To address elevated lead exposure in a child, which team composition best ensures a comprehensive environmental assessment and intervention?

• A. Epidemiologist, pediatric specialist, and sanitarian.
• B. Laboratory specialist, contractor whose bid for lead reduction work is the lowest, and public health lead reduction specialist.
• C. Public health sanitarian, pediatric generalist, and plumbing inspector.
• D. Specially trained housing inspector, pediatric specialist, lead-based paint intervention team, and laboratory specialists to test the child's home and the surrounding neighborhood.

Answer: (D)

Managing elevated lead exposure in a child requires a multidisciplinary environmental health approach that can identify and remove lead sources while monitoring the child’s health. The best team brings together a specially trained housing inspector to detect and address lead hazards in the home, a pediatric specialist to evaluate and manage the child’s health risks and coordinate care, a lead-based paint intervention team to plan and carry out safe abatements or renovations, and laboratory specialists to test for lead in dust, paint, soil, and water both in the home and in the surrounding neighborhood. This combination ensures thorough environmental assessment and effective intervention, covering source identification, exposure reduction, medical management, and precise testing. Other configurations miss one or more critical elements, such as clinical expertise, specialized environmental testing, or safe remediation oversight, which can leave the child at ongoing risk.
