The Russian news agency states that orange and yellow snow fell over a 1,500 square kilometer (1,000 square miles) radius, which is populated by more than 27,000 people. Experts have established that the substances in the snow are not toxic, although the iron content was found to be four times higher than it should be. Authorities have warned residents not to melt the snow for water purposes and to avoid stepping on it wherever possible, as the cause of the phenomena is not yet known. An emergency service official told Novosti that they have made inquiries to Kazakhstan about the possibility of industrial pollution from the neighbouring country.
