What is the primary means of lead exposure affecting a child?

Water contamination
Food sources
Dust
Paint chips

The correct answer is: Dust

The primary means of lead exposure affecting a child is through dust. In homes, especially those built before 1978 when lead-based paints were commonly used, deteriorating paint can create lead dust that lingers in the air and settles on surfaces. Children are particularly vulnerable to this dust because they often play on floors and surfaces where the dust accumulates and may put their hands or objects in their mouths without proper cleaning. Dust can easily be inhaled or ingested, leading to significant health risks as it contains lead particles. Although other sources like paint chips or contaminated water and food may also contribute to lead exposure, dust is typically the most pervasive and direct route through which children encounter lead in their environment. This makes controlling dust and ensuring safe indoor air quality a crucial aspect of preventing lead exposure in children.
