Match List I with List II Choose the correct answer from the options given below:LIST I (Type of wastes) LIST II (Example) A. Toxic wastes I. Acid B. Reactive wastes II. Hypodermic needle C. Corrosive wastes III. Nitroglycerine D. Infectious wastes IV. Pesticide
A-IV, B-III, C-I, D-II
Hazardous wastes are classified according to the type of danger they pose, and each category can be illustrated with a characteristic example, as matched below.
| List I (Type of waste) | List II (Example) |
|---|---|
| A. Toxic wastes | IV. Pesticide |
| B. Reactive wastes | III. Nitroglycerine |
| C. Corrosive wastes | I. Acid |
| D. Infectious wastes | II. Hypodermic needle |
Toxic wastes such as pesticides are poisonous even in small doses and can cause illness or death upon exposure, ingestion or inhalation.
Reactive wastes such as nitroglycerine are chemically unstable and can explode or react violently under normal handling, releasing heat and toxic gases or causing detonation.
Corrosive wastes such as strong acids can chemically destroy living tissue and eat through metal containers on contact.
Infectious wastes such as used hypodermic needles carry disease-causing pathogens and pose a biological hazard if not disposed of safely.
Hence, the correct matching is A-IV, B-III, C-I, D-II.
