Shenzhen will make public the number of hazy days each month starting from February and will introduce a mechanism to warn the public in advance if the haze has reduced visibility to below 3 kilometers.
In January, Shenzhen recorded 18 hazy days.
Previously, the city reported the number of hazy days annually at its year-end report.
The monthly report could inform residents of the weather conditions, help the relevant authorities to monitor and investigate the cause of haze, and thus provide information to decision-makers to contain air pollution,” Mao Xia, director of the city’s meteorological observatory, said at a news conference Tuesday.
Shenzhen could become the first city in the Pearl River Delta region to release PM 2.5 data daily, Mao said, without giving details. Particles less than 2.5 micrometers in diameter, or PM 2.5, reduce visibility and cause the air to appear hazy when levels are elevated.
According to a release in January, the average amount of PM2.5 in Shenzhen in 2010 was 37 micrograms per cubic meter, which is lower than other cities, according to Li Shuisheng, vice chief of the city’s environmental watchdog.
To relieve the pollution caused by vehicle emissions, Li said Shenzhen will promote national IV standard diesel oil before the end of the year and ban yellow-label vehicles citywide by 2015. The city now bans yellow-label vehicles on 17 roads and CBDs.
Shenzhen will start to charge dust fees to reduce pollution at construction sites in June.
