Which statement about decontamination methods is NOT true?

• A. Distillation
• B. Dilution with water
• C. Rinsing with plain water
• D. Absorption with activated charcoal

Answer: (A)

Decontamination focuses on removing or reducing contaminants from surfaces, liquids, or equipment so exposure is minimized. Distillation isn’t used for this purpose in typical decontamination scenarios. It’s a separation process that relies on boiling points to split components of a liquid mixture, not to remove residues or contaminants from a surface or provide a practical cleanup solution. That’s why it’s not considered a decontamination method. Diluting with water lowers the contaminant concentration, making it easier to reduce exposure to safe levels. Rinsing with plain water physically removes residues from surfaces, which is a direct cleanup action. Absorbing with activated charcoal captures contaminants by adsorption, helping to remove them from liquids or atmospheres. These approaches align with practical decontamination, unlike distillation, which serves purification on a different principle and scale.
