What to Focus On

  • Pollution means harmful deterioration of the environment.

  • Biodegradable pollutants can be decomposed by microbes.
  • Classification by natural fate includes biodegradable and non-biodegradable pollutants.
  • Classification by chemical form includes primary and secondary pollutants.
  • Non-biodegradable pollutants can biomagnify.
  • Air pollution changes the physical or biological characteristics of air.
  • Combustion is a major cause of air pollution.
  • SPM particles are 0.1 to 10 micron in size.

Common Mistakes to Avoid

Pollution is only the addition of dirt or visible waste to the environment.

Pollution is caused only by humans in modern industries, not by human activities in general.

All pollutants are the same, so there is no need to classify them.
