In addition to ingestion, how can lead poisoning occur in children?

Lead poisoning in children can occur through various routes, and inhalation is a significant mode of exposure. When lead is present in dust or airborne particles, particularly in environments where lead-based paint is present, children can inhale these lead-laden particles. This is particularly concerning in older buildings where lead-based paints may be deteriorating or during renovations that disturb such materials.

Exposure through inhalation can happen during activities like sanding or scraping lead-painted surfaces or when children play in areas with high dust levels that may contain lead. Once inhaled, lead can enter the bloodstream and lead to various health issues, especially in developing children, who are more susceptible to its toxic effects.

Other options, while they may seem plausible, do not represent the primary pathway for lead poisoning in children within the context of this question. Understanding the routes of lead exposure is crucial in prevention strategies for lead poisoning and protecting children's health.
