Epidemiologist: No safe lead threshold
A visiting expert on heavy metal poisoning says that lead, like asbestos, has no safe level for human exposure.
Bruce Lanphear is an epidemiologist from Simon Fraser University in Vancouver, and he says there are levels of lead in big cities, as well as lead mining and smelting towns, that are dangerous to both children and adults.
This is a transcript from an interview that was conducted on the ABC PM program in 2009. The key point of the interview is that there is no evidence of a "safe" threshold or level for lead and that we must work to bring down exposures.
