Final answer:
Other than refrigerants, Nitrous oxide (N2O) is one chemical that contributes to the depletion of the ozone layer. Carbon monoxide (CO) and Sulfur dioxide (SO2), while pollutants, do not directly impact stratospheric ozone depletion.
Step-by-step explanation:
Yes, there are other chemicals besides refrigerants that damage the ozone layer. The primary culprits are chlorine and bromine gases, which can be found in certain aerosols, foams, and cooling systems. One chemical that contributes to ozone depletion is Nitrous oxide (N₂O), which decomposes in the stratosphere to release nitrogen oxides that catalyze the destruction of ozone. Other gases such as Methane (CH₄) can also play a role in altering the concentration of atmospheric ozone, though methane is primarily a greenhouse gas. While Carbon monoxide (CO) and Sulfur dioxide (SO₂) are pollutants that can affect air quality and the environment, they do not have a direct impact on stratospheric ozone depletion. Therefore, the correct answer to the question is a) Nitrous oxide (N₂O).
