Severe smog in Wuhan， and neighboring provinces of crop straw burning was the main result

Wide central Wuhan, June 14 (Wuhan station reporter Zuo Jian), according to report in the news aspect of urban air were Khaki, filled with thick smoke, many people feel the throat discomfort and stinging eyes. This is the last two days in Wuhan, Hubei, people in Twitter's "ridicule". Starting from 12th in Wuhan since the Spring Festival this year suffered its worst haze hit.

12th at five or six o'clock in the afternoon, visibility to about 1 km in some areas, visibility is only hundreds of meters in some areas. Across the River in Wuhan 9 ferry routes overall have been suspended. Best how bad the smog? We take a look at Wuhan, the intuitive feeling.

Public 1: not feeling very well today, my nose can't breathe and dry inside, all there is lots and lots of hard Emery wheel. Ordinary air is good and I would come out and exercise today will certainly not come out.

Citizen 2: I feel feel feel like breathing in breathing, gray, go back to diet, eat more fruit of Qingfei.

It is understood that, Wuhan City, the smog was first encountered both PM2.5 and PM10 "table burst". Concentrations of PM2.5 hour value is more than 800 micrograms/cubic meter, the air quality has reached high levels of pollution levels, the country last. Ambient air monitoring center in Wuhan City Environmental Protection Bureau senior engineer Li Pu lists several data.

Li Pu: 15 o'clock in the afternoon and comprehensive data, data than at 5 in the morning, PM2.5 have risen by a factor of 4 times, PM10 increased by 3.5 times.

Wuhan where does smog come from? Emergency Office of Wuhan municipal government via its official Twitter reported that factories, mines, industrial enterprises in Wuhan without incident and excessive emission events. Ambient air monitoring center in Wuhan City Environmental Protection Bureau said senior engineer Li Pu, depending on meteorological conditions, as well as satellite monitoring of the Environmental Protection Department said the fire point, we can judge: Hubei provinces around burning straw, Wuhan main causes of the severe smog days.

Li Pu: laboratory test data, organic carbon, elemental carbon, and metals maintain a continuous upward trend in measurement of concentration of potassium ions. 15-point detection of organic carbon concentrations 10 times higher than at 5 in the morning, elemental carbon and potassium ions increases by 8 times. Based on the monitoring data, we initially determined, today's ambient air quality to be under the influence of straw burning in Wuhan.

MEP Argos Centre for applied remote sensing monitoring of crop straw burning daily release said, were monitored to Hebei, Henan, Anhui, Jiangsu and Shandong straw burning fire to 162. Smoke in these areas along Northeast into Hubei. Monitoring data show that of elemental carbon, potassium ions in the air monitoring values increased by 8 times. This is after the straw burning of two main elements.

It is understood that except around the burning straw, haze days with Wuhan, the recent weather conditions are not unrelated. Analysis of Wuhan City Meteorological Department said the early 12th, Wuhan air inversion occurred about 1000 meters, like a lid over the Wuhan, not upward movement of pollutants in the air, stuck close to the ground, causing haze intensity, long duration. 13th, the smog in Wuhan although alleviate this somewhat, but still continues.

This morning, the reporters found in Wuhan second Yangtze River Bridge North of the bridgehead, in the ordinary days of good weather, where you can clearly see the river South Bank building, but today's buildings are along the Yangtze River in the looming fog inside. The upper reaches of the Yangtze River Bridge, can also be seen in good weather, but today has entered a "stealth" mode. At Hankou Riverside Parks usually have many members of the public to exercise in the morning, today, it's hard to see a figure, still some smell of dust in the air.

To should fog haze, Wuhan currently is focus carried out six items work: first is strengthened site and road Yang dust of pollution of governance, on construction site, some focus area, implementation dust dust of measures, increased on Muck transport of supervision and management; second is increased on industrial enterprise air pollution real of emissions of regulatory; third is strict check open-air burning garbage or straw, violations; IV is law increased on yellow tagged car of law enforcement efforts, and on risk black smoke of motor vehicle of investigation efforts Last is pay close attention to changing weather conditions, to prepare more artificial rainfall; the sixth is to strengthen air quality monitoring, emergency response preparedness for heavy pollution days.

According to the latest weather forecasts, tomorrow, the day after tomorrow, Wuhan will have a precipitation process, artificial precipitation operations personnel of the city has entered the standby phase, will pay close attention to developments in the weather, as long as the weather permits, will seize the opportunity to enhancement to dust.

Weather forecasts also showed that until this morning, condition rating of four levels of air pollution in Wuhan, is not conducive to dilution, diffusion, and eliminating air pollutants. Ambient air quality situation will remain at heavily polluted state. Just 15 to the 16th, there may be a weak cold front reached Wuhan, Wuhan's hopes will dispel the cold fog.
