Beijing [China], Mar 26 (ANI): China has issued its third major "orange alert" this year, as pollution levels rose up after capital Beijing was named as the country's top city for reducing air pollution last week.
"The central part of the Beijing-Tianjin-Hebei region is expected to see medium to heavy pollution over the three days," it added.
China has a four-tier colour coded pollution warning system, where red is the most severe, followed by orange, yellow and blue respectively.
In December last year, the Chinese government launched a "massive battleplan" against smog during the winter months, during which pollution usually worsens due to heating.
According to the plan, it included switching households and industries to natural gas from coal for their heating and other needs, as well as compulsory cuts in steel production in the surrounding areas.
The Chinese capital, particularly, has suffered serious air pollution levels for the last many years, produced by exhaust emissions and coal burning from factories in the surrounding regions, accompanied by local construction dust. (ANI)
