An approaching ridge of high pressure from the western North Pacific and an airstream from the Pearl River Delta led to poor air quality that posed a “serious” risk to the health of Hongkongers today.
Netizens have been posting photos and videos of the thick smog that’s been cloaking the city all day, with many blaming the pollution on China.
In the mid-afternoon, the Air Quality Health Index at most general stations reached levels of “very high” risk, ranging from 8 to 10, according to the Environmental Protection Department (EPD). As of 4pm, the general stations at Tsuen Wan, Yuen Long, Tuen Mun and Tung Chung all recorded the highest level of pollution, 10+. It’s worth noting that it is the third time this month that the pollution level in Tung Chung has reached 10+. Meanwhile, stations in Central, Sham Shui Po, Tseung Kwan O, Tap Mun, Causeway Bay and Mong Kok all scored AQHIs of 9.
Most districts recorded lower AQHIs at 6pm, but mainland China’s real-time air quality forecasting system predicted that Hong Kong’s pollution level could climb up again, HK01 reports.
The general public — especially children, the elderly and persons with heart or respiratory illnesses — are advised to avoid physical exertion, outdoor activities and areas with heavy traffic.
The Hong Kong Observatory said the ridge of high pressure would continue to affect southeastern China in the next couple of days and pollution levels in Hong Kong would only be lowered when pollutant dispersion improves. According to the Education Bureau’s school activities guidelines, schools should suspend all physical education classes and all types of outdoor activities and competitions when the Air Quality Health Index poses a “serious” health risk.
