129834134006827500_98Yesterday, the municipal environmental protection Bureau publication of Bulletin of the 2011 State of the environment in Beijing shows that air quality levels in the city last year and better than two days reached 286 days. It was published for the last time in this city, "blue sky" data, instead, and members of the public feel more convergence of regional pollutant concentrations.
According to reports, PM2.5, as early as next year, this annual report. "Blue skyAnswer sheet "level increase of 39% compared the city's last good day" blue sky papers "honors. Liu Xianshu said the Director of municipal environmental protection Bureau to monitor, in 2011 the city's air quality levels and better than two days, or "blue sky" accounted for 78.4% of the total number of days. Which days to level 74 days, an increase of 21 days
SWTOR CD-key, an increase of Super-39%. Air quality in mostDifference of level four, five days for 5 days only. In 2011, only Beijing and Shanghai to complete a State-controlled national pollutant concentrations declined the task. The city of sulphur dioxide, nitrogen dioxide and respirable particulates (PM10) declined from the previous year, 12.5% and 5.8% respectively, reducing emissions rate ahead of the national average. Concentration of sulphur dioxide, nitrogen dioxideSecondary standards, PM10 concentrations exceed national standards for secondary 14%. According to reports, starting from this year, environmental quality in government performance appraisal system will be included in the County. Evaluation is no longer in "blue sky", to evaluation of concentrations of major pollutants.
This year, the city requires County-level pollutant concentrations decline or 2%. Why is suspended "blue sky"?Before the Olympic Games in Beijing are the public known as "blue sky" why being "laid off"?
Municipal environmental protection Bureau Director Yu Jianhua said the atmosphere, to cancel the city's reunification of "blue sky" evaluating system and replace it with regional concentrations of pollutants, the environmental monitoring data and the public feel more convergence. Yu Jianhua said
Diablo 3 power leveling, the city area is relatively large, terrain complex and changeable, varying climate conditions, poor weather conditions in different regionsEffects of large, the city's average air quality evaluation results to reflect the actual situation of each region, and members of the public feel the larger differences.
In addition, air quality evaluation of the new system will also be abandoned one-to five-level grading evaluation procedures, direct to evaluate air quality pollutant monitoring absolute value. From now on, 35 PM2.5 monitoring stations will be set up in the city, real time release pollutants concentrationValue, more directly reflect the air quality situation.
People can refer to from their own recent monitoring station monitoring the concentration of values, line, home life and other preparations. Changping Huairou, Miyun County of yanqing optimal air quality monitoring shows that air quality levels in districts of the city last year and better than two days between the 70.9% per cent. Among them, yanqing, and ChangFlat, Huairou, Miyun, and four County "blue sky" are more than 80%.
Only four counties of the city average PM10 concentration reaches the national secondary standard. Last year, the city district, areas with the highest concentrations of sulphur dioxide, nitrogen dioxide, annual average concentration is 0.05 milligrams per cubic metre and 0.071 mg per cubic metre. The public is most concerned about PM10 concentrationMaximum area of Fangshan district, with an average annual concentration of 0.138 milligrams per cubic metre. Monitoring shows that this city eco-environment quality level for good last year.
Eco-conservation in North, Northwest ecological environment condition than urban functions in the area of development and function in the capital district of new development areas, urban development area. Department of environmental protection said, larger pollutants under the influence of weather conditions, the city pollutionSpread from Northwest to Southeast direction.
Is located in Fangshan district, Tongzhou, Daxing and other places in the South higher concentrations of pollutants, dust emissions, industrial and construction, also has a close relationship.
Why air quality declined in the first quarter of this year? From January to April this year, the city's air quality has declined, various pollutant concentrations rose. On this, Yu Jianhua said, since January of this year, the cityRepeatedly encountered adverse weather conditions, the impact of the pollutant, is the main reason for the decline in air quality. Data show that in January last year, the City Harvest 31 "blue sky", and the same period this year, the city of Miyun reservoir, Ming tombs, and other human impacts are small urban background concentrations of air pollutants have increased substantially.
This means that this year, the city's poor air quality and meteorological conditions. "The end of April, the city for 5 days face sand-dust weather and dust over the entrenched in Beijing. Over the same period last year, sand-dust weather affects only the city a few hours at a time.
"Yu Jianhua said, sustained dust directly affects the quality of the air. In addition, the construction site in the city, such as dust, open air barbecue "contribution" of PM2.5, PM10, "large taxpayer", as well as some county-level industrial emissions andMotor vehicle emissions are not well controlled, an important human factor of poor air quality. Poor water quality of the lower river water quality water and eco-city environmental protection Bureau director Han Yongqi said that last year the quality of surface water environment in a slight improvement, water quality in two classes, better than the national standards. But the poor water quality of the lower city, bad class long river water quality monitoring of total length of 436%.
Chemical oxygen demand (COD), total phosphorus targets exceeded. The city's five major river systems, chaobai river water quality in best, yongding river water system second. Stream class water quality deterioration in beiyunhe River long river high. This 22 monitor, Lake, lake water quality monitoring of the surface area of the class, class 85.4%. Round City Lake, Kunming Lake nutrition for "nutrition", "Six sea "as" mild eutrophication ". Han Yongqi, the city's poor water quality of the lower, mainly due to the lack of ecological water, river water main is the sewage treatment plant discharges treated effluent. "If the river water is adequate, full dilution of treated sewage. "He said that, under the current pollutant emissions of large downstream river cleared quite difficult。
River cleared? It is understood that municipal sewage enforcement stepped up to enterprises, last year the city out of the ticket of up to $ 580,000
Diablo 3 gold, illegal sewage enterprises.
Director of total municipal environmental protection Bureau, said Qiao Shufang, this city is no longer the approval need to discharge of wastewater from enterprises, textile, papermaking, printing and dyeing, and other projects were not approved, existing businesses will be phased out. Will Han YongqiLitigation reporter, was tightened in the city effluent standards last year, urban and suburban town of large sewage treatment plant discharges of sewage may reach surface water standards. But he said that, due to the urban development faster, speed far fails to keep pace with the construction of sewage treatment plants, urban water quality to improve the situation is not optimistic.
