8. According to the table provided in your textbook, the two main pollutants responsible for ozone-layer depletion are
a. Sulphur dioxide and Carbon monoxide.
b. Carbon dioxide and Chlorofluorocarbons
c. ground-level ozone and Nitrogen oxides.
d. Carbon monoxide and Chlorofluorocarbons.
Answer is (d) carbon monoxide and chlorofluorocarbons are responsible for deplition of ozone layer because Indoors or outdoors, the gas can disrupt the transport of oxygen by the blood, leading to heart and health problems. CO also contributes to the formation of tropospheric ozone, another air pollutant with unhealthy effects
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs warm the lower atmosphere of the earth, changing global.
