Symptoms of Lead Poisoning
The signs of mild lead poisoning include diarrhea, irritability, and lethargy.
With higher levels of lead, the symptoms become more pronounced, yet are still difficult to pinpoint to a cause. Children lose their sense of balance and their general cognitive, verbal, and perceptual abilities, developing learning disabilities and behavior problems.
Even more worrisome is that only one year of exposure can permanently impair the brain, nervous system, and psychological functioning.
Recent experiments have shown that the effects occur with lower doses than had been thought in the past. The Public Health Services has singled out lead poisoning as the worst environment threat to children.
