The worst job in the world: Appraising odor of toilet

(Such things as eliminating bad breath or smelling body odor cannot be worse and more strange than evaluating the smell of toilet.

If you think your career is bad, wait until you hear this job: the toilet smoker. Although the smell of the toilet was obviously horrible, it was not clear how to fight the elves.

The first step in developing the anti-odor technology is to determine which chemicals cause the odor . Scientists use a combination of chemical methods with human analysis to determine the odor-causing component of toilets in Africa and India (there is a lot of sulfur here). So the next time you feel depressed, think about scientists who sacrificed their noses for the benefit of people using toilets everywhere.

Qualitative and quantitative analysis of volatile components in toilets.

'More than 2.5 million people go to the bathroom outdoors. The increasing commitment of private and public organizations to address this situation is driving research and the development of new technologies towards toilets and latrines. Although scientists have considered key aspects when designing new technologies for developing countries, the basic ways to prevent odors from human waste are always ignored.

With the aim of contributing to the adoption of a globally accepted solution, scientists studied the chemical composition of the stench from toilet samples in Africa and India.

Toilets in 4 countries are evaluated by smell and quantitative and qualitative properties of scents are described by 3 analytical techniques . Sulfur compounds include: H ₂ S, methyl mecaptan CH ₃ SH and dimethyl-mono- (di; tri) sulfide are indispensable components in waste water as well as in the smell of toilet under anaerobic conditions .

In aerobic conditions, for example in Nairobi, a city in Kenya, Africa, paracresol and indole reaches concentrations of 89 and 65mg / g. This work represents the first qualitative and quantitative studies of volatile compounds sampled from seven sanitary pits in different geographical, technical and economic areas up to three samples. discharged from India and a toilet model system '.
