With all the recent hubbub on lead paint-containing toys being recalled and pulled from the marketplace, there is one expert who thinks that lead levels deemed safe for exposure to kids still is too high for comfort.

Dr. Bruce Lanphear believes that the current safe lead exposure guidelines need to be cut in half to really ensure kids remain safe around items which contain the element.

Right now, the limit of 10 micrograms of deciliter is considered "safe" by environmental and medical experts at the Centers for Disease Control, but Dr. Lanphear wants that level cut to 5 micrograms. Is lead-based paint the absolute cheapest way to make paint for children's toys or something?
