Smog from wildfires raging in western Russia engulfs Moscow, officials warn of health risks

PEREDELTSY, Russia (AP) — Moscow was engulfed Wednesday by the thickest blanket of smog yet this summer, an acrid, choking haze from wildfires that have wiped out Russian forests, villages and a military base.

Passengers on Moscow's subway said the eye-stinging haze hovered above the platforms, and City Hall warned of health risks from the smoke, which is carrying harmful gases, including carbon monoxide.

"I woke up before dawn and thought I was going to die of suffocation," said Yadviga Pashkova, a frail, 62-year-old former schoolteacher who lives in central Moscow. "It felt awful because there was no way out."

To the east, firefighters focused on beating flames back from a top-secret nuclear research facility. In the capital, President Dmitry Medvedev fired several high-ranking military officials over what he called criminal negligence in fires that ravaged a military base.

Russia is suffering through its worst heat wave on record, a condition that has sparked forest and peat fires across its central and western regions that have killed at least 48 people in the past week. Temperatures for weeks have soared as high as 38 Celsius (100 Fahrenheit) in Moscow, where the average summer temperature usually is around 23 Celsius (75 Fahrenheit).

Over the last 24 hours, firefighters have extinguished 293 fires, but 403 others have been spotted and more than 500 others have continued to rage over large swathes of countryside, some of them out of control, the Emergencies Ministry said.

Dry winds have sent clouds of smog over Moscow before, but Wednesday's was the worst yet, with the haze obscuring the capital's landmarks and penetrating the subway system.

Moscow's 10 million residents were cautioned to protect themselves against the polluting smog, which came from wildfires in forests and peat bogs to the south and east. The bogs were drained in Soviet times to harvest peat, leaving them prone to wildfires.

Pollution indicators in the capital reached a "critical barrier" overnight and "even healthy people must take preventative measures," Moscow weather officials said. Residents were urged to face masks outdoors.

Humans were not the only ones suffering. The smoke and smog in Moscow also have sickened and killed wild and pet birds who are especially sensitive to air pollution, said Vladimir Romanov, director of The Green Parrot Hospital. He did not have specific figures.

Some 250 miles (400 kilometers) to the east, about 2,000 army troops and emergency personnel were fighting back flames that surrounded Russia's top nuclear research facility in Sarov.

The situation there was "tense but not critical," Deputy Defense Minister Dmitry Bulgakov said after new robotic firefighting equipment was sent to the scene overnight.

"There is no threat to the Federal Nuclear Center, and there is no reason for worry," Bulgakov was quoted by the ITAR-Tass news agency as saying. The country's nuclear chief, Sergei Kiriyenko, was quoted as saying that all explosive and radioactive material had been moved off site as a precaution.

The top-secret facility is Russia's main nuclear research center and the birthplace of Soviet nuclear weapons. Lawyers for the late Russian security agent Alexander Litvinenko, who died in London in 2006 after drinking tea laced with polonium, claimed the radioactive isotope that killed him was produced at Sarov.

Another risk of radioactive contamination stems from the forest fires sweeping through areas polluted by the 1986 explosion at the Chernobyl nuclear plant, Russian environmentalists said. The fires have the potential to send radioactive dust into the air, Nikolai Shmatkov of the World Wildlife Fund's Russia office and Vladimir Chuprov of Russian Greenpeace told The Associated Press.

But nuclear energy scientists said the danger came not from radioactivity but from fine particles in the smoke.

"The concentration of radioactive elements will be so negligible that the smoke itself will be many more times more dangerous than the radioactivity in it," Ravil Bakin of the Institute for Safe Development of Nuclear Energy told the AP. "Fine dust that contains chemical pollutants is the real danger and is much more poisonous than radioactivity."

In the tiny village of Peredeltsy about 125 miles (200 kilometers) southeast of Moscow, locals worried about their future after wildfires left their homes in smoldering ruins.

"I pray we won't be left in the street," said Yelena Savina, 27, who lost the home she shared with seven other family members. She said the fire approached the village so quickly on Sunday the family barely had time to escape.

"Everything burned in 15 minutes," she said of the village of about 20 houses, now surrounded by charred woodland. She said she was counting on Prime Minister Vladimir Putin to follow through on promises of 200,000 rubles ($6,600) compensation plus new homes.

Medvedev fired the chief of Russia's naval aviation and at least seven high-ranking military officials after fires burned at least half of the buildings at a military base near Moscow. Russian media said up to 200 naval aircraft may have been destroyed.

"If something similar happens in other places, in other agencies, I'll do exactly the same thing, with no sympathy," Medvedev said at a security council meeting Wednesday.

The weather this week will not likely help the firefighting efforts, as temperatures in Moscow and to the south and east were forecast to reach 38 degrees Celsius (100 Fahrenheit).
