Which effect is associated with sulfur dioxide emissions?

• A. Acid rain and respiratory issues.
• B. Warming of the atmosphere only.
• C. Not harmful to health.
• D. Improves crop growth.

Answer: (A)

Sulfur dioxide emissions are linked to acid rain and respiratory irritations. When SO2 enters the air, it reacts with moisture and oxygen to form sulfuric acid aerosols. These aerosols and the acidic rain that forms lower the pH of rain, soils, and water bodies, damaging ecosystems, corroding buildings, and harming forests. At the same time, inhaling SO2 or its fine particles irritates the respiratory tract and can worsen asthma and other lung conditions. The other ideas aren’t accurate: sulfur dioxide isn’t primarily known for warming the atmosphere ( its airborne aerosols can actually have a cooling effect in some contexts, but that doesn’t capture the main health and environmental harms); it is harmful to health; and it does not improve crop growth.
