Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What is the purpose of an EBL investigation?

1. Assessing lead paint exposure in adults

2. Identifying sources of lead poisoning in a child

3. Monitoring lead levels in drinking water

4. Evaluating paint quality

The correct answer is: Identifying sources of lead poisoning in a child

An EBL (Elevated Blood Lead) investigation is specifically designed to identify sources of lead poisoning in a child. When a child presents with elevated blood lead levels, it is crucial to conduct an investigation to determine the possible sources of exposure. This process involves evaluating the child's environment, which may include their home, toys, and any other potential sources of lead. Understanding the pathways through which lead enters a child's system is essential for developing an effective intervention plan to mitigate future exposure. The investigation may involve visual assessments of paint, dust, soil, and plumbing as well as interviews with caregivers to gather information regarding the child's activities and environment. This targeted approach is vital for both protecting the child's health and addressing any identified hazards to prevent further lead exposure. In contrast, while assessing lead paint exposure in adults and monitoring drinking water lead levels are important public health concerns, they do not specifically address the immediate need to pinpoint and eliminate sources of lead poisoning in children, nor do they focus on individual investigations based on elevated blood lead levels. Evaluating paint quality does not address lead exposure or health impacts, making it irrelevant to the purpose of an EBL investigation.
