Air pollution stays high

Roadside air pollution passed the 'very high' mark of 100 yesterday for the fourth time this week.

It reached 101 in Causeway Bay, down from 102 on Thursday.

The Environmental Protection Department was still advising people with heart and lung ailments to reduce activity and avoid busy roads.

However, the outlook for the weekend was brighter, principal environmental protection officer Leung Pak-ming said.

'Hopefully, the wind conditions will improve, helping nitrogen dioxide to disperse,' he said.

Roadside stations in Central and Mongkok recorded readings of 99 and 86 respectively.
