Farts SMELL, we get it! For some people it’s worse than others, and sometimes when we “PASS GAS” it can be smelly, and other times not as smelly, so why is that?!
Flatus Emissions, or farts that is, produce (in general terms) two distinct types of gas: methane gas or sulfide gas.
When we think of methane gas, we tend to think of cows and global warming, right? We, as humans, tend to have a significant amount of methane in our flatulence. In fact, it’s interesting to note that the methane gas in farts is indeed flammable.
While methane is indeed flammable - it is not smelly. Most of the methane based gas comes from eating a plant-based diet. Now let's go back to the question of whether humans are contributing to global warming through methane farts. Could this be a possibility? Well, there’s no true research on this right now, we do know that cow burps emit much more methane than human farts.
For anybody looking to obtain funding for a grant, this may be a worthwhile topic to look into.
The other type of “fart gas” is sulfide gas (meaning, the flatus is composed of mainly hydrogen sulfide). This tends to occur when we eat foods that are high in sulfur. This is when farts have that rotten egg smell.
So when you want to know whether you are a methane or sulfur farter, a simple smell test will do the trick.
