Tropospheric Ozone Depletion

Tropospheric ozone depletion occurs when certain chemicals, mainly human-made compounds like chlorofluorocarbons (CFCs), destroy ozone molecules in the lower atmosphere (troposphere). Ozone here plays a vital role in filtering ultraviolet radiation and supporting air quality. When these chemicals release chlorine and bromine atoms, they react with ozone, breaking it apart into oxygen molecules and preventing it from performing its protective functions. This process contributes to increased air pollution and health issues, highlighting the importance of controlling emissions of ozone-depleting substances to protect environmental and human health.
