Citizens were baffled when blue snow covered the ground in St Petersburg, Russia.
The odd phenomenon was captured on video after the colored snow fell this week on the city in Leningrad Oblast, President Vladimir Putin’s hometown.
Residents were shocked at the incident and became worried it could have been due to toxic chemicals in the atmosphere.
Some believed the snow was a result of the demolition of the city’s chemical-pharmaceutical research institute.
According to local media, experts said the colors could have been caused by cobalt, a metallic element, or methylene blue, a substance used in some medical treatments.
Samples were taken to a laboratory for analysis and an investigation into the incident has been launched.
For the sake of the community, we really hope that there is no connection to the infamous ‘blue ice’ that occasionally falls from airplanes.
It is not clear yet exactly why the latest blue snow has fallen.
But after an average of 1 centimeter (0.39 inches) fell, citizens have been simply shoveling the phenomenon out of the way to go about their daily lives.
In 2015 it was reported that, Blue snow has covered Chelyabinsk, a Russian town in the Ural Mountains, almost two years to the day after a meteor traveling at over 34,000 miles per hour exploded over the city with the force of 500 kilotons of TNT, creating a shock wave that injured over 1,500 people. Is something attracting anomalies to Chelyabinsk in mid-February? Why is Russia having a season of colored snow?
Local resident Dmitry Kudryonok said the snow smelled like iron. News presenter Alexandra Artamonova from Telefact, who wasn’t catching snowflakes on her tongue, nonetheless said she could “feel a sweet taste in the mouth.” She also reported that others complained of having sore throats after breathing near the snow. Most residents wanted an explanation before cleaning off cars and sidewalks, but neither the Emergencies ministry nor the Ministry of Ecology gave any comments.
Finally, the Viteks Company released a statement that one of its factories in Chelyabinsk was making blue dye for Easter eggs and had a “minor” spill. Not surprisingly, it gave assurances that the chemicals causing the blue snow were not toxic and posed no health hazard.
