Every time we flush the toilet, a small invisible “rash” occurs in the bathroom. It is not a literary exaggeration: science calls it ‘toilet plume’, or toilet plume: a phenomenon by which a Water discharge launches thousands of microscopic particles into the air loaded with everything you just deposited in the cup. A piece of advice. For years, it’s been pretty simple: lower the lid before pressing the toilet button. However, recent research suggests that this gesture, although useful, is not the definitive shield we thought. A microscopic volcano. When the water enters the cup with force to clean the residue that we have deposited, the impact generates bioaerosols. These droplets are so light that they can remain suspended in the air for minutes or even hours, something that can be quite dangerous for those people who have low defenses. A biological cocktail. According to the scientific reviews that have been done on the matter, the invisible clouds we are talking about are real cocktails with numerous biological agents. For example, bacteria such as Escherichia coli, Salmonella, Shigella and Clostridium. This is something that is magnified when we say that in a single gram of feces there can be up to 1,000,000,000,000 viral particles. And this is something that is magnified in public bathrooms, as scientific studies have shown that bacteria are not only found near the toilet, but also on the floors and sinks, confirming that pollution does not remain stagnant in the air. The myth of the cover. A priori, lowering the lid should be a clear solution to prevent bacteria from escaping, and although it helps a little, the reality is that it is not perfect. According to science, Lowering the lid reduces the dispersion of visible droplets by 30 to 60%being a substantial improvement to prevent heavier particles from landing even on the toothbrush. However, there is a design problem: the gap between the cup and the seat. The finest aerosols (particles less than 1 µm) are expelled under pressure through these slots. In experiments with viruses such as MS2, it has been proven that up to 57% of aerosols manage to escape even with the lid closed. And once outside, their size allows them to avoid many conventional air filters. It’s not just disgust. As microbiologist Raúl Rivas explainsthis is not just a debate about aesthetic hygiene. Flushing the toilet without lowering the lid releases many viruses and bacteria that may even be resistant to antibiotics. But this is something that is greatly amplified in public bathroomswhere ventilation is poor and where there are a large number of people per day. Here there is a high concentration of particles that, due to their small size, can be inhaled or deposited on the surfaces we touch such as the doorknob or the paper dispenser. What should be done. Science doesn’t say to stop lowering the cap, as it’s still best for larger droplets, but it suggests it’s not enough. That is why the tips that we can apply especially in the domestic sphere are the following: The summary is quite clear: the toilet is a very efficient microbicidal aerosol generator, and lowering the lid is the first step although it does not replace good hygiene and ventilation.
