${\mathrm{SO}}_2$ and ${\mathrm{CO}}_2$ are responsible for air pollution.

DDT is responsible for water pollution freons are responsible for ozone layer depletion in following way.

$$\begin{array}{rlrlrl}& {\mathrm{CF}}_2{\mathrm{Cl}}_2(\mathrm{g})\stackrel{\mathrm{uv}}{\to }\dot{\mathrm{C}}\mathrm{l}(\mathrm{g})+\dot{\mathrm{C}}{\mathrm{F}}_2\mathrm{Cl}(\mathrm{g})& & & ⟶& \end{array}$$

$$\dot{\mathrm{C}}\mathrm{l}(\mathrm{g})+{\mathrm{O}}_3(\mathrm{g})\to \mathrm{Cl}\dot{\mathrm{O}}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})$$

$$\mathrm{Cl}\dot{\mathrm{O}}(\mathrm{g})+\mathrm{O}(\mathrm{g})\to \dot{\mathrm{C}}\mathrm{l}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})$$

$${\mathrm{CF}}_2{\mathrm{Cl}}_2(\mathrm{g})\stackrel{\mathrm{uw}}{\to }\dot{\mathrm{Cl}}(\mathrm{g})+\dot{\mathrm{C}}{\mathrm{F}}_2\mathrm{Cl}(\mathrm{g})$$

$\dot{\mathrm{Cl}}(\mathrm{g})+{\mathrm{O}}_3(\mathrm{g})\to Cl\dot{\mathrm{O}}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})$

$$\mathrm{Cl}\dot{\mathrm{O}}(\mathrm{g})+\mathrm{O}(\mathrm{g})⟶\dot{}\mathrm{Cl}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})$$
