Routes of Chemical Exposure: Skin Absorption, Ingestion, and Inhalation #144192 (License: Personal Use)

The image presents a clear, black-and-white schematic showing three silhouetted human figures, each demonstrating a distinct route of exposure: arrows indicate substances penetrating the skin (dermal absorption), entering the mouth and traveling down the esophagus to the stomach (ingestion), and being drawn into the trachea and lungs (inhalation). Each pathway is labeled beneath its respective figure for immediate comprehension. The design emphasizes anatomical accuracy while maintaining simplicity for educational use.

This image is commonly used in occupational health and safety training, toxicology education, environmental risk assessments, and public health communications to illustrate exposure pathways. It supports user intent to understand how contaminants reach internal systems and informs protective measures like PPE selection or ventilation strategies.
