‘There is a widespread consensus now that there is no safe level [of lead]’
BBC Radio 4: In their element – lead listen again here.
The striking thing is the passage where the point is made that as techniques have improved it has become possible to demonstrate that lower and lower amounts of lead still have an impact – we are all suffering from lead poisoning to some extent.
Doesn’t make sense to keep shooting it into our food then does it when non-toxic alternatives are readily available and used widely elsewhere in the world?
Those shooters who argue for continued use of a poison to cull species which enter the human food chain should realise that ‘…children with higher exposures in childhood had reductions in the volume of certain areas of the brain, most notably in the frontal areas of the brain, the frontal cortex, which lines up well with the clinical presentation of someone who has been overexposed to lead. They have problems with executive functioning, with planning, with impulse control, ability to delay gratification and so on. This is really very compelling information that shows that there are long-term persistent, possibly permanent, effects of early childhood exposure that will be expressed in later life.’ David Bellinger, Prof of Neurology, Harvard Medical School.
