What is the main source of carbon monoxide (CO) in urban areas?

  1. Vehicle emissions ✓
  2. Industrial processes
  3. Volcanic eruptions
  4. Forest fires

Explanation

Cars produce most urban carbon monoxide. Incomplete fuel combustion creates CO gas. Heavy traffic areas have highest CO levels.

Industries, volcanoes, and fires make CO too. But cities have more vehicles than these sources. Vehicle emissions dominate urban air pollution.

Remember: CO is colorless and odorless. It’s dangerous because you cannot detect it.
