About 60% of the air PM2.5 is caused by coal
Beijing 60% air is contain PM2.5, mainly coal and oil fired Tim Chen, the Beijing Environmental Protection Bureau said that.
For example, he said, the heating of the house on a 100 square meters, each heating season approximately 15 kg of sulfur dioxide emissions, 7 kg of nitrogen oxides, soot four kilograms. Sulfur dioxide into sulfates, nitrogen oxides into nitrates, the formation of PM2.5 both soot emissions, including the secondary conversion of pollutants.
The current Beijing proposed a no thecarbonificated goal, the central city is mainly coal to electricity, the number of urban heating boiler. The suburban districts and counties to strengthen governance to meet the standards; cottage bulk coal user, cooking gas alternative heating using coal.
Vehicles from July 1 will be the implementation of more stringent emission standards
It is understood that Beijing has 5.25 million existing motor vehicles, new car currently enforce the new standards, the old car the old standard, vehicle exhaust emissions already account for about 22% of the total PM2.5.
Tim Chen mentioned in the interview, to July 1 of this year, Beijing will further improve vehicle emissions standards, by raising some of the old heavy-duty diesel engine emissions in the car as well as a new car in the city running low condition standard, to reduce disturbance gas emissions.
"PM2.5 in beijing"
This picture is taken in BeiJing, the terrible air is harm to our life.
According to this article, we can found that the tree are less and almost tree was becoming shrivel. So, it 's necessary to plant more tree around us.
