Air quality to deteriorate for next 2 days, forecasters say
Shanghai will enjoy a day of good air quality today after moderate pollution yesterday, but the city will be hit by further pollution tomorrow and Thursday, said the Shanghai Environmental Monitoring Center.
The air quality index was expected to be between 55 and 90 today, indicating good air quality.
Tomorrow, slow wind and accumulation of local air pollutants, mainly nitrogen dioxide, were expected to push the air quality index between 85 and 105, indicating slight pollution.
Weather forecasters expect another cold front to hit the Yangtze River Delta region on Thursday until the weekend, causing slight to moderate pollution in some areas in the region.
Shanghai’s air quality index was forecast to be between 105 and 125, indicating slight pollution from the cold front. The major pollutant was expected to be PM2.5.
“We still need observation to tell whether the next round of pollution will affect Shanghai’s air quality after Thursday,” said the Shanghai Environmental Monitoring Center.
The previous round of air pollution in Shanghai, caused by pollutants carried by a cold front from the north, raised the city’s air quality index to 192, or moderately polluted, at 10am yesterday. PM2.5 was the major pollutant.
