Question

Why can air inside become more polluted than air outside?

A) Lack of ventilation
B) Higher atmospheric pressure
C) Absence of pollutants
D) Constant exposure to sunlight

Answer 1

Indoor air can become more polluted than outdoor air due to a lack of ventilation and increased exposure to toxic pollutants. People spend more time indoors, which increases their risk of health issues related to indoor air pollution.

Step-by-step explanation:

Indoor air can become more polluted than outdoor air due to a lack of ventilation. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the building. This can lead to higher concentrations of toxic pollutants and a greater health risk. Additionally, people tend to spend more time indoors than outdoors, further increasing their exposure to indoor air pollution.
