Contributors: Lead poisoning is one of the most common and preventable environmental health problems today. The Centers for Disease Control and Prevention (CDC) establishes the level of 10 micrograms per deciliter (ug/dL) or greater to be the recommended level of concern regarding an elevated lead level. Almost half a million children in the United States are estimated to have elevated blood lead levels of at least 10 µg/dL (micrograms per deciliter). According to 2008 Missouri blood lead testing data, 1,114 children under the age of six were identified with elevated blood lead levels (See Map by County below). What is Lead Poisoning? Lead is a shiny, silver-colored metal found naturally in the earth’s crust. Lead has historically been used in a variety of ways including in paints, gasoline, batteries, bullets, and some vinyl products, such as mini-blinds. Fine particles of processed or recycled lead and/or lead dust become a health hazard when they are taken into the body through inhalation (breathing) and/or ingestion (swallowing). Lead affects almost every organ and system in the body. Lead damages the brain, central nervous system, kidneys, and immune system. Lead in the human body is most harmful to young children under six years of age. It is especially harmful to children less than three years of age due to their rapidly developing and immature body systems. Lead decreases Calcium absorption in the body. This makes it hard for the body to obtain the nutrients it needs to stay healthy. Health Effects of Lead The effects of lead exposure are generally the same whether it enters the body through swallowing or by breathing it in. Often there are few symptoms to indicate a child may have lead poisoning, yet the health effects can be long term. The most common health effects can include but are not limited to the following:
Pathways of Lead Poisoning Lead can be absorbed into the body through the stomach or by breathing it in. Since young children often tend to put things in their mouths, lead can enter the stomach by swallowing contaminated foods, beverages, soil, dust or paint chips. Children are especially vulnerable to inhaling lead dust from deteriorated paint in poorly maintained older housing. A pregnant woman with lead in her body can pass it along to her baby before the baby is even born. The baby can be exposed to lead poisoning if the mother inhales or swallows lead before or during pregnancy. Even if she is exposed to lead before pregnancy, there may be lead stored in her bones that is released into the bloodstream during pregnancy and can be harmful to the baby. Sources of Lead Poisoning -Paint -Mines and Smelters -Soil and dust
-Other sources
Physicians, Parents, Case Managers and Environmental Risk Assessors are Key Reducing the child’s elevated lead level depends on the efforts of an organized team. Physicians and case managers play an important role as members of the organized team, as do parents and environmental risk assessors, in the care of children with elevated lead levels. As an organized group they all work together to provide an important variety of functions, inclusive of but not limited to some of the following:
Also, it’s important for parents to work closely with the other team members to help the lead level go down and prevent further exposures. Better Local Lead Poisoning Resources The Department of Health and Senior Services (DHSS) has a program that is dedicated to Childhood Lead Poisoning Prevention (CLPPP). This program works to assist doctors, and nurses by providing information and methods to screen or test patients under the age of six for lead. State guidelines describe the treatment aspects of children with elevated blood lead levels (EBL) of at least ten micrograms per deciliter (10 µg/dL). Follow-up activities and case management are generally provided for children with an EBL of 10 µg/dL and greater. These activities assist in helping the family understand the causes and health effects of childhood lead poisoning along with interventions that can reduce the current elevation, and help prevent repeated elevations. Lead poisoning prevention educational materials are developed and distributed to help increase both the awareness and needed actions to prevent and reduce lead poisoning within the general public. DHSS works with the local public health agencies (LPHAs), the medical community, other state agencies, businesses, schools, and community organizations in efforts to prevent childhood lead poisoning. Community Lead Poisoning Factors Community factors which increase the risk of lead poisoning include:
Resources for Child Care Providers In areas of the state that are designated as High Risk or Universal Testing Areas, child care providers are given information from the DHSS regarding proof of lead testing requirements, as well as information on how to obtain lead poisoning education materials for use with parents. The Home Environment Most young children spend a great deal of time at their home. That is why it is important to understand that the source of lead poisoning is usually found in the home. The Missouri Public Health System provides lead risk assessments to detect the hazardous sources of lead exposure in children’s homes. This service is provided for children under the age of six who have a blood lead sample from a vein that results in a level of 15 µg/dL or greater. A risk assessment is performed by a professional that is trained and licensed by the DHSS Lead Licensing Program. The assessor speaks with the child’s family to determine areas of the home where the child spends the most time. X-ray Fluorescence Analyzers (XRFs) are used to test dust, soil and water samples to determine if and where lead hazards exist. Upon completing the assessment and receiving the environmental sample results, the risk assessor then provides the property owner and/or occupant (if other than the owner) with information about where the lead hazards are and recommendations for reducing the lead hazards. The risk assessor revisits the home at an agreed-upon time to make sure the lead hazards are reduced and the recommendations have been completed. Barriers at home

What Can I do to Protect Myself and My Family From Exposure to Lead?
Conclusion The effects of lead poisoning cannot easily be seen or felt, but it’s important to know that it can be prevented. There are state, local, and community agencies that can help you understand and prevent lead poisoning. It’s never too early to start using your new knowledge about lead poisoning to help you decide to have your child lead tested, and to help you reduce the likely sources of lead exposure in your home.
