(Reporter Kim Yu) has just begun to be published in Beijing respirable particulate matter (PM10 and PM2.5) real-time concentration, welcome in New Year’s Eve to the first “practical exercise.”
Municipal Environmental Monitoring Center released the real-time data display, from yesterday evening, accompanied by fireworks around the city, the sub-station soaring three conventional pollutants, PM2.5 Chegongzhuang station also soared, from the day’s air quality “excellent” quickly to a slight degree of pollution.
yesterday evening from 5 pm to 7 pm, the capital of the county’s air pollution levels rapidly increased. Previously, a strong north wind by the impact of the spread of pollution in Beijing are strong, yesterday during the day and the county’s three conventional pollutants, sulfur dioxide, nitrogen dioxide and respirable particulate matter (PM10) concentrations of micrograms per cubic meter in a median close to zero micrograms.
but in the evening, three rapid increase in the concentration of pollutants, including PM10 increase of more than the other two particles, a primary pollutant.
before 3 pm yesterday, Haidian Willow Point real-time PM10 concentration does not exceed 10 micrograms, but in the 22:00 to 196 micrograms/cubic meter. Agricultural Exhibition Hall in the Chaoyang District, PM10 concentration in real time at 5 pm to 41 micrograms/cubic meter, 10 pm to 205 micrograms/cubic meter, 5 hours, an increase of 4 times. Before the time of this writing, PM10 is the most dramatic changes in East and eastern station, the concentration of 7:00 pm 78 micrograms/cubic meter, two hours after the 187 into μg/m, and then an hour later, the concentration of 507 micrograms/cubic meters.
Chegongzhuang station PM2.5 concentration of research data in real time to press time yesterday, did not update, stuck in the 8:00 pm, but the same can be seen that the trend of sync with the fireworks. Previous evening after 9 pm to 6 pm yesterday evening, the station real-time PM2.5 concentrations generally in the 60 micrograms/cubic meter. Yesterday, 6:00 pm, and its concentration is 20 micrograms/cubic meter, but an hour later increased to 111 micrograms/cubic meter; to 8:00 pm up to 206 micrograms/cubic meter.
New Year fireworks pollution, mainly due to
Yesterday, many members of environmental organizations and public figures closely watching the new release of the real-time air quality and the relationship between fireworks. Environmental enthusiasts “donkey Stan” in microblogging wrote: “Beijing fireworks were dizzy watching the panic … … contributed several times of PM2.5 pollution.”
Public and Environmental Research Center, Ma Jun, director of micro-Bo said: “The wind decreases, PM2.5 concentrations rising rapidly, sulfur dioxide and nitrogen dioxide concentrations are rising, suggest that you appropriately control the discharge of fireworks.” City EPA is also deputy director Du microblogging in a statement outlining the experience last year: New Year’s Eve 2011, to fifteen, more than 100 API 5 days, which mainly due to discharge of fireworks 3 days, respectively, who started the fifth day, fifteen . Among them, the previous year 1:00 New Year’s Eve, the city’s highest-hour concentration of 760 micrograms/cubic meter, single station to 1390 micrograms/cubic meter. Lantern Festival day 22, the city’s highest-hour concentration of 545 micrograms/cubic meter, single station up to 1308 micrograms/cubic meter, “but also festivals both lively and peaceful, a good release point or less.” Du wrote.
Municipal Environmental Protection Monitoring Center 6 pm last night forecast, although New Year’s Eve spread conditions are favorable, but subject to the impact of the discharge, the concentration of respirable particulate matter will be the peak. Today, Beijing still high during the day and the impact of more favorable diffusion conditions, is expected during the day inhalable particulate matter in the 50 to 90, between the “good.”
