It turns out it takes half as much lead poisoning to cause problems for children than previously thought, prompting concern that more Pennsylvania children could be at risk.
 
The CDC recently cut in half the level of exposure deemed to be a problem.
 
In the meantime, Congress allocated only 2 million for lead-poisoning prevention this year compared to 29 million the year before. That leaves very few staff members to get the word out. Medical toxicologist Dr. Jennifer Lowry, says it also means that it's now up to parents and pediatricians to become more proactive.
 

 
Dr. Lowry suggests that doctors go to the CDC website and make themselves aware of the new guidelines. She also recommends that parents talk to their pediatricians about testing. New studies have found attention problems and reduced IQ in kids who are within the new guidelines. Sources of lead include toys, children's jewelry, paint chips from old homes, and sometimes even the soil around homes.
