Four members of a family, including an endosulfan victim, reportedly committed suicide in Kerala.

Activists said it was high time the government establish permanent rehabilitation centre for bedridden and mentally-retarded endosulfan victims.

What is Endosulfan :
Endosulfan is an insecticide and acaricide that is being phased out globally. Endosulfan became a highly controversial agrichemical 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 implemented under the Stockholm Convention in 2012, with certain uses exempted for five additional years. 
More than 80 countries, including the  Australia, New Zealand, several West African nations 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. 

What are Acaricides:
Acaricides are pesticides that kill members of the arachnid subclass Acari, which includes ticks and mites.

What are  Endocrine disruptors:
 Endocrine disruptors  are chemicals that may interfere with the body's endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.
