A recent Federal Advisory Committee has recommended reducing the standard for a child's acceptable lead exposure. The current standard is 10 micrograms per deciliter of blood and the recommendation is to cut this in half. This recommendation has to be approved by the CDC before any change can be effected.

The reduction is based on the premise that any lead exposure can damage a young child's brain. According to a recent article by NPR, an estimated 25,000 children have blood lead levels exceeding the current 10 microgram level. Exposure to lead can create learning, behavioral, cardiovascular and immune system problems. The article encourages testing buildings for lead based paint, rather than waiting and screening children for the lead.
