Aquatic plants in Shanghai combat water pollution with impressive efficiency.
Eutrophication is a big problem in Shanghai's water. Scientists tested three water plants to see which one is best at removing nutrients. They found that Phragmites australis is the most effective at cleaning the water. Aeration helps the plants work better, especially when the plants are in the sediment. This study shows that a combination of plants and aeration can help manage eutrophication in water.
