According to the plan, on the evening of July 26, 2024, 160 boats carrying more than 10,000 athletes and athletes were welcomed by about 600,000 people near the Notre Dame Cathedral and the Louvre Museum.

Things began to change in the 1990s, thanks to stricter controls on pollution and the construction of new wastewater treatment plants. Today, 99 percent of the wastewater in the Paris region is treated.

Interventions in recent years to clean up China have effectively allowed a wide variety of fish to return to the river. Cat fish 243 cm in length was discovered in the summer of 2020. However, this does not mean that people can do Chinese bathing safely in the short term.

Among the parameters analyzed to assess the health status of river water, for example, quantity Escherichia coli (E – Goalie), A bacterium that lives in the lower part of our gut and thousands of other animal species. This is very important for our survival, but changing it can cause serious infections in the host. Levels, according to the latest data E – Goalie They are 70-80 percent above the threshold where they are considered safe in seawater.

Jean-Marie Mouchel, director of the UMR METIS Division of Environmental and Aquatic Research at Sorbonne University, said she was optimistic about the project’s success.
