Nanjing PM2.5 fell the first in the province
As of December 6, this year, the air quality in the built-up area of ​​Nanjing was 226 days, and the compliance rate was 66.5%, up 14.7 percentage points year-on-year. The average concentration of major pollutants in the air improved significantly year-on-year, with PM2.5, PM10, SO2 and NO2 decreasing by 27.0%, 23.8%, 20.8% and 7.5% respectively over the same period of the previous year. According to the results of the provincial atmospheric office, by December 6, the average concentration of PM2.5 in Nanjing was 54 μg/m3, which was 25.9% lower than that in the same period of 2013, ranking the first in the province.
The person in charge of the Nanjing Motor Vehicle Exhaust Pollution Supervision and Management Center introduced that in the area of ​​motor vehicle pollution prevention and control, Nanjing continued to deepen the measures for restricting high-pollution vehicles, and the scope of restrictions was extended to the area of ​​555 square kilometers in the area around the Yangtze River. It was also extended from the initial part of the time to 24 hours a day.
A monitoring and management system is established for diesel vehicles with excessive exhaust gas (commonly known as smoky vehicles), and mandatory measures such as deadline treatment are implemented for smoky vehicles.
This year, Nanjing also took the lead in setting up a motor vehicle environmental protection police office in the province to strengthen the law enforcement inspection of vehicles. Focusing on environmental law enforcement inspections, special law enforcement inspections such as supermarket shuttle buses, yellow-green vehicles, and black smoke buses were launched. Strengthen the prevention and control of oil and gas pollution, promote the online monitoring and construction of oil and gas pollution, and investigate and deal with illegal activities of idle oil and gas recovery facilities. Strengthen the promotion of motor vehicle pollution prevention and control. Promote the elimination of the remaining yellow-label vehicles and encourage the elimination of highly polluting vehicles.
Yellow label car eliminated 95.5% in 3 years
The management system and measures for the use of vehicles in the prevention and control of motor vehicle pollution mainly include the periodic inspection system for the prevention and control of motor vehicles, the management system for environmental protection signs, the restricted traffic system for high-pollution vehicles, the establishment of environmental protection concepts for publicity and education, and the elimination of yellow-label vehicles. Enforce laws and regulations, etc. These systems and measures are effective in reducing vehicle pollution emissions, keeping highly polluting vehicles away from urban living quarters, and improving ambient air quality.
Taking the yellow label vehicle as an example, according to the requirements of the relevant departments, in 2013, Nanjing started the comprehensive elimination of the yellow label vehicle. There are 66,672 yellow label vehicles in the city. At present, 63,666 vehicles have been eliminated, and the elimination rate has reached 95.5%. The yellow label car that was eliminated realized an annual emission reduction of 67,500 tons of motor vehicle pollutants, including 46,200 tons of carbon monoxide, 0.64 million tons of hydrocarbons, 13,500 tons of nitrogen oxides and 0.144 million tons of particulate matter, reducing the number of motor vehicles in the city. 30.3% of pollutant emissions.
