What are the Challenges in Modeling Human Exposure?
Modeling human exposure to chemicals involves numerous assumptions and estimates, which can introduce inaccuracies. Factors such as exposure duration, frequency, and route (e.g., inhalation, ingestion, dermal) need to be accurately represented, yet these factors can vary widely among individuals and populations. Additionally, models may fail to account for all possible sources and pathways of exposure, leading to incomplete risk evaluations.
