Zorluk: KolayPollution Types, Causes, Effects, and Control

Synthetic chemical compounds released from industrial processes and aerosol propellants can cause significant damage to the atmospheric shield that absorbs harmful solar ultraviolet radiation. Which of the following pollutants is primarily responsible for the destruction of the stratospheric ozone layer?

  1. ChlorofluorocarbonsCevap
  2. B
    Carbon dioxide
  3. C
    Sulfur dioxide
  4. D
    Carbon monoxide

Cevap

Chlorofluorocarbons are primarily responsible for the destruction of the stratospheric ozone layer.
Chlorofluorocarbons (CFCs) release reactive chlorine radicals under high-energy ultraviolet radiation in the upper atmosphere. These chlorine atoms catalyze the destruction of ozone molecules (O3O_3), leading to thinning of the stratospheric ozone layer.

Adım Adım Çözüm

1
Identify the primary environmental role of chlorofluorocarbons (CFCs).
CFCs migrate into the stratosphere where solar UV radiation breaks them apart, releasing free chlorine atoms.
Free chlorine atoms act as catalysts, breaking down ozone (O3O_3) into oxygen molecules (O2O_2) and thinning the ozone shield.
2
Distinguish CFCs from other gaseous air pollutants.
Carbon dioxide drives global warming, sulfur dioxide causes acid rain, and carbon monoxide binds hemoglobin, making chlorofluorocarbons the specific agent of ozone depletion.
Differentiating pollutant mechanisms ensures accurate identification of causes and ecological consequences.
