Which of the following causes death by asphyxiation, if its presence in atmospheric air exceeds maximum allowable concentration (i.e. > 50 ppm) ?
Correct answer: C. Carbon monoxide
- A. Benzopyrene
- B. Peroxyacetyl nitrate
- C. Carbon monoxide
- D. Sulphur dioxide
Explanation
Carbon monoxide binds strongly with haemoglobin to form carboxyhaemoglobin, preventing blood from carrying oxygen and causing asphyxiation. The other substances listed are pollutants, but the stated greater-than-50-ppm danger specifically identifies CO.
