What can decrease the amount of dissolved oxygen in water?

Answer 1

Sometimes, water can become overheated, like if it is near a factory or power plant. If the water's temperature increases, then the Dissolved Oxygen (DO) level will decrease, which can cause strain or even death for many fish and marine wildlife.

Answer 2

Various factors can decrease the amount of dissolved oxygen in water, such as high water temperature, pollution from organic waste or chemicals, excessive growth of algae or other aquatic plants, and decomposition of organic matter by bacteria. These factors can lead to oxygen depletion, resulting in harmful conditions for aquatic life.

Answer 3

Low dissolved oxygen has many causes....from prolonged hot temperatures, sewage waste, and chemicals.

Answer 4

There are a great many factors that will affect the level of dissolved oxygen in water. Temperature is one such factor.

Answer 5

If you poor the water slowly when no oxygen can escape into the container make less of a chance of getting oxygen into the water.

Answer 6

Dissolved oxygen in waters (BOD) is very important for the life in waters; also oxygen destroy organic materials from waters.

Answer 7

Temperature and atmospheric pressure

Answer 8

Excessive plant debris.
