To Secretary of the Environment, Secretary for Home Affairs, Director of Leisure and Cultural Services, Director of Home Affairs,,
Public displays of AQHI would allow individuals to monitor the level of air pollution in their immediate area. Whilst the public displays can’t clean up the air in Hong Kong, they could help individuals better prepare for deteriorating air quality for example carrying a face mask or avoiding the area all together. There is a rising concern for health among the general public, and exercising outdoors has become a norm for those hoping to improve their health, however, are we aware of the risk of exposure to toxic air during exercise? Globally, it is estimated that about a half billion people run on a regular basis, and many of those people are running in cities- like Hong Kong where the air quality is poor. We are encouraged to run for our health, but if the air we are running in is polluted, then we are actually being exposed to health risks. In our modern society, many individuals track AQHI through apps, smart watches and the internet but for a large percentage of the population this isn’t possible and applications are also not specific to an area – just the district. Raising awareness of the deteriorating air quality in Hong Kong is also likely to encourage citizens to lessen their individual impact and make switches to their everyday life.
Public displays would:
- Allow individuals to alter their plans on days when the concentration of pollutants, such as PM2.5 is high, to avoid outdoor sports/activities such as running and take part in indoor sports instead.
- Educate the public about air pollution and make AQHI become a household term – its categories would become widely recognised.
- To bring awareness to Hong Kong’s pollution emergency and reduce potential short term/long term health effects.
In a pollution emergency, public spaces in Hong Kong should display changing AQHI levels
