Statement I: Indoor solid fuel combustion is a minor health concern compared with ambient pollution.

Statement II: Concentrations in an unvented kitchen can exceed outdoor levels by a factor of twenty.

In the light of the above statements, choose the correct answer.

  • A.Both Statement I and Statement II are correct
  • B.Both Statement I and Statement II are incorrect
  • C.Statement I is correct but Statement II is incorrect
  • D.Statement I is incorrect but Statement II is correct

Answer: D

Correct answer: Statement I is incorrect but Statement II is correct

Statement I is incorrect. Household air pollution from solid fuel combustion is among the largest environmental health burdens worldwide, responsible for millions of premature deaths a year - not a minor concern.

Statement II is correct and is why: concentrations in an unvented kitchen can exceed outdoor levels twentyfold, and the exposure is concentrated on the women and young children who spend most time near the stove. The ambient monitoring network cannot see any of it, which is part of why the problem was recognised late.
