Lead poisoning is a serious health issue for many young children and their families. Lead has been shown to be particularly harmful to children between the ages of nine months and six years. The only way to know for sure if a child has been poisoned is to get the child tested for lead.
Philadelphia’s Lead and Healthy Homes Program works to ensure that Philadelphians have safe and healthy homes, free from lead and other hazards. Landlords and tenants also play an important role in ensuring that rental homes are healthy and safe.
