How does hot water affect skin absorption of pesticides?

• A. It increases absorption
• B. It decreases absorption
• C. It has no effect
• D. It neutralizes pesticides

Answer: (A)

Hot water increases skin absorption of pesticides because temperature makes the skin more permeable. The outer skin layer becomes more fluid and its barrier function loosens when warmed, allowing chemicals to diffuse through more easily. Warmth also boosts blood flow to the skin, which can move absorbed pesticides into the bloodstream faster. If the skin is exposed to hot water, it may also become irritated or damaged, further weakening the barrier and increasing absorption. For safer handling, use cool or lukewarm water to rinse and avoid hot water, as higher temperatures raise the risk of systemic exposure.
