What are given as the two examples of secondary pollutants?

Question

BlackTom AI · Accepted Answer

The question asks: 'What are given as the two examples of secondary pollutants?' Since the provided data lists only one item, 'a. Acid rain and smog', and there are no other answer options to compare, we cannot evaluate alternate choices.

Explanation of the given option: Acid rain and smog are classic examples of secondary pollutants. Secondary pollutants are not emitted directly; they form in the atmosphere through chemical reactions involving primary pollutants. For instance, sulfur dioxide (SO2) and nitrogen oxides (NOx) emitted from burning fossil fuels react in the atmosphere to form sulfuric and nitric acids, which lead to acid rain. Similarly, interaction of NOx with volatile organic compounds (VOCs) and sunlight can produce ozone and other components of photochemical smog, which are secondary pollutants formed after emission.

Why this option is correct in context: If the question intends to identify two well-known secondary pollutants, acid rain (from acidic components in precipitation) and smog (specifically photochemical smog from secondary reactions) fit the concept of secondary pollutants.

Why other options would potentially be incorrect if they existed: Typically, primary pollutants are those emitted directly (e.g., SO2, NOx, VOCs in their original form). A correct set of distractors would include statements that fail to recognize the atmospheric chemical transformation needed to form secondary pollutants, or would incorrectly categorize primary pollutants as secondary. Since no additional options are provided, we cannot point to specific incorrect choices here.

In summary, acid rain and smog illustrate secondary pollutant formation via atmospheric chemical reactions, even though the question prompt lacks the other potential options for comparison.
