What to Focus On

  • Pollution is the addition of harmful contaminants or energy to the environment.
  • Monitoring helps study pollutant levels, trends, and control effectiveness.
  • Primary pollutants enter the atmosphere directly.

  • Air pollution harms humans, crops, animals, and built structures.
  • Primary pollutants are emitted directly from sources.
  • Secondary pollutants are formed by reactions in air.

  • CPCB is the apex pollution-control body.
  • CPCB was established in 1974 under the Water Act.
  • CPCB later received powers under the Air Act, 1981.

Common Mistakes to Avoid
