Hong Kong air quality declines

Air quality in Hong Kong has declined considerably in the last four years, with high pollution levels being blamed on vehicle emissions, it has been reported.

According to government figures, there were 1,066 hours of ’very high’ pollution levels during the first half of 2009, representing a sixfold increase since 2005.

Speaking to the South China Morning Post, expert Alexis Lau said the problem is being caused at street level.

"All we need is a lot more and urgent measures to address vehicular pollution to protect public health," he said.

Emissions from factories in southern China are also thought to have contributed to air quality issues in the area in recent years.

In related news, the China Daily reported that authorities in the country are planning to improve air quality in Guangzhou ahead of the 16th Asian Games next year.

It is thought that up to 32 chemical plants may need to close or halt production in order to cut pollution in the area.
