Several factors contribute to scientific uncertainty in toxicology. These include:
Variability in Human Populations: Biological differences, such as age, gender, genetics, and health status, can lead to varied responses to toxins. Limitations of Experimental Models: Animal models often used in toxicology studies may not accurately reflect human physiology, leading to uncertain extrapolations. Environmental Complexity: The interactions between multiple chemicals and environmental factors can complicate predictions of toxicity. Data Gaps: Insufficient data on certain chemicals or exposure scenarios can lead to uncertainty in risk assessments.
