Lead poisoning starts when lead builds up in the body, often over a period of months or years. The most common sources of this problem with children come from lead-based and lead contaminated dust in older buildings. Even small amounts of lead can cause serious health problems. Small children under age are especially vulnerable to lead poisoning, which can severely affect mental and physical development. At very high levels, lead poisoning can be fatal even causing death… Please spread the word, make sure you get your children checked and spread the word.
