated piece of land and HOPE
Thank you
