Question

Quizplus · Accepted Answer

Human health risk assessment often involves extrapolating data from animal studies to humans, which can be problematic due to differences in biology and metabolism between species. Additionally, extrapolating risk estimates to low doses can be challenging as it requires making assumptions about how the body reacts to low levels of exposure, which may not always be accurate.
