Jogos Olímpicos de Verão de 2024 365 bwin Paris: Preocupações com a qualidade da água no Rio Seine

O Rio Seine é 🌧️ um ponto de referência 365 bwin Paris, tanto para os parisienses quanto para os turistas. Nas Olimpíadas de Verão de 2024, 🌧️ o rio será o centro das atenções, sediando eventos como o triatlo e a cerimônia de abertura, que, pela primeira 🌧️ vez na história dos Jogos Olímpicos, não acontecerá 365 bwin um estádio.

A partir do Pont Alexandre III Bridge, as corridas individuais 🌧️ de triatlo começarão com uma natação de 1,5 quilômetro, seguida por uma corrida de 40K de bicicleta – passando pelo 🌧️ Le Grand Palais e Champs-Elysées – e terminando com uma corrida de 10K pelo coração da cidade.

Uma equipe mista de 🌧️ revezamento, composta por quatro atletas (dois homens e duas mulheres), também começará no Pont Alexandre III Bridge, com cada atleta 🌧️ completando uma natação de 300 metros, seguida por uma corrida de 5,8K de bicicleta e 1,8K de corrida.

Se tudo correr 🌧️ bem, será um momento histórico, já que nadar no Seine tem sido ilegal por mais de 100 anos, devido aos 🌧️ níveis de poluição da água. No entanto, alguns advertem que ainda existem perigos potenciais abaixo da superfície do rio.

Recentemente, testes 🌧️ compartilhados com a tecnologia da Fluidion mostraram que o Seine ainda não é seguro para nadar, de acordo com os 🌧️ padrões estabelecidos pelo World Triathlon, devido a níveis elevados de bactérias E. Coli na água, potencialmente expostos a riscos graves 🌧️ à saúde.

As autoridades gastaram pelo menos €1.4 bilhão (R$1.55 bilhão) para limpar o rio. No mês passado, uma instalação de 🌧️ armazenamento de chuva foi aberta que pode armazenar 20 piscinas olímpicas de água para reduzir a pressão sobre a rede 🌧️ de esgoto e reduzir o risco de água residual ser descarregada no Seine, de acordo com um comunicado da Paris 🌧️ 2024.

Enquanto isso, times de triatlo de todo o mundo estão se preparando para o pior e esperando o melhor.

Preocupações com 🌧️ a qualidade da água

"Para mim, será muito frustrante e muito vergonhoso para a França, Paris e os Jogos Olímpicos se 🌧️ não pudermos fazer um triatlo", disse a triatleta francesa Jeanne Lehair 365 bwin uma entrevista telefônica.

A cidade de Paris está monitorando 🌧️ o local olímpico do Seine com seu próprio laboratório, mas a empresa Fluidion, fundada 365 bwin Paris 365 bwin 2012, também está 🌧️ verificando a qualidade da água do rio várias vezes por semana no Pont Alexandre III Bridge.

Os testes da Fluidion mostraram 🌧️ que, 365 bwin média, os níveis de E. Coli no Seine entre início de abril e final de maio foram de 🌧️ cerca de 3400 MPN/100mL. De acordo com os cálculos da 365 bwin , isso é mais de três vezes o 🌧️ nível necessário para "bom" qualidade da água, de acordo com os padrões do World Triathlon.

"Tivemos um tempo muito chuvoso nos 🌧️ últimos meses, causando muitos despejos combinados de esgoto 365 bwin Paris e rio acima", disse Dan Angelescu, CEO da Fluidion, 365 bwin 🌧️ 31 de maio via e-mail. "O impacto na qualidade da água é evidente, com picos bacterianos notáveis seguindo eventos de 🌧️ chuva."

Nearly all of France has seen 120 to 200% of normal rainfall over the past three months, with numerous episodes 🌧️ of flooding across the country, especially the north, according to Météo France.

The highest E. Coli levels recorded by Fluidion were 🌧️ 23590 MPN/100mL on May 2 and 13090 MPN/100mL on May 30, according to Angelescu. The May 2 result is more 🌧️ than 20 times higher than World Triathlon's "good quality" level, according to 365 bwin 's calculation.

More recently, following several days 🌧️ of dry and sunny weather, E. Coli levels on Monday 6 June were 2280 MPN/100mL, according to Angelescu, better than 🌧️ previous results but still above acceptable levels for swimming.

If E. Coli levels remain this high, the swimming leg of the 🌧️ triathlon will have to be cancelled, according to World Triathlon competition rules, unless the organization's medical committee decides that the 🌧️ race can go ahead.

E. Coli is not typically pathogenic itself, but it can indicate the presence of other pathogens, which 🌧️ can cause skin rashes, diarrhea, serious gastrointestinal diseases and, in very rare cases, even death.

However, Angelescu said that the water 🌧️ quality of the Seine is likely to improve significantly before July due to drier and sunnier summer conditions, which will 🌧️ reduce the frequency of sewage spills.

"It is highly speculative and scientifically unsound to project any conclusions about water quality during 🌧️ the Games based on recent trends," he said.

Angelescu said that "significant infrastructure projects" by the city of Paris designed to 🌧️ improve water quality will have a "substantial" impact.

"These tanks are expected to become operational before the Games, potentially becoming a 🌧️ ... Games changer," added Angelescu.

"When our instruments and data indicate that the water quality is good, we will be the 🌧️ first to dive in, headfirst!"

Angelescu's tone of optimism isn't universally shared.

French charity Surfrider Foundation Europe warned in April that they 🌧️ were "genuinely concerned about the health of athletes" after only one of the 14 samples collected by the organization indicated 🌧️ a satisfactory standard of water quality for swimming.

Two months later, the charity toldthat they have since taken five additional samples, 🌧️ with E. coli levels remaining "systematically above the guide values."

Paris 2024 said they still have "great confidence" in the city 🌧️ of Paris to improve water quality to the "necessary standard" in time for the Games.

"Generally, water quality in the Seine 🌧️ continues to improve every day," they said in a statement toin early June. "By the time of the Games, bacteriological 🌧️ pollution in the Seine will have been reduced by 75% thanks to the range of actions undertaken by our partners."

In 🌧️ a statement to 365 bwin , the city of Paris said that recent grey and rainy conditions have had a 🌧️ "major impact" on the Seine's water quality. A lack of sunlight – which would normally help to kill bacteria – 🌧️ has also contributed to the poor quality, they said earlier this month.

They added: "It is only when summer conditions (strong 🌧️ sunshine, high temperatures, prolonged absence of rain) become established that the Seine will gradually return to its 'summer' appearance, and 🌧️ that we will see a gradual and significant improvement in water quality."

Following multiple days of sunny weather in the first 🌧️ week of June, E. Coli levels improved near Pont Alexandre III Bridge, according to official data from the city of 🌧️ Paris shared with 365 bwin , but whether the good weather will last remains to be seen.

No precipitation trend, higher 🌧️ or lower than average, has been predicted for areas around Paris for the summer.

Since June 1, E. Coli levels declined 🌧️ from around 7000 UFC/100mL (equivalent units to MPN/100mL, according to World Triathlon) to just below 1000 UFC/100mL on June 9, 🌧️ according to official data.

However, World Triathlon's Competition Rules 2024 say that these levels are still too high for swimming, unless 🌧️ the organization's medical committee decides that the race can go ahead.
