Evaporation is the most common, syphoniage due to no vent or a block went is another cause or a leaking trap.

A trap can lose its seal in three main ways: first, through evaporation when water in the trap dries up, allowing sewer gases to escape; second, if the trap becomes damaged or cracked, compromising its integrity; and third, when plumbing changes or improper installation create air gaps, disrupting the seal. Regular maintenance and inspection can help prevent these issues.
By cutting it out and installing either a P trap or a running trap as an S trap is notorious for losing its seal
there are 100 inches in a trapseal
A gully trap is a plumbing device designed to prevent foul odors from entering a building through the drainage system. It works by using a curved section of pipe that holds a small amount of water, creating a seal that blocks sewer gases. Wastewater flows into the trap, displacing the water and allowing it to pass through while maintaining the seal. This design effectively keeps the drainage system functional while ensuring that unpleasant smells are kept at bay.

fill it up with clean clear water to replenish the seal
1. the water evaporates out of the trap.2. there is a leak in the trap connections ( only with some traps that have connections in the lower part of the trap.3. a suction force downstream of the trap pulls the water out of the trapTrap seal loss1- Capillary attraction2- Evaporation3- Back pitched4- Negative pressure (back siphonage)5- Positive pressure6- Crack / leak7- Oscillation
Trap seal lost and foul air invading from drainage.
The purpose of the p-trap seal in a plumbing system is to prevent sewer gases and odors from entering the building by creating a water barrier that blocks the passage of these gases.
Just enough to reach the crown weir to prevent fumes from passing through the trap seal

Trap seal loss occurs when you have poor venting and as one fixture drains it creates negative pressure created and it pulls the trap seal (water) from another trap and allows sewer gases to enter the structure
The main difference between a p-trap and an s-trap in plumbing systems is their shape and how they prevent sewer gases from entering the building. A p-trap is shaped like the letter "P" and retains water to create a seal, while an s-trap is shaped like the letter "S" and is prone to siphoning, which can break the seal and allow gases to enter.
A p-trap is designed to hold water and form a seal so the toxic sewer gases cannot enter the house, named for its P shape
Gas in the sewer line is prevented from coming back up into the toilet due to the water seal in the toilet's plumbing trap. This water seal acts as a barrier to block any gases or odors from entering the toilet bowl. Additionally, there are vent pipes in the plumbing system that allow gases to escape through the roof of the building.
A P trap goes thru the wall, an S trap goes thru the floor.
