– Mystery fog, ‘toxic’ sulfur odor covers Moscow (VIDEO) (RT, Nov 10, 2014):
A massive cloud smelling like ‘hell’ sparked a widespread panic in Moscow. Residents were afraid of a toxic gas after warnings to stay indoors.
The source of the rotten eggs smell turned out to be a leak from a sulfur dioxide processing facility at an oil refinery in Moscow, the Emergencies Ministry confirmed.
The city’s ecology watchdog and the Emergencies Ministry said that the level of hydrogen sulfide was over the permitted level for a short period of time, while the levels of sulfur dioxide remained within the norm. The two gases are byproducts of oil processing.
The smell created a wave of panic on local social media.
