A pollution control device apparatus and method reduces contaminants, such as NOx and SOx pollutants, from an effluent gas stream. The pollution control device includes a resonance chamber (16) that ionizes the effluent gas stream. The contaminants of the effluent gas stream are destroyed in a non-thermal plasma reactor (18). The effluent gas is then cooled in a cooling unit (20) to substantially place the effluent gas stream in a non-excited state prior to releasing the effluent gas into the environment or re-injecting the effluent gas into the source (12) of the effluent gas stream. Re-association of the radical oxides into harmful pollutants is thereby substantially prevented.
