The water quality of some swimming pools in Nanjing exceeded the urea standard (photo) Yesterday, the high temperature in Nanjing was 37 掳C, and at 2 o'clock in the afternoon, outdoor swimming was like a sauna day, and swimming became a good choice for citizens to cool down and cool off. Braving the scorching heat, this reporter visited a number of indoor swimming venues and some outdoor and open-air swimming venues in Nanjing, and found that almost all swimming pools were full, but the sanitary conditions of many swimming pools were not optimistic.

Yesterday, the relevant person in charge of the Environmental Sanitation Department of the Nanjing Municipal Center for Disease Control and Prevention told reporters that they had worked with inspectors from the Nanjing Municipal Health Supervision Institute to extract water samples from major swimming venues in Nanjing for monitoring, mainly analyzing the total number of bacteria, coliform bacteria, free residual chlorine, turbidity, urea, and other indicators related to human health.

"But judging from the test results of previous years, there will be swimming pools that fail to meet the standards every year. The person in charge said that one of the prominent problems is that urea exceeds the standard. The main source of urea in water is human sweat. Of course, it is not excluded that someone urinates in the pool.

The urea in the water quality is high, which will be a certain irritation for some patients with allergies. An inspector told reporters that it is not difficult to rectify most of the swimming pools that fail to pass the inspection, most of them are fined and ordered to rectify the unqualified swimming pools. According to the regulations, the swimming pool must replace some of the clean water every day, and it is also necessary to use a sewage suction machine to remove the dirt from the bottom of the pool, especially the cuticle that has fallen off the human body, before the next day's opening.

In addition, all water needs to be drained regularly, the venue is cleaned and replaced with new water. However, it is not realistic for some large swimming pools to empty all the water in the pool, and it is generally closed for three or four days, and some consumers who apply for annual cards will have opinions.

(Yang Pu Yu Dandan) Our reporter visited the swimming pool and said that the child can't manage to pee, but the swimming pool will be disinfected every day Wutaishan Natatorium: At 2 o'clock in the afternoon, many people were queuing up at the waiting area at the entrance of the Wutaishan Natatorium, and many people were buying drinks. When entering the pool, the staff did not require swimmers to show proof such as health cards on the spot, but only required that they need to take a bath before entering the water, mainly to do a basic body cleaning for swimmers and adapt to the lower water temperature in advance, so as to prevent uncomfortable symptoms such as foot cramps caused by excessive temperature difference in the water directly.

The reporter noticed that there were five or six lifeguards patrolling the high platform on the shore, or looking at the pool from a high place or walking around by the pool. An inspector said that it is necessary to be diligent in the eyes, legs, and mouth in order to detect potential dangers at the first time and ensure the safety of swimmers.

Mr. Zhang, who was resting by the pool, told reporters that there were also many "non-slip" and "don't frolic" tips around the swimming pool. "Nanjing's regular indoor swimming pool is still relatively reassuring. Mr. Zhang, a swimmer, said that there are many people in the shallow water area, and the water temperature is also very high, like dumplings, and the pool water is not very clear, which is probably caused by a large number of people or children urinating randomly in the shallow water area.

Comparatively speaking, the deep water area has fewer people and better water quality. In this regard, a person in charge of the venue said that the child can't control the peeing, but we disinfect the pool every day, which should have little impact on the swimmers.

National Exhibition Q Soft Children's Play Water Park: At 2:30 p.m., the reporter came to the Xinzhuang International Exhibition Center, The Q soft children's play water park here is a newly opened water amusement project The reporter saw that the ticket price at the door was 80 yuan for children and 20 yuan for adults, and asked a parent at random.

The answer was: "The group purchase ticket bought from the handle online is 39 yuan, and two people can enter.

But the reporter walked around inside and found that in fact, adults mainly accompany children after coming in, Nine out of ten parents are sitting on the edge of the inflatable pool and watching their children play in the pool, The reporter noticed that there are 4 inflatable pools, each about 200 square meters, The water depth is 30 centimeters, and there are some water inflatable toys in it, Some adults reflected: "This water amusement project, charging adults money is a bit unreasonable, adults are mainly taking care of children, where is the opportunity to play? However, a person in charge of ticketing told reporters that the business of this project is losing money, mainly because of the low price of tickets on the Internet to attract popularity, play the brand, filter all the pool water with quartz powder and disinfectant every day, and completely replace all the pool water every two days to ensure that the water quality meets the standard.

However, some parents questioned that they obviously smelled a smell when they looked at their children by the pool, suspecting that it was the smell of the unclean water in the pool, and the person in charge said that it may be the smell of the carpet dipped in water, and they will vacuum the carpet clean, but it is difficult to control the children's random peeing.

Olympic Natatorium: At 7 o'clock in the evening, the reporter saw in the Olympic Natatorium that most of the swimmers here came by car due to the large number of people and cars, many cars could not find parking spaces, especially the parking spaces near the swimming pool were basically full. Some car owners drove around the parking lot in circles looking for a seat.

According to the citizens who swim here, the swimming pool equipment here is relatively new, and the water in the swimming pool must be filtered and disinfected every night. After disinfection, I heard that alum was added to the water for precipitation, and the precipitated debris was vacuumed. After vacuuming, the amount of water is reduced, and then the pool is replenished, so it is more reassuring.

The reporter noticed at the door that the security guards of the swimming pool were stricter and asked carefully about customers who did not bring swimming gear. Intern Zhou Yuan, Li Jingwei, reporter of this newspaper, Wu Sheng, Fan Xiaolin Two questions: What will be the problem if the pool is not clean?銆€銆€It is easy to suffer from dermatitis, and may also have diarrhea Du Changming, the attending physician of the Department of Dermatology of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, reminds readers that swimming in swimming pools must first prevent dermatitis, and some citizens with sensitive skin are prone to dermatitis after swimming.

The skin will show redness, rash, stinging, itching, peeling, etc. In addition, Deputy Chief Physician Chen Zhuo, a urology expert, reminded that urinary tract infection is also one of the diseases that swimming is prone to. Some citizens have had the experience of having diarrhea after coming back from swimming, especially some children.

Many people think that it is a cold, but in fact, it is related to the unclean water. Ju Juan, director of the Department of Internal Medicine of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, told reporters that in the outpatient clinic, some citizens only have diarrhea symptoms after a few days of swimming, and they are generally diagnosed with acute enteritis.

Some people mistakenly think that it is caused by eating unclean food or catching a cold, but it is actually caused by accidentally swallowing excessive pool water such as E. coli and other bacteria during swimming. Some infectious diseases can also be transmitted through swimming pools, for example, if the swimming pool is not thoroughly disinfected, the probability of cross-infection with conjunctivitis will be greatly increased if only one person in the pool suffers.

After infection with conjunctivitis bacteria, the general incubation period is 1~3 days, and the symptoms of red and swollen eyes, conjunctival hyperemia, tearing, increased discharge, and dare not open eyes are often manifested at the onset of the disease. Some people often experience water in their ears and choking on their nose when swimming, and if the pool water is not clean, the bacteria they carry may lead to sinusitis, otitis media and otitis externa. Among them, the symptoms of sinusitis are similar to those of a cold, and the public should pay attention to the difference and seek medical attention in time if necessary.

Here are a few ways to identify whether the water in the pool is clean, for example, an eight-lane standard swimming pool can stand on the side of the pool and see if the line of sight can be seen through the water to see the fourth and fifth lane lines. If you can't see it, the water is cloudy.

Members of the public can pay attention to the bottom of the swimming pool or the water outlet next to the swimming pool to see if there is any continuous flow of water in and out. If there is, it means that the water circulation disinfection device is working normally. For citizens who find it difficult to distinguish whether the pool water is clean or not, experts also give suggestions to prevent diseases caused by unclean pool water.

For hair and eye care, wear a silicone swim cap and remove contact lenses. Patients with allergic rhinitis, sinusitis, otitis media and other diseases should try not to swim in the pool to avoid allergens or bacterial stimulation in the pool water. When swimming, after the ear is flooded, it is necessary to remove the residual water in the ear in time, if it is not removed, it is easy to cause otitis media and otitis externa.

At about 8 p.m. yesterday evening, a young man in his 20s was swimming in an artificial reservoir in the scenic area of the Sun Yat-sen Mausoleum in Nanjing. The reporter learned from interviews that although there is a "no swimming" sign on the side of the reservoir, there are still many people who come to swim recently.

According to Mr. Wu, an eyewitness, at about 8 o'clock last night, he went to the reservoir near the Nanjing Institute of Physical Education in the scenic area of the Sun Yat-sen Mausoleum to swim and found two young men asking for help, saying that when their companion was swimming in the middle of the reservoir, a fierce man plunged down and never came up, and now no one can be found.

Mr. Wu said that the reservoir, which is known locally as the "Xiwazi Reservoir", is about 250 meters long and more than 100 meters wide. There are shallows within 2 meters of the shore, but the water in the middle is so deep that no one with the best water can reach the bottom. The two young men said that the three of them were Liuhe people, and they came to swim last night.

At Mr. Wu's suggestion, the two young men called the police, and the 110 police soon arrived, but the police checked the scene and did not find the whereabouts of the missing young man. Since there were no professional salvage equipment, the police took the two young men back to the police station to make a record first. It is understood that there is a large sign next to the reservoir that reads "No Fishing, No Swimming".

At present, the police are contacting a professional salvage team to find the whereabouts of the young man. Drowning in the Pool, Others Still Thought He Was Holding His Breath At about 4 p.m. yesterday, a male swimmer in a swimming pool in Jiangning, Nanjing, drowned in the pool for some reason, and the whole person was lying on his back at the bottom of the pool.

At around 5 p.m., the reporter received a report and rushed to the scene of the incident. A middle school girl told reporters that she was swimming in the deep water of the pool when she found a young man in his 30s next to her lying on his back at the bottom of the pool.

"At first I thought he was holding his breath in the water, but I thought he was very powerful, very good in the water. The little girl said that she swam a little more and came back to find the man still at the bottom of the pool, and still in his original position.

At this time, several other swimmers also noticed this, and everyone began to gather around, and some people pointed and said, "Why is this person so powerful, holding his breath for so long." But then someone felt that something was wrong, because the man had no expression on his face, so he hurriedly called for help.

According to eyewitnesses, the man was later "lifted" from the water by three lifeguards face down and with his feet up. Two men pulled him by the feet, and one lifted him underneath. A middle-aged male swimmer said that the man's condition was already serious when he was rescued, and the lifeguards took some measures and rushed him to the hospital.

Some eyewitnesses at the scene speculated that although the drowning swimmers had been drowning for a long time, they should not be life-threatening. "When he was rescued from the water, I found that he was already able to breathe on his own," one swimmer told reporters.
