What Are the Challenges in Human Exposure Assessment?
Despite advances in technology and methodology, assessing human exposure poses several challenges:
Complex mixtures: People are often exposed to complex mixtures of chemicals, making it difficult to assess individual contributions to toxicity. Variability: Differences in individual lifestyles, behaviors, and environments lead to variability in exposure levels. Data gaps: Lack of data on certain chemicals or exposure scenarios can hinder accurate risk assessments.
