Lead affects the nervous system and intelligence. Dr Thuppil Venkatesh,
"There should not be any lead in our blood because lead has no biological function. You and I, living in a society like this, will have about 8-10 micrograms per decilitre. Even at a level of 5 micrograms per decilitre lead can bring about DNA aberrations," he said.
"And in children, anything around 10 micrograms per decilitre can bring down the IQ.
"Half of children in a city like Bangalore already have blood lead levels at about 10 micrograms per decilitre, which has resulted in a reduction in their intelligence quotient. We are seeing more and more cases now because more and more electronic waste is being handled by our people."
