In some areas regional air pollution problems such as acid rain, photochemical smog and haze-prone, and even in some areas there has been more than 200 days a year of haze, which are related to motor vehicle emissions of pollutants such as nitrogen oxide and fine particles are directly related.

Some local acid rain, ash haze and photochemical smog and so on regional the air pollution question frequencies send, the partial areas even appeared every year more than 200 day-long ash haze weather, these all with vehicle emissions nitrogen oxide compound, pollutant direct correlations and so on

Some regional acid rain, haze and smog, and other regional air pollution problems occur frequently, and that some areas have more than 200 days each year the haze weather, these are the motor vehicle emissions of nitrogen oxides (NOx), such as fine particles directly related pollutants.
