Air pollution levels in Hong Kong reached a record high earlier this week, it has been reported.
According to the Times, smog and dust caused by a sandstorm in northern China have reduced visibility levels and created clouds of noxious air above the city yesterday (March 22nd).
"Readings around the city were pushed over the top of the 500-point air pollution index and into previously uncharted territory. The previous highest recorded pollution level was 202, in July 2008," the publication noted.
Residents with respiratory conditions and heart problems have been urged to avoid venturing outside. However, doctors have warned that even this may not offer total protection.
Meanwhile, the BBC reported last week that 200 companies known as the Clean Air Network have signed a petition in Hong Kong calling on the government to take action and improve air quality.
The group claims that pollution causes around three deaths per day in the city.
