Water pollution is not directly connected to oxygenation levels, however, certain types of pollution can result in low oxygen levels. Phosphate runoff leads to excessive growth of algae which then leads to excessive amounts of decaying algae which depletes the water of oxygen. But many types of water pollution have no effect on the amount of oxygen dissolved in the water.

∙ 11y agoCO2 as a gas is less soluble at warmer temperatures. This is why you put pop in the fridge to keep it from going flat (keeping it under pressure helps too, i.e. the cap). Oxygen, however, works the exact opposite. Warm environments that are not enclosed are perfect for solubility.

What can decrease the amount of dissolved oxygen in water?
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.
How does algae bloom affect dissolved oxygen?
Nutrients remove oxygen from water either by direct oxidation or through being consumed by plants or animals (bacteria). The potential for oxygen removal is measured by: BOD (biochemical oxygen demand) measures the amount of oxygen that bacteria can remove, COD (chemical oxygen demand) measures how much oxygen can be removed by chemical processes, and TOD (Total Oxygen Demand) is the total of all oxygen removed biochemically and chemically. Generally, colder water can hold more dissolved oxygen than warmer water. If you make a rough nomograph and plot the same amount of dissolved oxygen for a cold and warm temperature, you will see that the cold water is less saturated (can hold more oxygen) than the more saturated warm water. Nutrients effect oxygen levels indirectly in a process called eutrophication. If the nutrient happens to be a limiting nutrient (such as phosphate in lakes), then the carrying capacity of the photosynthetic organisms is raised. This allows for a population growth, commonly seen as algal blooms. The population of decomposers is then boosted too, since they feed (decay) on the phytoplankton/algae. As more and more organic material settles to the benthic zone, decomposers increase and need more oxygen for respiration. This results in oxygen depletion in the ecosystem, making life for marine animals such as fish difficult/impossible.
What is the effect of temperature on the amount of oxygen that water a different temperatures can hold?
As a gas, its solubility in water decreases as temperature increases.Boiling water produces oxygen gas bubbles, which means you can get out most of the oxygen dissolved in water by boiling water, thus, for example, a fish can't live in water you boiled.
Air has more capacity to hold water at what?
Air has more capacity to hold water when the air is warmer. The colder the air is, the less water it can hold.
Can hot air hold more or less water than cold air?
Hot air can hold much more water because they are compacted and not spaced out.
how does temperature affect the concentration of dissolved oxygen?
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
Why does metal not rust in boiled water?
Water at high temperature will have less dissolved gases including oxygen.
Some power plants release hot waste water into nearby rivers or streams fish living in these waters sometimes die from lack of oxygen write a hypothesis to explain what has happened to the oxygen?
Because gases dissolved in water is different then solids dissolved in water, warm water holds less dissolved oxygen than cool or cold water Hot water released in rivers or streams lowers the dissolved oxygen concentrations. Since fish also needs oxygen to live, they can't survive because there is not enough dissolved oxygen in the water for them to live off of.
What is the definition of dissolved oxygen?
No, you can't dissolve oxygen in water, even if it's under the ocean. However, hydrogen and oxygen can be generated by passing an electric current through water and collecting the two gases as they bubble off.
How does the temperature of water effect the dissolved oxygen?
Well, dissolved oxygen impacts water quality because if the level of the dissolved oxygen is too low then organisms can die. _________________________________________________________________ That is okay, but I want to what dissolved oxygen tests for. ------ For the water quality are tested: - total oxygen demand (TOD) - biochemical oxygen demand (BOD) - chemical oxygen demand (COD) - sometimes, carbonaceous biochemical oxygen demand (CBOD) For details about the analytical procedures I recommend you to read a book or a collection of analytical methods for water, searching in a library or searching on the Internet.
Why some oxygen dissolved in water?
Like most diatomic gas molecules oxygen will not dissolve very well in water (less than 10 mg/L at STP).
What can decrease the amount of dissolved oxygen in water?
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.
Can you start heating your tank with your goldfish in it?
It's typically not recommended. Goldfish are cold water fish, and are used to the levels of dissolved oxygen in colder waters. Since warmer water holds less dissolved oxygen than cold water, it may negatively impact the health of your goldfish.
Will fish gill's move faster in different temperatures?
Fish will breathe faster in warmer water as there is less capacity to hold dissolved oxygen, thus the fish must pump it's gills faster to get a sufficient ammount.
What do you think is a contributing factor to a fishkill that occurs during summer months that may be traced to temperature effect on solubility of a gas in water?
At high temperature, oxygen is less soluble in water. Fishes need dissolved oxygen in their respiration. A fish kill results when the dissolved oxygen in water is so depleted that the fish cannot survive.
What is the relationship between temperature and dissolved oxygen in an aquatic ecosystem?
The colder the water, the more DO (dissolved oxygen) it can contain.
Why animals living in the water breath faster as compared to land animals?
because there are less amount of dissolved oxygen in water so that aquatic animals breathe more faster in order to get more oxygen.
