Lead exposure can come from more than one route. People may ingest lead by swallowing dust, paint chips, or contaminated food and water, which is why ingestion is a key route. They can also inhale lead dust or fumes, especially during activities that disturb lead-containing materials like sanding or demolition, making inhalation another important route. Additionally, lead can be absorbed through the skin in some circumstances, so absorption is a possible exposure pathway too, though it is typically less significant than ingestion or inhalation. Because exposure can occur through all three routes, the best answer reflects ingestion, inhalation, or absorption. The other options restrict exposure to a single route, which doesn’t capture the full risk picture.
