Overview
Pathways
- Today almost everyone is exposed to environmental lead.
- The most potent risk factors in the development of lead poisoning are trough inhalation, ingestion or occasionally dermal contact with lead or lead particles.
Risk Factors
Common Risk Factors
- Common risk factors in the development of lead poisoning include:
- Lead mining and lead smelting, where children and adults can receive substantial lead exposure from sources uncommon today in the U.S.
- Common risk factor in the development of lead poisoning in children in the United States is primarily ingestion of lead particles.
- Inhalation is the second major pathway of exposure. Inhalation also contributes to lead body burden and may be the major contributor for workers in lead-related occupations. Almost all inhaled lead is absorbed into the body, whereas from 20% to 70% of ingested lead is absorbed (with children generally absorbing a higher percentage than adults do).
- Dermal exposure plays a role for exposure to organic lead among workers, but is not considered a significant pathway for the general population, except in areas where leaded gasoline is used. Organic lead from gasoline additives may be absorbed directly through the skin.[1]
