Beijing, December 19 (Xinhua) ' Reporter RuiZhen Wang HaiYing Gu) The result of " annual newspaper of prevention and control of pollution of Chinese motor vehicle " revealed in 2011 just released, our country has already produced and sold the first big country as the car of the world for two years in succession, automobile pollution is serious day by day, it is one of the most outstanding, most urgent problems of the atmospheric environment. It shows to monitor, the urban air of our country begins to demonstrate soot and motor vehicle exhaust and compound the characteristic of pollution. Regional air pollution problems such as gray haze, acid rain and photochemical fog of some areas,etc. frequently take place, the cause of these questions is closely related to vehicle emission. Meanwhile, because the motor vehicles mostly go in the densely populated area, it will influence masses' health directly that the exhaust is discharged. The statistical data reveal, 2010, the national motor vehicle will discharge 52,268,000 tons of pollutant, 5,994,000 tons of nitrogen oxides among them, 4,872,000 tons of hydrocarbon, 40,804,000 tons of carbon monoxide, 598,000 tons of particulate matters; NOx and PM that the car discharges exceed 85%, HC and CO exceed 70%. Classify according to the car style, NOx and PM that the national truck discharges are obviously higher than the passenger train, among them the heavy-duty truck is a main contributor; But the passenger train CO and HC emission is obviously higher than the truck. Classify by fuel, NOx that the national diesel vehicle discharges is close to the car and discharge 60% of the total amount, PM exceeds 90%; But the petrol car CO and HC emission is relatively high, exceeds 70% which discharge the total amount. Classified by discharge standard, the standard car before accounting for the country I of car recoverable amount 12.8%, its pollutant discharged accounted for the car and discharged more than 40.0% of the total amount; And account for country and the above standard car of 41.1% of recoverable amount, its emission is less than 15.0% which discharges the total amount. Indicate, classify according to environmental protection, account for the intersection of car and the intersection of recoverable amount and 20.2% " yellow to mark train " only But discharged 70.4% of the NOx, 64.2% of the HC, 59.3% of the CO and 91.1% of the PM. Press spokesman Tao DeTian of environmental protection department says, will continue strengthening working endeavour in the future, implement the nitrogen oxide overall control of motor vehicle in an all-round way, further strengthen the production of motor vehicle, use the overall environment to supervise; Cooperate closely with related departments at the same time, take comprehensive measure from the intersection of trade and development plan, urban public transport, clean the intersection of fuel and the intersection of person who supply and respect, coordinate and move forward " The car, oil, way " Upgrade synchronously, relieve the exhaust of motor vehicle and discharge the impact on atmospheric environment.
