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.
