chemical exposure pathways

Chemical exposure pathways describe how chemicals enter the body. They include inhalation (breathing in fumes or dust), ingestion (swallowing contaminated food, water, or hands), and dermal contact (skin touching contaminated surfaces or substances). Once a chemical enters the body through any of these routes, it can be absorbed into tissues, potentially causing health effects. Understanding these pathways helps identify ways to reduce exposure, such as using protective equipment, proper hygiene, and controlling environmental contamination.
