Background
The Pearl River Delta region, as part of the South China Sea, has experienced tremendous growth in the past few decades. The increased social and economic activities have brought about serious deterioration of the water quality due to pollutants discharged into the Pearl River estuary system. The Hong Kong Jockey Club has awarded HK$18,000,000 study under the Chief Executive Community project for CCAR to conduct scientific investigation of pollution in the Pearl River Estuary. |

Objective
The objective of the Pearl River Estuary Pollution Project (PREPP) is to use a combination of traditional and new technologies to gain a solid understanding of the status of selected toxic pollutants, sediment, phytoplankton and nutrient levels in the Pearl River Estuary. Given the dramatic growth of industry and population in the area, this information is urgently needed to ensure that government pollution monitoring and control strategies are in line with the most serious threats to ecology and human health. |
Input
|
Output Data from both the shore-based and the shipboard measurement are integrated with the secondary data from public and private sectors for incorporation to our real-time Geographical Information System (GIS). The water quality situation display provides real-time, tactical and strategic information on the environmental quality of the waters in the Pearl River Estuary. It gives both the spatial and temporal variations of the measurements. These results can help us understand when harmful algal blooms will occur. We provide scientifically based biological alerts. |
Field Programs Field observation is an important component of the PREPP. Both shore- based and cruise measurements provide real-time data on the Pearl River Estuary.
