Question

This is regarding several different ways that water can be polluted, including inorganic pollutants such as acids or heavy metals, organic pollutants such as pesticides, pharmaceuticals and hormones and infectious agents that might come from animal or human wastes. We also consider what is cultural eutrophication, a process by which fresh or salt water can be overloaded with nutrients and harmed as a result.

Regarding Protecting Our Nation’s Water and Water Pollution, Open Google Earth and in the search box enter: Bohai Bay, Tianjin,China. Click Search. Zoom out to locate the key rivers entering the bay, then follow them upstream, zooming in to explore the area.

Zoom to the Bohai Bay area itself. What evidence of algae growth in the bay can you see showing as color differences in the water? Where is similar evidence seen elsewhere along the coast?

Explanation / Answer

Answer:

The following rivers which enters into the Bohai bay;

1: Luanhe river

2: Chaobai new river

3: Duliujian river

4: North paishui river

5: Haihe river.

As we can see the area of Tianjin which are captured by the human activities such as industrial zones, shops, buildings, hospitals etc. And the above rivers enters in to the bay after crossing the whole area, means loaded with all the organic and inrganic stuff which are released by these human activities. Therefore, the coast is covered by algae as the green color is extended along the coast. And this color difference can be observe along all the coast line of Bohai Bay of Tianjin area due to above reason.
