• To identify indoor sources and amount of lead in selected households in El Paso and Cd. Juarez.
  
• To measure the amount of lead in the blood of selected children so that researchers can estimate recent exposure to lead in El Paso and Cd. Juarez.
  
• To measure the amount of lead stored in the bone of selected children so that researchers can also estimate long-term exposure to lead.
