of central Siberia.MOSCOW (AFP) - Russia's emergency situations ministry said it was dispatching experts to a Siberian province to find out why yellow and orange snow has been falling in several villages, the ITAR-TASS news agency reported.
"A chemical test unit will be sent to Omsk.... It's main task will be to investigate pollution in the region and establish the degree of danger represented by the anomalous snow fall," the agency quoted an unnamed official from the ministry as saying.
Snow ranging in colour from light yellow to orange and carrying a distinctive "musty" odour was observed Wednesday in five districts of Omsk province, which lies in western Siberia and borders Kazakhstan, ITAR-TASS said.
"Residents are advised not to use snow for their household or technical needs and to limit walking, either by people or their pets, in this area," the official said.
The affected area measures about 1,500 square kilometres (580 square miles) and is home to over 27,000 people, the ministry said.
Officials have already been gathering snow samples, it added.
The Omsk province is known as a centre of the oil industry and the provincial capital is among Siberia's largest cities.
