Which term describes the amount adjusted for body characteristics such as weight?

• A. Concentration
• B. Dose
• C. Dosage
• D. Exposure

Answer: (C)

The idea here is standardizing the amount of chemical by body size so you can compare across people of different weights. This is described by dosage, which expresses the dose per unit body weight (for example, mg per kg). That normalization lets risk assessors evaluate potential effects consistently for both small and large individuals. Concentration, on the other hand, is a ratio of substance to volume in the environment and doesn’t account for body size. Dose is the actual amount that enters or reaches the body but isn’t adjusted for body weight. Exposure refers to contact with the chemical, not the internalized amount. So, the amount adjusted for body characteristics such as weight is dosage.
