Endosulfan Could Delay Sexual Maturity
 Studies
conducted in a village in Kerala, India, have confirmed that the pesticide
Endosulfan has deteriorating effects in the development of reproductive system in youngsters.
During the research, it was found that male children exposed to
Endosulfan showed delayed sexual maturity as opposed to another group of children, who were living in healthier conditions untouched by the pesticide.
The experiment further revealed that the chemical also interferes with sex hormone synthesis. Despite its negative effects, it is interesting to note that
endosulfan, even though it is not manufactured, is widely used in the cultivation of crops such as pecans, squash, and strawberries in US.
The chemical however already carries a ban in countries like Germany, Cambodia, Sweden, Colombia, Norway, and Indonesia, and is severely restricted in 20 other countries across the globe. But, it is a disturbing fact is that
endosulfan is still used in many third world countries.
The study on the effects of endosulfan on human reproductive system was published in the journal
Environmental Health Perspectives (EHP). The research team studied 117 children, who were living in areas where
endosulfan had been aerially spraying for more than two decades, and compared the observations with that obtained from 90 comparable children, who were living in a neighboring village with little or no history of
endosulfan use.
The research team performed comprehensive physical examinations and recorded sexual maturity rating, clinical history, and blood levels of various hormones for each group and juxtaposed their findings before drawing the final conclusion. The differences in the observations made the research team to conclude that there is a possible delay in attaining sexual maturity in children who have had long exposures to
endosulfan than those who had not.
The team further noted that since endosulfan spraying in Kerala had been banned in 2000, even months later, people who were staying in the village still bore higher concentrations of the chemical in their serum than in the control group. This observation underlines the persistence of
endosulfan in blood.
According to the editor of Environmental Health Perspectives (EHP), it was a unique study conducted ever in this world for the village where the research team had camped to make observations was one such hamlet where only
endosulfan had been used as a pesticide in the past and nothing else.
He further adds that even though the sample size was too low to generalize the phenomenon, the apparent findings that points to the negative effects of
endosulfan in sexual maturity and sex hormone synthesis is definitely compelling enough to call for further studies and banning of the particular chemical from commercial use. Is anybody listening?
