Chemical pollution is pollution caused by chemical substances that are normally absent from the environment, or present in concentrations that are naturally (much) weaker.
Chemical pollution is therefore a specific category of pollution. In fact, pollution is classified according to the nature of the pollutants (chemical, physical or biological) or the specific environment affected (air, water or soil pollution).
Industrial smoke is both chemical pollution and atmospheric pollution, depending on how this type of pollution is classified. © nevadog CC by-nc-nd 2.0
