Beijing Deep Fog And Haze 6 PM2.5 Stocks Or Meet Again Outbreak

< p > from the beginning of 5 hours, < a href= "http://www.91se91.com/" > Beijing < /a > began to be surrounded by fine particles, PM2.5 concentration reached severe pollution to serious pollution level. On that day, the Central Meteorological Observatory and the Beijing meteorological observatory issued haze yellow warning signals. < /p >
Less than 500 meters in early morning in some parts of Beijing, less than 500 meters in early morning, some visitors to Beijing are ridiculing "Beijing starts smoking mode", enjoying the northern lights in fog. P < /p >
< p > the air quality index released by Beijing environmental monitoring center at 10 hours shows that the main pollutant of Beijing City Environmental Assessment site is PM2.5, the quality index is over 310 micrograms / cubic meter, and the quality level is six level. This is the highest level after the implementation of the new national standard of environmental air quality. Among them, Fengtai garden is 430 micrograms / cubic meter, 431 micrograms / cubic meter of Xizhimen North Street, 427 micrograms / cubic meter of Qianmen East Street, and five grade air quality rating points for suburbs, and a few six level. < /p >
< p > in Beijing air quality real-time release map, the reporter saw a deep red, 35 monitoring points, 32 serious pollution. < /p >

< p > first, the prospect of the environmental monitoring equipment industry will become wider and wider. At present, the gross profit margin of equipment products is relatively high, generally around 50%. The first listed company in the industry is environmental protection (300137, stock bar) and comprehensive monitoring instrument provider, concentrating technology (300203, stock bar), which can provide system monitoring solutions, and will benefit from the vigorous procurement of environmental protection departments. < /p >
< p > secondly, as the main cause of fog and haze such as PM2.5, air pollution control will be strongly supported by policies and funds, especially atmospheric dust removal, desulphurization, out of stock and vehicle exhaust treatment. Large scale thermal power plants and other emissions of dust, nitrogen oxides and other gases can also be called the culprit, and Longyuan Technology (300105, stock bar), Kowloon power, Guodian fresh (002573, stock bar) in the power plant flue gas desulphurization field has its unique advantages, Guodian fresh exclusive dry desulfurization technology, to avoid wet flue gas desulfurization after the formation of nitric acid containing water, causing more serious corrosion. < /p >
< p > Li Lailai, Institute of science and technology of the Ministry of transport, said that vehicle exhaust is also an important factor in the formation of haze. Wei Fu high tech (000581, < a href= "http://www.91se91.com/" > /a ") is mainly used for diesel vehicle and vehicle exhaust aftertreatment system, and product demand will be stimulated by stricter emission standards. < /p >
< p > finally, the air purification equipment will face the market stimulation directly, especially the creation of Yuan Technology (000551, stock bar), which provides industrial enterprises with air purification. < /p >
