AIR QUALITY REPORT FOR OCTOBER

THE ENVIRONMENTAL PROTECTION DEPARTMENT

RELEASED AIR QUALITY INFORMATION FOR OCTOBER.

TODAY (FRIDAY)

A SPOKESMAN FOR THE DEPARTMENT SAID THE ANNOUNCEMENT WAS ΤΟ KEEP THE PUBLIC INFORMED OF THE AIR QUALITY LEVELS IN THE TERRITORY AND TO EXPLAIN THE MEASUREMENTS.

THE INFORMATION NORMALLY CONTAINS MONITORING RESULTS OBTAINED AT ITS MONG KOK, CENTRAL/WESTERN AND KWAI CHUNG MONITORING STATIONS.

THE LOCATIONS ARE TYPICAL OF THE FOLLOWING THREE OF THE

IMPORTANT LAND TYPES FOUND IN THE TERRITORY:

* LOCATIONS CLOSE TO ROAD TRAFFIC IN BUILT-UP URBAN DISTRICTS,

* COMBINED COMMERCIAL AND RESIDENTIAL DISTRICTS, AND

* DISTRICTS CLOSE TO INDUSTRIAL AREAS.

THE REPORTED AIR POLLUTANTS INCLUDE SULPHUR DIOXIDE (SO2), NITROGEN DIOXIDE (NO2), RESPIRABLE SUSPENDED PARTICULATES (RSP) AND TOTAL SUSPENDED PARTICULATES (TSP).

THE GASEOUS POLLUTANTS ARE MONITORED CONTINUOUSLY WHILE PARTICLE SAMPLES ARE COLLECTED FOR 24 HOURS, ONCE EVERY SIX DAYS.

DURING OCTOBER, LEVELS OF TSP WERE HIGHEST ON THE STREET LEVEL SITE AT MONG KOK.

ON OCTOBER 7, CONCENTRATIONS ALMOST REACHED THE 24-HOUR AIR QUALITY OBJECTIVE VALUE OF 260 UG/CUBIC METER.

THE HIGH TSP LEvels on THAT DAY ARE THOUGHT TO HAVE ARISEN BECAUSE THERE HAD BEEN NO RAIN FOR FIVE DAYS AND THE RELATIVE HUMIDITY WAS LOW.

VERY SIMILAR CONDITIONS OCCURRED ON OCTOBER 31, AND THESE ALSO LED TO HIGH TSP LEVELS.
