A photochemical smog always contains ozone.
A ‘photochemical smog’ is a substance that is formed during summer, the substances that are present in the atmosphere at summer such as the nitrogen oxides and the volatile organic reactive species in the presence of “sunlight” forms the ozone.
The “nitrogen oxide” content is increased almost about 75% in the atmosphere presently due to the increasing number of automobiles that uses petrol as fuel.
