Exposure Assessment

A systematic process of measuring or estimating the intensity, frequency, and duration of human or ecological exposure to environmental agents.

Exposure Assessment

Exposure assessment is a critical component of risk assessment that quantifies how humans, organisms, or ecosystems come into contact with potentially harmful substances or conditions. This systematic evaluation forms the foundation for understanding health risks and developing protective measures.
