 Escherichia coli in swimming waters of Tokyo Olympic Games


The water temperature was too high during swimming, and I was a little worried about it. It smelled like sewage. This is the swimmers tucking of local water quality after the open water test in August 11th Tokyo Olympic Games.

Among these athletes are not only Japanese native athletes, but also veterans who have participated in several Olympic Games, and even Olympic champions. To varying degrees, they are worried about the open waters of the upcoming Olympic Games and the waters of the triathlon.

This is not the first time that problems have arisen in the waters of the Tokyo Bay, where two years ago it was reported that E. coli exceeded the standard by more than 20 times. So, with less than a year to go before the Tokyo Olympics, is Japan really ready?

The competition venue is in the waters of Tokyo Bay.

It smells like a sewer.

Taishore Park, Tokyo, Japan, is the venue for the Triathlon and Open Water Swimming Competition of the Tokyo Olympic and Paralympic Games in 2020. On August 11, the Olympic swimming test in open water was held here.

Thirty-five swimmers participated in the test, including 22 male and 13 female.

As a result of the recent high temperature in Japan, the temperature has been above 31 degrees Celsius, and 57 people have been killed in Japan even within a month. Therefore, although the race started at 7 a.m., the local temperature still exceeded 30 degrees Celsius.

Merleary, the gold medalist in the 10-km swimming marathon at the London Olympics, took part in the test. After completing the mens 5-km race, he said, I feel good in the first two kilometers, but it feels too hot to swim back.

Tokyo Taishore Park is currently hosting the World Junior Rowing Championship, which is also an Olympic test competition.

We need to make sure that athletes are safe in competition. Judging from this test, whether it is advanced to 5 a.m. or other time depends on the water temperature at that time.

Hot weather has become a major problem for the 2020 Tokyo Olympic Organizing Committee. In order to reduce the impact of hot weather, the Tokyo Olympic Organizing Committee has adjusted the competition time of many events, including marathons.

And there are more than just high-risk problems in this area. At the end of the days test, several competitors even reflected that there was a foul smell in the water. To be honest, it smells like a sewer.

Sewage into Tokyo Bay, E. coli more than 20 times the standard

The water quality problems of the Tokyo Olympic Games did not arise this time. In 2017, the Tokyo Olympic Organizing Committee and the Tokyo metropolitan government tested the water quality of the Tokyo Taichang Seaside Park, but the results were not satisfactory.

The Japanese Broadcasting Association (NHK) reported that the water quality of open water swimming was tested for 21 days, with only 10 days reaching the standard, less than half; the water quality of the Ironman Triathlon was tested for 26 days, with only 6 days reaching the standard, less than a quarter.

What is even more striking is that the E. coli index in this area has reached about 21 times the standard value stipulated by the International Ironman Triathlon Alliance, and the E. coli index has exceeded the standard value of the International Swimming Federation by 7 times.

The explanation given by the Tokyo Olympic Organizing Committee is that 80% of the sewers in the Tokyo metropolitan area are combined sewers. When rainfall is too high, sewage in the sewers will flow into the Tokyo Bay. Nevertheless, the organizing committee has no intention of replacing the venue.

It shouldnt be like this. Its not up to the Olympic standards. John Cotts, chairman of the IOCs Tokyo Olympic Games Coordination Committee, regretted the result.

In a statement, FINA said, FINA will continue to cooperate with the Tokyo metropolitan government and the Tokyo Organizing Committee for the 2020 Olympic Games to ensure the best competition environment for the open water swimming competitions of the 2020 Olympic Games.

In less than a year, is Tokyo ready?

Under various pressures, the Tokyo Olympic Organizing Committee has promised to take measures to improve water quality before the Olympic Games to ensure that it meets the competition standards. It is understood that they have since adopted a hierarchical filtration system to improve the water quality of the competition waters.

The test results can not be obtained within 48 hours, but from the results submitted previously, the water quality is still very good. David Gerrard, a member of the FINA Medical Committee, confirmed the Tokyo Olympic Organizing Committee during the test of the Open Water Swimming Olympic Games.

However, throughout the preparatory process for the Tokyo Olympic Games, in fact, it has not been smooth sailing, a variety of problems emerge in endlessly.

In July 2015, the Tokyo Olympic Organizing Committee issued the Olympic emblem designed by Erichiro Sayono, but the design fell into a wave of plagiarism and was eventually abandoned. Finally, the Japanese artist Nozoko Nozos Matsumoto was chosen as the Olympic emblem.

There are many twists and turns in the problem of the main venues of the Olympic Games. Pritzker Architecture Award winner Zaha Hadid initially won the design of the main stadium, but was subsequently opposed by a large number of Japanese local architects. In July 2015, the Organizing Committee of the Olympic Games abandoned Zahas plan for the high cost of construction.

In the subsequent selection, Japanese designer Kengo Kumaki won the right to design and construct the main stadium of the Olympic Games. But in 2016, it was found that there was no reserved place for the Olympic torch in the design of the main venue, which violated the regulations of the International Olympic Committee for setting up the Olympic torch platform.

Recently, South Korea publicly questioned the food safety of Fukushima provided during the Tokyo Olympic Games in Japan, and said that the South Korean delegation only consumed food from home during the Tokyo Olympic Games, and hoped that Japan would simplify quarantine measures...

With less than a year to go before the Tokyo Olympics, the time left for the Tokyo Olympic Organizing Committee is indeed limited.
