We have enjoyed more clean air days in Hong Kong over the past few years. According to the Hedley Environmental Index, the total number of clear days is increased from 109 to 214 between 2016 and 2020. CAN is excited to see the air quality has improved this year but the increasing ground-level ozone pollution becomes an alarming threat to our health.
Pandemic and Air Quality
2020 is the year of pandemic. The global economy, outbound travel and public health systems have been badly affected by the COVID-19 pandemic and lockdown. The coronavirus seriously hit the quality of health care and disrupts our social life worldwide.
We conducted NO2 measurement projects in Central District, Sham Shui Po and West Kowloon over the past year. The findings showed that the NO2 level recorded at the bus stops mainly exceeded the annual safe level recommended by WHO. Commuters and students who queue at the bus stops are at risk as they are exposed to the dangerous level of roadside air pollution daily.
Clean Air Paws Researcher
With the support from Paws Hero, we are happy to team up ten lovely furry friends being our Paws Research Team. The paws researchers help us collecting air data while walking in different routes in their neighborhoods since November. The measurement would raise public awareness of air pollution and its health threats of both human and animals.
But the global pandemic is teaching an expensive lesson in public health. Environmental problems can make us vulnerable to diseases and disasters. If we don’t make any changes to avoid pollution and environmental destruction, there is a huge cost to our economy and our lives.
