Exposure assessment comprises several key components:
Source Identification: Determining the origin of the hazardous agent, whether it is industrial, agricultural, or natural. Pathway Analysis: Understanding the pathways through which the agent travels from the source to the receptor. Exposure Point: The location where exposure occurs, such as the workplace, home, or environment. Receptor Identification: Identifying the individuals or populations who are exposed. Exposure Measurement: Quantifying the amount of the agent that individuals come into contact with, using monitoring or modeling techniques.
