What You'll Learn
Sources: Slime, dirt, water, Morbs, and geysers
Polluted oxygen can be obtained from various sources in the game Oxygen Not Included. Here are some methods for acquiring polluted oxygen, focusing on the sources you mentioned: slime, dirt, water, Morbs, and geysers.
Slime
Slime can be a source of polluted oxygen, especially when it is contaminated with slimelung germs. When a slimelung-infested slime tile is dug out, the slime can begin to off-gas polluted oxygen. However, it is important to note that not all slime tiles are infected with slimelung, and the germs do not naturally spread between natural tiles. To contain the spread of slimelung, players can submerge slimelung-infested slime tiles in liquid to prevent them from off-gassing polluted oxygen.
Dirt
Polluted dirt, similar to polluted water, emits polluted oxygen. It will stop emitting polluted oxygen when the pressure above it reaches 1.8 kg.
Water
Polluted water is a common source of polluted oxygen. It is the most common naturally occurring liquid on most asteroids, especially in the Swamp Biome. Polluted water emits polluted oxygen, even in a vacuum. However, the emission rate is inconsistent due to the low probability of conversion. To maximise production, it is recommended to spread out polluted water tiles rather than stacking them.
Morbs
Morbs can be used to obtain polluted oxygen. A user on the r/Oxygennotincluded subreddit calculated that using 810 morbs could potentially produce 162 kg of polluted oxygen every 12 seconds. However, this assumes ideal conditions, and the actual output may vary.
Geysers
Geysers can be a source of polluted oxygen, although their presence is not guaranteed. Each biome type can have up to two buried geysers, and there is a 52.78% chance of having at least one geyser directly producing oxygen. Geysers can be analysed by a Duplicant with the Field Research skill to determine their activity and dormancy durations. The output of geysers can be boosted by Geotuner stations, but this comes at a resource cost.

Risks: Slimelung, food poisoning, Yucky Lungs debuff, food rotting
Allowing Duplicants to breathe polluted oxygen can save costs on deodorizers, but it comes with significant health and operational risks. The polluted oxygen can cause the Yucky Lungs debuff, increasing air consumption by 30%. This higher rate of consumption can lead to a faster depletion of oxygen reserves, affecting the overall sustainability of the oxygen supply. Additionally, the debuff itself can be uncomfortable and impact the productivity and well-being of the Duplicants.
The primary health risk associated with polluted oxygen is the rapid spread of Slimelung, a dangerous germ that multiplies quickly in polluted oxygen and slime. Slimelung is typically found in the Swamp Biome and can infect large clouds of polluted oxygen. Inhalation of contaminated air or contact with heavily contaminated surfaces can overwhelm a duplicant's immune system, leading to lethal consequences if left untreated. Slimelung spreads aggressively and can infect nearby gases and solid tiles, making it a serious threat to the health and safety of the colony.
Another concern with polluted oxygen is the increased risk of food poisoning. While not a direct consequence of polluted oxygen, the presence of food in an oxygen-rich environment can provide an ideal condition for bacteria and contaminants to thrive, leading to food spoilage and potential foodborne illnesses. Proper food storage and handling practices become even more critical in such conditions to prevent food poisoning outbreaks.
The combination of polluted oxygen and high humidity can also create an optimal environment for mould and mildew growth. While this may not directly cause food poisoning, it can contaminate surfaces and food, increasing the risk of foodborne illnesses if hygiene standards are not rigorously maintained. Regular cleaning and disinfection are essential to mitigate this risk. Additionally, ensuring that food is stored in airtight containers and that the surrounding environment is well-ventilated can help prevent mould growth and reduce the chances of food contamination.
To mitigate these risks, it is crucial to prioritize air filtration and purification techniques. Implementing deodorizers and filtration systems can help remove pollutants and contaminants from the air, reducing the chances of Slimelung proliferation and improving the overall air quality. Additionally, promoting good hygiene practices, such as regular handwashing and sanitization, can minimize the spread of germs and reduce the risk of food poisoning. Proper food storage, handling, and preparation techniques are also essential to prevent food contamination and spoilage.

Cleaning: Sublimation, cooling/reheating, deodorizers, Pufts
Polluted Oxygen can be cleaned through a variety of methods, including sublimation, cooling and reheating, deodorizers, and Pufts. Sublimation involves using a Sublimation Station to convert Polluted Dirt into Polluted Oxygen. This process produces 660g/s of Polluted Oxygen from 1000g/s of Polluted Dirt. Another method is to cool Polluted Oxygen to its condensation point, converting it into Liquid Oxygen, and then reheating it. This can be achieved using Thermo Regulators.
Deodorizers are an effective and low-cost way to convert Polluted Oxygen (PO2) into Oxygen (O2). Proper airflow and positioning of deodorizers are crucial for optimal results. Additionally, ensuring the proper disposal and storage of polluted water and dirt is essential to reducing Polluted Oxygen. Pufts, particularly wild ones, can also help sustain and manage Polluted Oxygen levels.
It is important to identify the source of Polluted Oxygen to effectively manage and reduce it. Sources can include slime, polluted dirt, and polluted water. Polluted Water emits Polluted Oxygen into the air in environments with <1800g of air pressure, spreading any germs present. Unbottled Polluted Water will emit Polluted Oxygen under the same conditions, while bottled Polluted Water will spread germs into the air. Morbs produce Polluted Oxygen in environments with <1000g of air pressure and continue to release it upon death. Additionally, Polluted Oxygen can be found naturally in the Swamp Biome and emitted by certain geysers, such as Hot and Infectious Polluted Oxygen Vents.

Supply: Rocket missions, Sublimation Station, Swamp Biome
Polluted Oxygen is a dirty, unfiltered air resource that is breathable and works similarly to Oxygen, allowing Duplicants to survive. However, it is important to note that breathing too much Polluted Oxygen causes the Yucky Lungs debuff, increasing the air consumption rate and causing coughing. It also acts as the primary vector for transmitting Slimelung germs and can easily spread Food Poisoning germs. Polluted Oxygen can be found naturally in the Swamp Biome and is emitted by Slime, Polluted Dirt, and bottled or unbottled Polluted Water in environments with _
One way to supply Polluted Oxygen is through rocket missions to renewable Space POIs. In the Oxygen-Rich Asteroid Field, Polluted Oxygen can be harvested at a rate of 30-100 kg per cycle, and in the Organic Mass Field, the rate is 54-162 kg per cycle. Additionally, the Sublimation Station can be used to turn 1000g/s of Polluted Dirt into 660g/s of Polluted Oxygen. Polluted Oxygen can also be converted to Liquid Oxygen by cooling it to its condensation point and then reheating it.
The Swamp Biome naturally contains Polluted Oxygen and is a reliable source. Polluted Water, which is common in the Swamp Biome, emits Polluted Oxygen. Polluted Ice in Frozen Biomes will also melt and turn into Polluted Water, contributing to the Polluted Oxygen supply.
While Polluted Oxygen can be a useful resource, it is important to manage it carefully due to its negative effects on health and food preservation. Deodorizers can be used to convert Polluted Oxygen into Oxygen, and proper disposal and storage of Polluted Water and Dirt are essential to prevent the spread of germs.

Prevention: Proper disposal, storing polluted water, base layout
Polluted water is the most common naturally occurring liquid on most asteroids, and it fills caves with polluted oxygen. It can be created by various sources, including Duplicants not reaching a toilet in time, stress-vomiting, lavatories, showers, wash basins, sinks, and as a by-product of certain amenities and machines. While polluted water can be dropped into clean water tanks without contaminating the clean water, if the polluted liquid contains germs, the clean water will also become contaminated. Small amounts of polluted water, less than 150 kg, can be mopped up.
To prevent the negative effects of polluted water, proper disposal and storage techniques are essential. One method is to use a water sieve to remove the pollution, converting it back into clean water. This can be combined with a carbon skimmer, which captures carbon dioxide and produces polluted water as a by-product. By connecting the water sieve to the carbon skimmer, a loop can be created to manage both carbon dioxide and polluted water effectively. Additionally, deodorizers can be placed at the entrance of polluted oxygen (P02) tanks to convert it back into clean oxygen and clay, although this will use up sand.
When storing polluted water, it is important to prevent off-gassing, which can be done by placing bottles of clean water on top or by over-pressurizing the storage area. Storing polluted water in two separate tanks, one for germy and one for non-infected water, is also recommended. The germy tank can be utilized as a heat dump with aquatuners, and deodorizers can be placed above to ensure the production of clean oxygen.
In terms of base layout, it is suggested to place the carbon skimmer at the bottom of your base or further down your ladder network, eventually reaching the oil biome. This will help manage carbon dioxide buildup and facilitate access to other biomes. Additionally, when dealing with slimelung, which can be released from digging, storing the slime in a storage bin in an ice biome will effectively kill the germs.
