Our marine waters are a valuable natural asset. They support a huge variety of wildlife and function a lot for humans. We need to protect our marine waters to ensure that they are fit for marine life growth and different human uses in a sustainable manner.
Parameter of Water Test – WCZs
According to Water Quality Objectives (WQOs) for marine waters of Hong Kong, Hong Kong is divided into ten water control zones (WCZs), each of which has a set of WQOs applied. The following parameters are required to be monitored in WCZs.
Parameters:
| Aesthetic appearance | Dissolved Oxygen (depth-averaged) | Dissolved Oxygen (bottom) |
| Nutrients | Unionized Ammonia | Total Inorganic Nitrogen |
| Total Inorganic Nitrogen | E. coli | Salinity |
| pH | Temperature | Suspended Solids |
| Toxicants | Chlorophyll-a |
The marine water test plays a crucial role in ensuring the safety and health of both marine life and humans. The parameters that are tested in the marine water test include pH levels, dissolved oxygen, temperature, salinity, and turbidity. These parameters are crucial in determining the quality of water in different marine zones and the potential risks to aquatic life and human health.
The marine water test is conducted regularly to monitor the water quality in different zones and to ensure that the water meets the set WQOs. It is important to note that water quality can be directly affected by natural and human activities such as pollution, waste disposal, and climate change.
Therefore, regular monitoring and testing are essential to ensure the long-term health and sustainability of our marine waters. By conducting marine water tests, we can identify any issues and take necessary actions to mitigate any harmful impact on the environment and the people who rely on it.
