Cold Air from the North to Push Smog Away from the City
The haze and smog that reduced visibility in the city to three kilometers in several areas will be driven away by the incoming cold air and light rain from the north. The PM2.5 level at the Liyuan and Honghu monitoring stations reached around 149 mg per cubic meter and was rated as medium level of pollution and monitoring stations in OCT, Longgang, Xixiang and Nanyou gave reports on light pollution only.
Officials from the environmental administration said that the pollutants in the city that is brought by the dry season will be carried away by the cold air coming in from the north. Local weather for the next few days is expected to be cloudy with light mist or scattered rain showers.
There were 82 hazy days recorded for 2013 which is 5 days more compared to the same period last year. In 2012 of January the city had three more hazy days, April had four more hazy days, October had three while November had five hazy days. This year’s increase of hazy days is due to the weak winds and light rainfall which failed to push or wash away these pollutants.
City data showed that 60 percent of the air pollution in the city is caused mostly by vehicle emissions while other sources such as industrial pollutants, cooking fumes and dust from construction have also contributed to the haze.
