Environmental Protection Department warns of ‘serious’ air pollution in Hong KongLocal | 23 Jul 2021 4:31 pm
The Air Quality Health Index in Hong Kong may reach the "Serious" level later today, with air pollution levels expected to be higher during the weekend, according to an Environmental Protection Department forecast.
The department said it has recorded higher than normal air pollution levels since this morning.
Under the influence of the outer subsiding air of Tropical Cyclone In-fa, the weather in Hong Kong is mainly fine, very hot and hazy during the day, with light to moderate west to northwesterly winds, which is bringing an airstream with high regional ozone and particulate background pollutant concentrations and is unfavorable for pollutant dispersion.
According to the Hong Kong Observatory, a southwesterly airstream is expected to bring showers to the coast of southern China next week. It is expected that pollution levels will remain higher until then.
With a health risk category in the "Very High" or "Serious" levels, children, the elderly and persons with existing heart or respiratory illnesses are advised to reduce physical exertion and outdoor activities to a minimum or avoid such activities.
The general public are also advised to reduce, or reduce to a minimum, outdoor physical exertion, and to reduce time staying outdoors, especially in areas with heavy traffic.
The public may visit the Centre for Health Protection's website for more information on the health effects of air pollution and relevant health advice.
