Very
high roadside API forecast for today
The Environmental
Protection Department today (Wednesday) forecast that the
Air Pollution Index (API) later today would reach 70 to 125
for the roadside stations, and 55 to 85 for the general stations.
"When the roadside API exceeds 100 and reaches the 'very
high' band, people with heart or respiratory illnesses should
avoid prolonged stay in roads and streets with heavy traffic,"
Acting Principal Environmental Protection Officer, Mr Yeung
Mo-man, said.
"If
it is necessary to stay in such places, they should reduce
physical exertion as far as possible," he said.
He said
that nitrogen dioxide in vehicle emissions, particularly from
diesel vehicles, was not dispersing sufficiently under the
very still wind conditions. Air pollution at the urban roadside
with very heavy traffic and surrounded by high-rise buildings
has thus escalated and reached the "very high" band.
Members
of the public can check the API readings for different locations
on 2827 8541 or from EPD's website at http://www.info.gov.hk/epd/.
