Flap cloth gasket bacteria on the toilet is easily adsorbed

When the toilet flushes, it will bring the bacteria to the air? How much do these bacteria harm the human body? Is the toilet lid really preventive? With these problems, Dr. Chen Zuhui, the first public health professional attached to the Jinan University, said that the number of bacteria that the family usually uses for “siphonic” toilets is limited. It is not meaningful to cover or not cover the toilet. The key is to keep the bathroom (toilet) Ventilation and drying of the decoration effect diagram. It is best to close the door and open the exhaust fan when going to the toilet.

When the bacteria flushes with the cyclone toilet, the bacteria will vacate?

"When the toilet flushes, the water will whirlpool under impact and form an aerosol (collectively referred to as solid particles or liquid droplets suspended in the air.) In theory, if the toilet lid is not covered at the time, the bacteria are It is possible to vacate through this method.” Chen Zuhui said that these bacteria are floating in the air, or attached to the walls, toothbrushes, towels and other objects.

However, not all the bacteria in the toilet will follow the cyclone. Studies have found that some bacteria prefer to go deeper, and those bacteria that contain more lipids inside cells tend to accumulate on the surface of water bodies. If there is a cyclone that can pick up bacteria in the water, these bacteria that have accumulated on the surface of the water body are suddenly transformed into “vanguards”.

Experiments have shown that E. coli can be concentrated in the range of about 1 meter in diameter around the toilet bowl within 2 hours after flushing; Salmonella can spread to the same range within 30 minutes; while Clostridium is mainly Within 60 minutes, gather in the toilet seat to a height of 25 cm above the toilet.

In some of the longer-term experiments, bacteria can spread throughout the bathroom at very low concentrations. However, in these studies, there was no record of bacterial spread to a height of 6 meters. As for how long these bacteria can stay in the air, there is no conclusion.

The size of the spread of bacteria depends on the size of the cyclone power, and the power of the cyclone will change with the type of toilet. In the above tests, the most common "siphonic" toilets in the current family were used. Compared with toilets flushed by the bottom of gravity valve, which was earlier flushed with water, the “siphon” toilet flushes water with smaller cyclones, and the same microbes used for flushing have only about 1 of the former. /14.

"When the household's commonly used 'siphonic' toilet flushes, because of the small amount of water and the low pressure, the amount of bacteria that the cyclone brings is limited." Chen Zuhui said that instead of the toilet on the plane, the flushing pressure is very high, plus the aircraft's The bathroom space is small and not ventilated. Passengers should flush the toilet with a toilet to prevent the bacteria from accumulating in the air.

Bacterial pathogenic capacity is limited In most households, toilets, toilets, and showers are all in the bathroom. Toothbrushes, mugs, towels, etc., are in the same room as the toilet. The toilet flushes and the bacteria empties. For a time, people are panic-stricken and fear that the spread of bacteria will cause potential harm to the human body.

In this regard, Chen Zuhui said "not to worry too much". He said that with the cyclone vacillating bacteria, the types can be varied: some are pathogenic bacteria, some are conditional pathogenic bacteria, and there are beneficial bacteria. "There is already a large amount of bacteria in the air. Even pathogenic bacteria must reach a certain amount before they are harmful to the human body."

The SARS virus transmission in the sewers of the Hong Kong Amoy Gardens (SAR) period during the SARS period confirmed the possibility that excreta in toilets could transmit viruses through the atmosphere. In response, experts say that this is an extreme situation. The potential harm caused by the toilet cyclone in daily life is not great.

As for the suggestion that “the toilet lid should be covered when flushing the toilet”, Chen Zuhui said that the lid or the toilet lid is not very meaningful. "If not covered, it cannot be ruled out that the bacteria inside will be released into the air with the cyclone; if covered, the bacteria may adhere to the toilet seat and may come in contact with the skin. If the skin is damaged, it may cause skin infections."

"If you want to reduce the spread of the disease, the most important thing is to maintain the ventilation and drying of the bathroom." Chen Zuhui suggested that frequent use of exhaust fans or windows should be used to maintain the ventilation and drying of the bathroom. When going to the toilet, it is best to close the bathroom door, open the exhaust fan, do not immediately turn off the exhaust fan after flushing the toilet, but open it for another 2 minutes, let the circulating air away bacteria floating in the air . In addition, the toilet should be cleaned regularly, do not wait for yellow stains and then wash.

As the weather gets colder, many people like to put a flannel washer on the toilet. Experts say that this is a bad habit. The flannel seat is the best medium for bacteria, and water, excrement, and bacteria are easily adsorbed and retained. The possibility of contamination and spread of disease is greater. Therefore, it is better not to use it. If it is not necessary, it should be frequently cleaned, replaced, and disinfected.
