Fine particles in the atmosphere that deteriorate the quality of air come from industrial and transport emissions.

Question

BlackTom AI · Accepted Answer

Restating the question: The claim is that fine particles in the atmosphere that deteriorate air quality come from industrial and transport emissions.

Option 1: True
- The statement accurately reflects a major and well-established source category for fine particulate matter (PM2.5 and PM10). Combustion processes from industry (power plants, manufacturing) and transportation (vehicles, ships, airplanes) release high amounts of fine particles into the air, which contribute to poorer air quality and associated health risks.
- It is important to note, however, that while industrial and transport emissions are key sources, they are not the only sources. Natural sources such as wildfires, dust storms, and volcanic activity, as well as secondary formation from gaseous precursors in the atmosphere, also contribute to fine particle levels. Including these caveats can help avoid an overly narrow interpretation.

Option 2: False
- This statement would be incorrect because it denies the substantial role that industrial and transport emissions play in producing fine particulate matter. Given extensive scientific evidence linking burning fuels in factories, machines, and vehicles to fine particle formation, labeling the statement as false overlooks a major pollution pathway.
- A common misconception addressed here is thinking that fine particles originate solely from natural sources or from non-vehicular activities; in reality, anthropogenic sources from industry and transportation are among the dominant contributors in many regions.

Summary of the thinking: The claim identifies a significant and real source of fine air particulates, though it omits natural and secondary formation aspects. The negative option contradicts established evidence about the role of industry and transport in PM emissions.
