Science solves the mystery of the rose lake in Australia

A lake in Melbourne, Australia, has turned pink, causing confusion and euphoria for online newscasters, but local residents have not been shocked. Salt Lake, located in Westgate Park, has turned pink several times over the past decade, making local people get used to it. But what is the secret behind this strange transformation of the color of the lake? Victoria Gardens officials told the media that there is nothing wrong with the lake where there are no industrial waste and no leaks of toxic substances can cause water color change.  However, there are several factors such as high salinity, low precipitation, high temperatures and combined sunlight have all played a role in lake color change. They called everyone to enjoy the view of the lake but warned against direct contact with the water. According to Mark Norman, a leading environmental scientist, water itself is not dangerous. However, there are a few unlucky people who have felt pain in the eye because salt crystals are similar to what happens if brushed with brine. Norman also said there was a high concentration of green algae at the bottom of the lake. The presence of a single cell called Dunaliella, the main culprit in lake color change, was discovered every summer. Logically, the decrease in water volume in the summer results in increased salt concentration in the lake, which is due to its natural color in winter and autumn. In 2013, a study was carried out by the Extreme Micro Biome Project to solve the lake puzzle, using scientific methods and methods, and collecting samples from several sites of the lake. They concluded that algae, bacteria and bacteria are abundant in this exotic environment. (Dunaliella Salina) is responsible for producing a pink color called carotenoids. In other studies, she said that in addition to the single cell (Dunaliella) there are microbes producing a similar dye (Salinibacter) and these microbes are the reason for the pink color of the lake.
