Quick explanation

Identify the negative impacts of specific air pollutants, including: (a) carbon dioxide contributing to global warming and climate change, (b) carbon monoxide being a toxic gas, (c) particulates increasing respiratory issues and cancer risk, (d) methane also contributing to global warming and climate change, (e) nitrogen oxides causing acid rain, photochemical smog, and respiratory problems, and (f) sulfur dioxide leading to acid rain

  • This point belongs to Air quality and climate, especially Air quality and climate outcomes.
  • You need to be able to identify the negative impacts of specific air pollutants, including: (a) carbon dioxide contributing to global warming and climate change, (b) carbon monoxide being a toxic gas, (c) particulates increasing respiratory issues and cancer risk, (d) methane also contributing to global warming and climate change, (e) nitrogen oxides causing acid rain, photochemical smog, and respiratory problems, and (f) sulfur dioxide leading to acid rain.
  • The key ideas to know are State.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
