Show answer & explanation
Correct answer: A
Concept
Hazardous waste is classified by the property that makes it harmful: toxicity, reactivity, corrosivity, or infectious potential.
Match each example to its defining hazard. Pesticides may be toxic, nitroglycerine is unstable and reactive, acids corrode materials, and used hypodermic needles can carry pathogens.
Application
Waste type | Example | Why it fits |
|---|---|---|
Toxic waste | Pesticide | Toxic pesticides can poison living organisms through exposure. |
Reactive waste | Nitroglycerine | Nitroglycerine is unstable and can react or explode when disturbed. |
Corrosive waste | Acid | Acids can corrode materials and damage tissue. |
Infectious waste | Hypodermic needle | Used hypodermic needles can be contaminated with disease-causing microorganisms. |
Cross-check
Pesticide represents toxicity more directly than corrosivity in this classification.
Nitroglycerine represents reactivity because instability is its defining hazard.
Acid represents corrosivity because it attacks materials and tissue.
A used hypodermic needle represents infectious waste because it can transmit pathogens.
Result
Therefore, the matching is A-IV, B-III, C-I, D-II.
