TORONTO – If you thought flushing the toilet couldn’t get any more dangerous, think again.
In a new experiment using a bright green laser and camera equipment, University of Colorado Boulder scientists They were able to visualize airborne particles, invisible to the naked eye, released into the air when an uncovered toilet flush flushes.
Although researchers have known for more than 60 years that these tiny particles are released into the air when cleaned, this study, published in Scientific Reports, is the first to directly visualize and be able to measure how fast the particles travel. .
Here’s the worrying part: These particles can transmit pathogens, including bacteria, viruses, or other disease-causing microorganisms, which is a potential hazard in public restrooms.
These tiny water droplets can carry pathogens such as Escherichia coli, Clostridium difficile, noroviruses and adenoviruses, and while many previous studies have shown that these pathogens can live in the toilet bowl for dozens of flushes, the potential increased risk of exposure could be the cause for concern. .
Scientists reported that in just eight seconds the particles zipped by at 6.6 feet per second, reaching 4.9 feet above the toilet. Larger droplets appear to land on surfaces within seconds, while smaller droplets appear to linger in the air for several minutes. studies found, or even more.
The researchers note the importance of understanding the effects of these particles in reducing exposure. John Crimaldi, the study’s lead author and professor of civil, environmental and architectural engineering, said in a news release on the study. “By creating compelling images of this process, our research can play an important role in public health messages.”
