Water Quality in Typhoon Shelters

Pollution in typhoon shelters is reflected in the water quality parameters regularly measured by the Environmental Protection Department (EPD). Figure 1 shows the Dissolved Oxygen (DO) levels in four typhoon shelters in Hong Kong. The Ammonia Nitrogen levels in the typhoon shelters are shown in Figure 2. Further information on the water quality of typhoon shelters is available in the annual report Marine Water Quality in Hong Kong.
