Moscow smoke pollution worst in eight years
A heatwave has engulfed central parts of European Russia since mid June, pushing temperatures to the highest levels since records began and sparking forest fires that have killed at least 48 people.
"Air pollution surged four to ten times (above the maximum safe levels) in the early morning hours, which is an new high," Elena Lezina, an expert at the Moscow state agency that monitors air pollution, told Reuters.
The concentration of carbon monoxide in Moscow soared to about 5.7 times safe levels at night and the concentration of suspended particles tripled, she said.
Moscow has been shrouded in the worst smoke since 2002 when peat fires around the capital sent pollution levels soaring.
