Hong Kong: Hong Kong’s environmental protection department on Tuesday issued a “very high” pollution warning as the city’s air quality continues to remain poor, the media reported.
The department’s air monitoring stations reported readings of “very high” in the Air Quality Health Index, Channel News Asia reported.
This is the second highest pollution reading, and the general public, especially the elderly and children, were advised to reduce their outdoor activities.
According to the department, the poor reading is the result of a continental air-stream bringing in a higher concentration of pollutants, while increased sunshine also raised photochemical activity. Light winds are doing little to disperse the ozone and nitrogen dioxide.
The pollution is expected to remain in the city until Thursday or Friday, when light showers should roll in from the South China Sea.
Earlier this month, Hong Kong issued “very high” pollution warning when Typhoon Soudelor brought in a mass of high pressure over the city.
