Final answer:
Pica, a craving for nonfood items like dirt and old paint, can lead to lead poisoning in children, resulting in developmental delays, learning difficulties, and behavior problems.
Step-by-step explanation:
Pica, a craving for nonfood items like dirt and old paint, can lead to lead poisoning in children. When the paint peels and cracks, it creates lead dust. Children can be poisoned when they swallow or breathe in this lead dust. Lead poisoning can have serious health effects on children, including developmental delays, learning difficulties, and behavior problems.
