Its becomes a habitat: mussel types show progress through renovation!

In an astonishing turning point for the Seine in Paris, the discovery of endangered mussel species is a strong sign of improving the water quality in this historical flow. So the Kleine Zeitung that the rhombic river mussel, the stream mussel and the split-off pond shell on the effects of urban lighting on the biodiversity were discovered. All three types are on the list of endangered species. These newly won signs of life are the result of extensive investments in water treatment, which were made in Paris in the run -up to the Olympic Games last summer. Incredible 1.4 billion euros flowed into sewage treatment plants and sewage systems to improve water quality.

challenges remain

Despite the positive news, the question of water quality remains pressing. While the mussels act as bioindicers, current tests show how they are documented in the results of the triathlon of August 5 that the water quality does not consistently correspond to the necessary standards. According to fluidion resulting in a sample on the Alexandre III bridge worrying values ​​of 1338 e.coli/100 ml, which is above the acceptable limit. This suggests that despite the progress in water quality, there is still the risk of contamination from bacteria and other pollutants, which is particularly problematic for swimming competitions.

These challenges shed light on the persistent difficulties associated with the preservation of water quality in the river. The “gray zone” of water quality, as it is called, indicates that there are still unclear risks that may affect both the health of swimmers and the ecosystem that could affect SEN. Careful surveillance and other measures are necessary to make its flora and fauna, as well as for leisure activities.
