Why do humans not run out of hysteria and alarmism? Because you can not flush it down the toilet! Oh what nice example of a junk journalism!
If this was so dangerous, then we must be all dead now! Your bathroom is a chemical weapons battle field! Caution: Satire
Why is this irritating junk journalism? The study is limited to commercial toilet flushes. "Commercial toilets, also known as flushometer-valve toilets, are typically found in commercial, institutional, or industrial restrooms in places such as airports, theaters, stadiums, schools, and office buildings." (Google AI generated)
Fact is that the toiled flushing mechanism for residential toilets was not really improved for several decades. So it is worth thinking about it not least because it wastes a lot of potable water every time!
From the abstract:
"Aerosols can transmit infectious diseases including SARS-CoV-2, influenza and norovirus. Flushed toilets emit aerosols that spread pathogens contained in feces, but little is known about the spatiotemporal evolution of these plumes or the velocity fields that transport them. Using laser light to illuminate ejected aerosols we quantify the kinematics of plumes emanating from a commercial flushometer-type toilet, and use the motion of aerosol particles to compute velocity fields of the associated flow. The toilet flush produces a strong chaotic jet with velocities exceeding 2 m/s; this jet transports aerosols to heights reaching 1.5 m within 8 seconds of initiating a flush. Quantifying toilet plumes and associated flow velocities provides a foundation for future design strategies to mitigate plume formation or to disinfect pathogens within it."
