Four-wheel drive is no match for the mud on the road to a gold mine in northern Nigeria.
September 30, 2012 Gold ore mined in northern Nigeria is mixed with lead. When the ore is dug up, crushed and processed, the lead escapes into the air and settles on the ground. Children are being poisoned when they swallow lead-contaminated dust and dirt.
Don't rely on luck to keep kids safe from lead.
May 16, 2012 The public health honchos agreed with an expert panel that recommended in January that anything greater than 5 micrograms per deciliter of blood for kids 5 and younger should be considered dangerous. That's half the current standard and represents the first reduction since 1991.
Old windows can be a big source of lead contamination.
March 2, 2012 Lead poisoning in children can be reduced by cleaning up pregnant women's homes, according to a new study. That would be better than waiting until children are exposed to identify the problem, experts say. But the cleanups are expensive, and money is tight.
Old paint is the chief source of lead poisoning in children.
January 5, 2012 Children should never live in a house with lead paint, according to a federal advisory committee charged with trying to reduce children's exposure to the toxic metal. The panel recommended lowering the threshold for lead exposure to reflect growing evidence that even slight exposure can harm.
