The presence of perchlorate compounds on the surface of Mars is highly toxic to biological cells!

BEIJING, July 6 (Xinhua Zhang Mengran) Is human hope of finding extraterreso-Earth life on the surface of Mars dashed? A planetary scientific paper published in the British journal Nature's Scientific Report on the 5th pointed out that the surface of Mars, called perchlorate compounds, so the surface of Mars may be sterile, highly toxic to biological cells.
scientists have also questioned the native habitability of Mars in light of the serious impact of perchlorates on the planet's environment.
this time, scientists Jenny Wardworth and Charles Cook of the University of Edinburgh analysed the potential activity of perchlorates and their impact on the viability of Bacillus aureus, a pollutant commonly found in spacecraft.
team found that magnesium perchlorate produces bactericidal properties under short-wave UV rays, similar to lying on the surface of Mars.
In addition, if the perchlorate concentration is similar to that of perchlorate concentrations in the weathering layers of the Martian surface, such as dust, soil, and gravel, the nutrient cells of Herbacteria will lose their viability within minutes in this Mars-like environment."
team also suggested that iron oxide and hydrogen peroxide, two other components on the surface of Mars, were 10.8 times more likely to kill cells than purely perchlorates, in a joint effort with perchlorates.
that although the surface of Mars has been suspected to be toxic for some time, there has been a lack of important evidence.
the new discovery proves that the surface of Mars is highly toxic to cells, caused by a "toxic cocktail" of oxidants, iron oxides, perchlorates and UV rays.
scientists say the findings are important in "responding to potential pollution to Mars caused by machine and human exploration."
