In GT New Horizons, pollution is a chunk-based effect, with each Minecraft chunk having a pollution amount measured in 'gibbl'. All blocks within the same chunk are equally affected by pollution, regardless of the location of the pollution-generating machines within the chunk. If the pollution amount exceeds 500,000 gibbl, players may experience debuffs such as Weakness, Slowness, or Mining Fatigue. Higher levels of pollution can lead to more severe debuffs, including Hunger, Nausea, Poison, or Blindness. Players can mitigate pollution by installing higher-tier muffler hatches and using pollution scrubbers or multiblock air filters. Additionally, pollution naturally dissipates over time. While some players view pollution as a negative mechanic, others suggest it can incentivise efficient base building and the use of advanced machinery.

Pollution removal with Electric Air Filter (EAF) multiblock
In GT New Horizons, pollution is a major concern, as it can cause negative effects such as debuffs for players if left unchecked. The Electric Air Filter (EAF) multiblock machine is an effective solution for removing pollution within a specified range.
The EAF multiblock comes in three tiers: Tier 1 (T1) operates at LV, Tier 2 (T2) at HV, and Tier 3 (T3) at IV. Each tier offers a larger working range and faster pollution removal. For example, T1 works on 3x3 chunks, T2 on 5x5, and T3 on 7x7. Additionally, the higher tiers consume significantly more power, with T1 consuming 30 EU/t, T2 consuming 480 EU/t, and T3 consuming 7,680 EU/t. It is important to note that insufficient power will cause the EAF to shut down.
The EAF requires a Turbine rotor, with efficiency being the key factor. The machine can accommodate up to eight muffler hatches, and each additional hatch increases its pollution-cleaning efficiency. However, the effective tier of the muffler hatch is limited by the power tier used to operate the EAF. For instance, if the EAF operates on HV power, even IV mufflers will only function as HV. The EAF also utilizes Absorption Filters, which should be placed in the input bus, and dirty filters will be outputted to the output bus.
The amount of pollution removed per second by the EAF depends on several factors, including the number and tier of muffler hatches, the tier of the energy hatch powering the multiblock, and any maintenance issues. To ensure optimal performance, it is recommended to have eight muffler hatches of the highest tier allowed by the energy hatch and a 100% efficient turbine, with no maintenance issues.
While the EAF is an effective solution, there have been discussions about rebalancing its performance. Suggestions include adjusting the multiplier based on the tier of the filter, capping the allowed tier of energy/muffler hatches based on the EAF tier, and changing the removal mechanism to incentivize the use of higher-tier EAFs.

Debuffs from high pollution levels
In GT New Horizons, machines in the GregTech mod generate pollution while running. If left unchecked, pollution can cause various negative effects, including debuffs. The level and duration of the debuffs depend on the amount of pollution.
If the pollution amount in a chunk exceeds 500,000 gibbl, all living entities in the chunk, including players, may experience debuffs such as Weakness, Slowness, or Mining Fatigue. The level of these debuffs is calculated using the formula: Level = 1 + (pollution / 400,000), rounded down. The duration is calculated as: Duration = (pollution / 1,000) ticks, up to a maximum of 1,000 ticks (50 seconds). These debuffs can be removed through normal methods such as drinking milk, and players wearing hazmat protection armour are not affected.
As pollution levels continue to rise, the debuffs become more severe. At pollution levels exceeding 750,000 gibbl, entities may experience Hunger, Nausea, Poison, or Blindness. At 1,000,000 gibbl, plant life in the chunk may be destroyed, and at 2,000,000 gibbl, blocks under the exposed sky can undergo additional changes, such as stone converting to cobblestone.
Players can mitigate these effects by reducing the amount of pollution generated by machines. This can be achieved by installing higher-tier muffler hatches, such as the Advanced Muffler Hatch, which significantly reduces pollution output. Additionally, pollution can be removed from the environment using machines like the Pollution Scrubber or multiblock Air Filters, such as the Electric Air Filter (EAF) multiblock.

Advanced Muffler Hatches to reduce pollution
In GT New Horizons, pollution is a chunk-based effect, with each Minecraft chunk having a pollution amount measured in units called 'gibbl'. All blocks within the same chunk are affected by pollution equally, regardless of where the pollution-generating machines are located. If the pollution level exceeds 500,000 gibbl, players and other living entities in the chunk may experience debuffs such as Weakness, Slowness, or Mining Fatigue. As pollution levels continue to rise, more severe debuffs can occur, including Hunger, Nausea, Poison, and Blindness.
To mitigate pollution, players can employ Advanced Muffler Hatches, which are an effective way to reduce pollution from machines. Advanced Muffler Hatches are more challenging to craft than basic mufflers, but they offer a significant reduction in pollution output. The pollution output is calculated as 0.64^(Hatch tier - 1) of the base amount, with LV being tier 1. To activate an advanced muffler hatch, players need to insert either a Tier 1 or Tier 2 Air Filter into its UI. These filters have a limited durability, with Tier 1 filters offering 50 durability and Tier 2 filters providing 2,500 durability. It's important to note that the durability of the filter is consumed each time pollution is ejected from the machine, so machines with higher pollution generation will deplete the filter faster.
When using Advanced Muffler Hatches, it's crucial to ensure that there are three blocks of empty air in front of them, as they require more space than basic mufflers. Additionally, if the filter in an advanced muffler breaks, its efficiency decreases to that of a basic muffler of the same tier. While Advanced Muffler Hatches are an effective solution, they may not be suitable for all machines. For instance, the Advanced Muffler Hatches used by some players in the HV tier consume carbon Air Filters, which can be used up after 50 uses, requiring manual restock.
To further reduce pollution, players can combine Advanced Muffler Hatches with multiblock Air Filters, which can cover a 3x3 chunk area. By placing eight muffler hatches within the multiblock Air Filter structure, players can effectively manage pollution levels. Additionally, a transvector interface block bound to the muffler hatch has been suggested as a solution to automate the restock of air filters.
While Advanced Muffler Hatches are a viable option for pollution reduction, players should also be aware of other methods to address pollution. Upgrading to higher-tier muffler hatches, such as HV or UHV, can significantly reduce pollution levels, with UHV mufflers generating no pollution at all. Additionally, pollution scrubbers and multiblock Air Filters can be employed to remove pollution from the environment. For those seeking a comprehensive solution, the Electric Air Filter (EAF) multiblock, which comes in three tiers (T1, T2, and T3), offers increased working range and pollution removal speed. However, it's important to ensure sufficient power is provided to the EAF to avoid shutdown.

Hazmat suits to protect from pollution
Hazmat suits are an essential form of personal protective equipment (PPE) when it comes to safeguarding oneself from the harmful effects of pollution in GT New Horizons. The game emphasizes the importance of "getting hazmat protection gear asap and then ignor [ing] pollution."
In the context of GT New Horizons, pollution is generated by machines, and if the pollution level in a chunk exceeds certain thresholds, players and other living entities can experience detrimental debuffs such as weakness, slowness, mining fatigue, hunger, nausea, poison, or blindness. These debuffs can be avoided by wearing a full set of armor that provides hazmat protection.
In real-world applications, hazmat suits serve a similar purpose of protecting individuals from hazardous materials, substances, and environments. They are designed to prevent direct contact with or inhalation of harmful agents, including chemicals, biological agents, radioactive materials, and toxic gases. Hazmat suits are often combined with self-contained breathing apparatus (SCBA) to ensure a supply of breathable air, as working in a hazmat suit can be strenuous and poorly ventilated.
The effectiveness of hazmat suits varies, and they are classified into different levels based on the degree of protection they offer. For example, Level A suits in the United States offer the highest level of protection against vapors, gases, mists, and particles, while Level C suits, such as the MIRA Safety HAZ-SUIT, provide full-body protection from deadly chemical, radioactive, and toxic agents. The MIRA Safety HAZ-SUIT is designed to be durable, flexible, and compatible with various respiratory protection options, making it a versatile solution for a range of hazardous scenarios.
In summary, whether in the context of GT New Horizons or real-world applications, hazmat suits play a critical role in protecting individuals from the harmful effects of pollution and hazardous materials. By providing full-body protection and ensuring access to breathable air, hazmat suits enable individuals to operate safely in contaminated environments.

Negative effects of pollution on plants and blocks
In GT New Horizons, pollution can have detrimental effects on plants and blocks. If the pollution amount in a chunk exceeds 1,000,000 gibbl, plant life may be destroyed. Vanilla Minecraft plants such as wheat, carrots, pumpkins, sugar canes, vines, and flowers are broken and drop as items. Grass and seedlings are converted into dead bushes, while mossy cobblestone turns into regular cobblestone. Dirt and cultivated land are transformed into sand, which can break crops.
Pollution levels above 2,000,000 gibbl during rainfall can cause additional changes to blocks exposed to the open sky. Stone is converted into cobblestone, cobblestone into gravel, and gravel into sand. These effects become more severe as pollution levels increase, causing significant damage to the environment.
Players can mitigate these negative impacts by reducing the pollution produced by machines. This can be achieved by installing higher-tier muffler hatches, which decrease the amount of pollution generated. Advanced muffler hatches, for instance, can significantly reduce pollution output. Additionally, machines like the Electric Air Filter (EAF) multiblock are designed to remove pollution from the environment.
It is worth noting that pollution does not affect the growth of IC2 crops or other plants. However, excessive pollution can turn farmland into sand, indirectly harming crops.
While pollution can have adverse effects, it is important to recognize that it dissipates over time. Additionally, trees can play a role in reducing pollution levels, and certain machines can help address pollution more effectively.
