Ozone which is a typical secondary pollutant has become the primary atmospheric pollutant in most cities in our country.Volatile organic compounds(VOCs)are the key precursor to ozone generation.And vehicle emission is the most important source of man-made VOCs emissions.At present,many studies have explored the characteristics of VOCs emissions from vehicle exhaust,but the contribution of different VOCs components to ozone generation is not clear.On the basis of systematically combing the composition of VOCs under different influence factors in the current research,the ozone generation contribution of VOCs and the dominant species of ozone generation were proposed,aiming to provide data reference and theoretical support for the formulation of ozone pollution prevention measures.
