There is evidence that childhood exposure to lead causes permanent damage

I was going to put this under “mining” in recognition of the the effort put into the data dredging involved

CHILDHOOD exposure to environmental lead has been linked to mental, behavioural and physical deficits, and now the toxic lead dust has been connected to violent assault.

According to US researchers who compared statistics for six cities: Chicago, Indianapolis, Minneapolis, San Diego, Atlanta and New Orleans, rising levels of airborne lead dust lead to spikes in the rates of aggravated assault as exposed children grew up.

The findings, reported today in the journal Environment International, have implications for Australian mining communities, claims Mark Taylor, an environmental scientist at Macquarie University.

“There is an ongoing problem of environmental lead exposure from legacy mining and smelting, as well as contemporary production processes, especially in Port Pirie and Mt Isa,” Professor Taylor said.

The new data comes from Howard Mielke, a specialist in environment and health with Tulane University in New Orleans, Louisiana, and epidemiologist Sammy Zahran, co-director of the Centre for Disaster and Risk Analysis at Colorado State University.

They point to a growing body of scientific evidence that childhood exposure to lead dust causes permanent damage to regions of the brain that govern mood regulation, executive control and judgment.

Professors Mielke and Zahrran found 90 per cent of the variation in aggravated assault across the US cities was explained by the amount of lead dust.

After controlling for other possible causes such as community and household income, education, policing effort, and incarceration rates, they found every 1 per cent increase in tonnage of environmental lead released 22 years earlier, raised the present rate of aggravated assault by 0.46 per cent.

    Same old saw. Correlation is NOT causation, plus brains are found to be always growing, so with removal, IV-chelation, and the right programing, even the brain-damaged from any reason could be improved. Sounds like USA-“shills” for Australian Green-gills (GREEN-Meanie-weenies) of the “No”-police. The Communists of this Era “borrow” ‘experts(spit!)’ of other continents to try to RUIN your gig where you are. Having spent time on Universities, hob-knobbing with students, I KNOW some of them are (–still) ON DRUGS, even some of the Professors, imo.
