Scientists from Fujita Health University claim that limiting the concentration of ozone gas in the atmosphere to a certain degree has a powerful effect on neutralizing coronavirus particles.

The finding could be a particularly promising way for hospitals to disinfect their testing centers more effectively, the scientists told on Wednesday, Reuters reports.

To conduct the experiment scientists reduced the concentration of ozone from 0.5 to 0.1 parts per million, which can kill the viruses but is harmless for humans, they said in a news conference.

A sample of coronavirus was put in a chamber which modified using an artificial ozone generator. After 10-hours it was found, the potency of the coronavirus was declined by 90-percent.

Lead researcher Takayuki Murata said the method was particularly effective in high humidity conditions.

“Transmission of the novel coronavirus may be reduced by continuous low concentration ozone treatment, even in an environment where people are present using this kind of system.”

Is Ozone really effective?

Ozone, also known as  O3 by the chemical formulae, is a pale blue gas that smells distinctively pungent. The gas is naturally formed where the Sun’s ultraviolet rays touch the electrical discharges of the Earth’s atmosphere. 

Ozone has been proven to neutralize many pathogens but at the cost of posing potential health hazards to humans.

The United States Environmental Protection Agency (EPA) has earlier said, there is “evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odor-causing chemicals” or “viruses, bacteria, mold, or other biological pollutants”.

At 1-6 parts per million, ozone concentration is harmful to human health but can kill coronavirus, earlier studies show. But this particular trial claims 0.5 to 0.1 parts per million is also effective in neutralizing the virus if sustained for 10-hours.
