When dissolved oxygen falls below 8%, aquatic organisms may experience stress or die due to oxygen deprivation. This can disrupt the ecosystem balance, leading to fish kills and other negative impacts on the aquatic habitat. Monitoring and maintaining appropriate levels of dissolved oxygen is crucial for the health of aquatic organisms.

What is the percentage of dissolve oxygen pond?
The ideal percentage of dissolved oxygen in a pond for fish and aquatic organisms is typically between 5-8 mg/L, which is equivalent to roughly 70-120% saturation. Levels below 2 mg/L can be stressful for fish, while above 12 mg/L can cause gas bubble disease in some species. Testing and monitoring dissolved oxygen levels regularly is important for maintaining a healthy pond ecosystem.
What percentage of oxygen for fire?
Oxygen comprises about 21% of the air we breathe. For combustion to occur, the oxygen level needs to be around 16% or higher. If the percentage drops below that, a fire will be deprived of oxygen and will not be able to sustain itself.
What is the dissolved oxygen level of distilled water?
Distilled water typically has very low levels of dissolved oxygen due to the absence of minerals and other gases. The dissolved oxygen level can vary depending on exposure to air and temperature, but it is generally low compared to other types of water.
What is a dangerous level of dissolved oxygen?
A dangerous level of dissolved oxygen in water is below 4-5 mg/L for most aquatic species. Low levels can stress or kill aquatic organisms, disrupt the ecosystem balance, and indicate poor water quality.
What percentage of oxygen is needed for a fire?
A fire needs approximately 16% oxygen in the air to sustain combustion. This is known as the oxygen concentration level for combustion. If the oxygen level drops below this threshold, the fire will be deprived of oxygen and will be extinguished.

A dangerous level of dissolved oxygen in water is below 4-5 mg/L for most aquatic species. Low levels can stress or kill aquatic organisms, disrupt the ecosystem balance, and indicate poor water quality.
How do you find the dissolved oxygen in water?
Applying methods of analytical chemistry; search the produres in manuals of water analysis (as indicated in the link below).
What is the percentage of oxygen in condensate?
The percentage of oxygen in condensate can vary depending on the specific source of the condensate. In general, condensate often contains very low levels of oxygen, typically below 1%. This is because oxygen is not a major component of the vapor that condenses into liquid form.
What percentage of oxygen is needed for a fire?
A fire needs approximately 16% oxygen in the air to sustain combustion. This is known as the oxygen concentration level for combustion. If the oxygen level drops below this threshold, the fire will be deprived of oxygen and will be extinguished.
What percentage of oxygen is required to sustain a fire?
Around 16% oxygen is required to sustain a fire. This level is often referred to as the "minimum oxygen concentration for combustion." Fires can be extinguished by reducing the oxygen level below this threshold.
Why do pollutants affect the amount of dissolved oxygen in water?
Some people get lazy and refuse to wash they re boat upon going into different waters and bring in invasive species which lower the oxygen levels. The worst is algae with uses the dissolved oxygen in the water to breath and suffocate the fish living below them.
What percentage of oxygen to sustain a fire?
A concentration of oxygen in the air above 16% is sufficient to sustain combustion or a fire. Below 16%, fires will have difficulty burning or may not burn at all.
What happens to the dissolved oxygen as is boiled?
When you boil water, the bubbles that you see in the boiling are the dissolved gases (oxygen) being eliminated from ther water. Hence unboiled water has a lot of dissolved gases. Boiled water has very little dissolved gas. Even below a liquids boiling point, the warmer a liquid becomes the less gas it holds in solution. The oceans of the world hold a lot gas in solution, carbon dioxide being one of them. If the oceans warm up, then some of this carbons dioxide will be eliminated into the atmosphere.
What is the root word of hypoxia?
Hypoxia: Hypo = below, ox = presence of oxygen "Below oxygen" or "below normal oxygen levels" Hypoxia means low tissue oxygen level. Or oxygen levels below normal in the tissues.
