Studies that detected the presence of hydrotrioxides in the atmosphere were carried out by Danish and German researchers.
A new class of compounds has been detected in the atmosphere.these are Hydrogen trioxideSuspected of its existence, but without evidence, Impact on human health And it has not yet been studied in the global climate.
Team led by Leibzniz Institute for Tropospheric Research (Tropos), in Germany, Science magazine A study in which he first provided evidence that hydrotrioxide (ROOOH) formation also occurs in atmospheric conditions and records their formation.
Hydrogen trioxide (ROOOH) Gaseous substance It has a group consisting of three consecutive oxygen atoms “O” and a hydrogen atom “H” bonded to the organic part (R).
The atmosphere of the planet Earth is a great driving force for chemical reactions. An example photo: NASA / ViaRawpixel.
In laboratory experiments, they had hydrotrioxide Atmospheric decomposition Of known widely released substances such as isoprene and dimethyl sulfide.
Using quantum chemistry calculations and models, important data for this new class of matter is estimated and estimated as follows: Its useful life ranges from minutes to hoursStable enough to react with other atmospheric compounds.
The bottom layer of the Earth’s atmosphere Large chemical reactor Millions of metric tons of hydrocarbons are converted each year and emitted from forests or anthropogenic sources, eventually Formation of carbon dioxide and water.
“The types of compounds we have discovered are Its structure is unique.. And because they are so oxidative, they are likely to have many effects that we have not yet discovered. ” Henrik Frum Kjærgaard, One of the signatories of the University of Copenhagen. He added that it was necessary. Torsten Berndt “Continue your research to determine the role of hydrotrioxide in health and the environment” at the Tropos Institute.
Torsten Berndt and Frank Stratmann of the Tropos Institute in Germany worked during the investigation to detect new reactive gases in the atmosphere.
In any case, Careguard says these compounds are “They were always there, we didn’t know about themAnd now having evidence of its formation means that we can study its effects more specifically and answer in the following cases: “They turned out to be dangerous.”
team It seems that hydrogen trioxide can penetrate They become small particles in the air known as aerosols, where they form new compounds with new effects.
“It’s easy to imagine the formation of new substances in aerosols. Harmful when inhaled.. But more research is needed to address these potential health effects. “
The experiment was performed via a free flow tube at room temperature.
According to the science team, the importance of the first successful detection of this class of material will become apparent in the coming years. The Tropos Institute was primarily responsible for laboratory surveys conducted at. A tube that flows freely at room temperature Combined with the use of a very sensitive mass spectrometer.
The California Institute of Technology (Caltech) is the stability of hydrogen trioxide University of Copenhagen Quantum chemistry calculations were performed to explain the reaction mechanisms and their temperature and photostability.
