Human fart, also known as flatulence, typically contains a mixture of gases. The main components of human fart are:
- Nitrogen (N2) – 50-60%
- Oxygen (O2) – 10-20%
- Carbon dioxide (CO2) – 10-30%
- Hydrogen (H2) – 5-15%
- Methane (CH4) – 5-15%
In addition to these main components, human fart may also contain smaller amounts of other gases, such as:
- Hydrogen sulfide (H2S) – responsible for the characteristic odor
- Methyl mercaptan (CH3SH) – contributes to the odor
- Dimethyl sulfide (CH3SCH3) – contributes to the odor
- Ammonia (NH3) – small amounts
- Other volatile organic compounds (VOCs) – small amounts
It’s worth noting that the composition of human fart can vary depending on factors such as:
- Diet
- Gut health
- Individual differences in metabolism
- Presence of certain medical conditions
On average, a human fart contains around 10-20 different gases. However, the exact composition can vary widely from person to person.
