The publication Science Alert called the most disgusting smells in the world, based on recent research. In the list of sources of bad flavors came Uranus, the fruit of the durian, the flower of Rafflesia arnoldii, cheese Vieux Boulogne, the ancient faeces and four-toed anteater Tamandua tetradactyla.

It is known that in the lower layers of the atmosphere of Uranus contains hydrogen sulfide, ammonia, methane and carbon dioxide. According to scientists, although the concentration of ammonia is quite small and can reach one hundred parts per billion, the gas can condense and form smelling of cat urine clouds. Such clusters probably forms hydrogen sulfide, which gives the atmosphere the aroma of rotten eggs.

In 2017, scientists from the German research center of food chemistry have found that the odor of the fruit zibethinus of durian (Durio zibethinus) is formed mainly from two compounds — ethyl-(2S)-2-methylbutanoate and 1-(ethylsulfanyl)ethanthiol. The first ingredient creates the aroma of rotten fruit, and the second is onion smell. The result is a sharp stench, reminiscent of old socks, sewage or rotting meat.

Rafflesia arnoldii is a plant-parasite, which has the largest flowers in the world, which emit a specific and attractive to flies, smell of rotting meat. A similar fragrance is and other plant — Amorphophallus titanum — but it blooms much less frequently than the rafflesia.

Cheese Vieux Boulogne became known as the stinky cheese in the world. Researchers level, Cranfield University (UK) experienced it “electronic nose”, which determined that the aroma was similar to the odor caused by infections of the urinary tract and tuberculosis.

The last place in the list of publications is the ancient excrement, which continues to emit the stench of even a few centuries, and the four-toed anteater, the smell of which can be five to seven times stronger than the smell of skunk.
