Which term describes how poisonous a pesticide is to man or animals when breathed in through the lungs?

• A. Inhalation toxicity
• B. Dermal toxicity
• C. LC50
• D. LD50

Answer: (A)

Inhalation toxicity describes how poisonous a pesticide is when it is breathed into the lungs. This term focuses on the respiratory route of exposure and the toxic effects that occur from inhaling the chemical. It’s the general way we categorize toxicity for air-borne exposure, and it’s often connected to measurements like LC50 in inhalation studies, which quantifies the concentration in air that kills 50% of test subjects. The other options don’t fit the inhalation route: dermal toxicity is about skin exposure, LD50 is a lethal dose by any route, and LC50 is a specific concentration value rather than the descriptive term for inhalation toxicity.
