Health risk category for Air Quality Health Index is expected to reach "Serious" level
******************************************************************************************
Under the influence of a dusty air stream associated with the northeast monsoon, the level of suspended particulates in background pollutants has been recorded higher than normal since 10pm last night (April 12). With the monsoon moderating gradually, winds in Hong Kong are expected to weaken and unfavorable to pollutant dispersion in the region, leading to increase in pollution levels. It is anticipated that the pollutant level will remain relatively high in the following one or two day(s). The EPD will keep in view the change in air quality, and release update on the latest situation in due course.
With a health risk category in the "Very High" range or above, children, the elderly and persons with existing heart or respiratory illnesses are advised to reduce physical exertion and outdoor activities to a minimum or avoid such activities.
