Nitrogen oxides are one of the main causes of haze weather. There are many ways to eliminate nitrogen oxides.

Judging from the situation in Beijing, the distribution of PM2.5 and smog is not synchronized with the distribution of nitrogen oxides, nor is it related. Some places are smog of regional input type. .

However, there are more nitrogen oxides in the air, which will indeed aggravate pollution and contribute to smog.

The key to eliminate nitrogen oxides is to reduce coal consumption and improve automobile exhaust emission standards. When the tail gas detection is raised above Euro 4 standard, the emission of nitrogen oxides will be reduced by more than 60% compared with Euro II standard.
