French river journey aims to test pollution levels in Europe's rivers

France (AFP) – A French man has embarked on a solo rowing expedition from Poland to France to highlight the pollution of waterways across Europe.

Christophe Gruault set off from Poland's capital Warsaw on Monday in a customised rowing boat six metres long and only 60 centimetres wide and hopes to reach Paris on 18 June.

His intended route of 2,023 km will lead through five countries: Poland, Germany, the Netherlands, Belgium and France and will take him along 22 of the continent's rivers.

"The aim of the game is to show that what's beautiful is fragile, and what's fragile needs to be taken care of," the 58-year-old told French news agency AFP shortly before departing from a bank of the Vistula River.

Gruault plans to raise awareness by meeting high school students along the way and to contribute to scientific research on what is polluting Europe's rivers and causing them to dry up.

"I'm going to take environmental DNA samples that I'll pass on to the scientists," Gruault said.

The journey is supported by the National Museum of Natural History in Paris, where researchers will study Gruault's samples and observations.

For Denis Duclos, the museum's director of European and international relations, the expedition offers insight into the condition of Europe's main waterways.

"It will be interesting to take samples before the major cities on the route and after the major cities on the route, in order to see whether the cities have any consequences on the treatment of pollution," Duclos told AFP.

To facilitate the task, the explorer's team equipped his boat with a system for reversing the movement of the oars, allowing the rower to face forward, "a system which is unique in the world," Gruault added.

He plans to row up to 50 km a day, which he said had required improving his physical fitness.

"First of all I needed to balance my body and work on the muscles to create strength, to put on a bit of bulk," Gruault said.

"And then work on the heart, it's an important engine after all".

Pollution in Poland's rivers came into the limelight last year when nearly 250 tonnes of dead fish were recovered in July from the Oder River that runs through Poland and Germany.

Huge numbers of dead fish washed up along the banks of the Oder River between Germany and Poland, Friday, Aug. 12, 2022.

Polish authorities later said toxic algae was to blame, ruling out industrial pollution as the cause.

But German authorities called it a "man-made environmental disaster", saying the algae growth had been sparked by the introduction of salt into the waters.
