A team of Russian researchers revealed that the environment inside the International Space Station (ISS) is contaminated. In their tests, they used advanced tools that can be utilized later to maintain the "health and safety" of spacecraft during long-term manned missions planned to other planets.

The new study was carried out by experts at the Russian Institute of Biomedical Problems and presented during the "Korolev's Reading" event, named after Sergei Korolev, the father of the Russian rocket industry and the leader of the Soviet Union's entry in the "Space Age".

In their experiments, the researchers said they used a new device named "e-nose" on the ISS, where it detected fungi and germs. The e-nose is capable of monitoring pollution by capturing the gases emitted by these organisms.

In their report, the researchers didn't determine the type of the germs and fungi found inside the ISS, but they are likely non-harmful species that often exist in the air.

The air test conducted in the ISS was aimed at testing the "e-nose" and its efficacy in detecting the types and sources of pollution, in order to use it in monitoring contamination levels inside spacecraft in future interplanetary missions.

Based on the results of the primary tests, the researchers said the "e-nose" has proved its reliability in detecting fungi and germs in different parts of the ISS.

They suggested the new device could be used in the future to monitor all the parts and devices in spacecraft in order to prevent germs growth onboard, or to determine the type of any detected germ so astronauts can swiftly address the problem and halt its development while the spacecraft is in deep space, far away from the Earth, where it requires prevention to guaranty the continuation of its mission.



Latest Tests Show Seine Water Quality Was Substandard When Paris Mayor Took a Dip

Tests results released Friday showed the water quality in the River Seine was slightly below the standards needed to authorize swimming — just as the Paris Olympics start.

Heavy rain during the opening ceremony revived concerns over whether the long-polluted waterway will be clean enough to host swimming competitions, since water quality is deeply linked with the weather in the French capital.

Paris Mayor Anne Hidalgo took a highly publicized dip last week in a bid to ease fears. The Seine will be used for marathon swimming and triathlon.

Daily water quality tests measure levels of fecal bacteria known as E. coli.

Tests by monitoring group Eau de Paris show that at the Bras Marie, E. coli levels were then above the safe limit of 900 colony-forming units per 100 milliliters determined by European rules on June 17, when the mayor took a dip.

The site reached a value of 985 on the day the mayor swam with Paris 2024 chief Tony Estanguet and the top government official for the Paris region, Marc Guillaume, joined her, along with swimmers from local swimming clubs.

At two other measuring points further downstream, the results were below the threshold.

The statement by Paris City Hall and the prefecture of the Paris region noted that water quality last week was in line with European rules six days out of seven on the site which is to host the Olympic swimming competitions.

It noted that "the flow of the Seine is highly unstable due to regular rainfall episodes and remains more than twice the usual flow in summer," explaining fluctuating test results.

Swimming in the Seine has been banned for over a century. Since 2015, organizers have invested $1.5 billion to prepare the Seine for the Olympics and to ensure Parisians have a cleaner river after the Games. The plan included constructing a giant underground water storage basin in central Paris, renovating sewer infrastructure, and upgrading wastewater treatment plants.
