The capital choked in the worst smog in months on Thursday with weather forecasters warning pollution would continue to plague the city into the weekend, the Beijing Morning Post reported.

The “heavy pollution” was blamed on a trough of low pressure hanging over Beijing.

The air quality index (AQI) improved slightly from nearly 300 on Thursday to 230 on Friday, according the Beijing Municipal Bureau of Environmental Protection.

An AQI reading below 50 is good while anything over 200 is very unhealthy – and a reading of more than 300 is hazardous.

By comparison, the level in Hong Kong on Friday afternoon was 66.

The Beijing authorities warned residents to avoid strenuous outdoor activities and advised that children, the elderly and the sick should remain indoors. Many who did venture outside wore face masks to try and protect themselves.

Visibility remained low as thick smog hung over the city and the sun was obscured behind the pollution on Friday.
